MERCEDES-BENZ REVEALS FIRST PHOTOS OF ALL-NEW C-CLASS
Sleek New 2001 C-Class Sedan To Arrive On U.S. Shores Later This Year
MONTVALE, NJ – Mercedes-Benz has revealed the first photos and basic information about the long-awaited 2001 C-Class, an all-new sport sedan that promises to continue the impressive success of its predecessor. The current C-Class line has enjoyed a seven-year production run of over 1.6 million cars globally and is a market leader among comparable premium sedans. Available through U.S. retailers beginning this September, the all-new C-Class represents an investment of over $1 billion for the German automaker over the past four years of development.
A Fresh New Look, and Industry-Leading Safety Equipment, Too
The sleek new C-Class features a unique interpretation of the
familiar elliptical headlight design, resembling overlapping ovals with
a figure-eight outline. The sleek, eye-catching body shape is jam-packed
with useful, innovative technology, raising the bar yet again in its market
segment. The 2001 C-Class will come with such industry-leading standard
safety features as dual-force front airbags, head protection curtain airbags
and door-mounted side airbags, ESP stability control, Brake Assist, the
BabySmart child seat recognition system and the Tele Aid emergency call
system.
A V6-Powered Lineup for the U.S.
The C-Class lineup for the U.S. will be comprised of two V6-powered
models – the C240 and the C320. Both Mercedes-Benz V6 engines provide
spirited performance, yet with super-low exhaust emissions that attain
the coveted LEV or Low-Emission-Vehicle status. While the C320 will
come with a five-speed driver-adaptive automatic transmission with Touch
Shift, the C240 will be available with a choice of an all-new six-speed
manual or the five-speed automatic.
Mercedes-Benz USA projects that primary competition for the new
C-Class will include the BMW 3 series, Audi A4, Lexus ES300 and the Volvo
S70. While pricing will be established shortly before the late-summer
retail launch, the 2001 C-Class is expected to establish a new benchmark
for value in its market segment. 160

The new Mercedes-Benz C-Class: Top-class engineering
for exceptional dynamism and driving pleasure
· 20 innovations from the Mercedes flagship model fitted as
standard
· Design combines dynamism and elegance
· Extensive additions to standard equipment worth an extra
3700 DM
· Three lines for individual customer requirements
· Windowbags and sidebags fitted as standard
· Seven engines with up to 43% increase in torque
· Exemplary aerodynamics, with a Cd value of 0.26
Sindelfingen, Germany – After about four years of development and a
total investment of more than 1.36 billion Euro, the new Mercedes-Benz
C-Class is celebrating its world debut. The sedan will be available at
European branches and dealers of the Stuttgart-based auto maker from May
and will continue the success of its predecessor, which has enjoyed a production
run of 1.6 million units and is the market leader among comparable premium
sedans in many countries.
With the new C-Class, an extensive package of technical innovations
is being phased in, on an unprecedented level for this market segment.
Never before has so much attention been paid in this vehicle class to the
aspects of safety and comfort as in the development of the new Mercedes-Benz
C-Class, which with this top-class technology guarantees a maximum of both
dynamism and driving pleasure.
Even at first glance the attractive design, with its modern interpretation
of the twin headlamp face, expresses two of the key features of the new
C-Class, namely dynamism and elegance. The sedan is a youthful, progressive
car that is characterized by newly developed chassis technology, powerful
engines, the latest technical innovations and, in particular, sporty agility.
These dynamic features are combined in the new C-Class with traditional
Mercedes qualities such as the maximum possible safety, top quality, exemplary
comfort and superb reliability.
The standard equipment of the new sedan includes pioneering technical
innovations that were previously only available in the flagship models
bearing the Mercedes 3-pointed star: windowbags, adaptive airbags for driver
and front passenger, Headlamp Assist, the multifunction steering wheel
and fiber optics are only a few examples of a whole host of new developments
that make the C-Class a technological trailblazer in its market segment.
Overall, more than 20 technical innovations from the Mercedes flagship
models are included as standard in the new C-Class.
In addition, maximum safety is ensured by standard-fitted systems such
as the Electronic Stability Program (ESP®), Brake Assist, automatic
child safety seat recognition, seat belt tensioners and belt force limiters
for the front seats and rear outer seats, head restraints for all seats
and side impact airbags in the front doors. The SPEEDTRONIC electronic
speed limiter and the 6-speed manual gearbox are also fitted as standard.
Compared to the outgoing model, Mercedes-Benz has upgraded the value
of the standard equipment of the new C-Class by about 3700 DM.
Classic, Elegance and Avantgarde for individuality on the road
Three distinctive design and equipment lines provide an answer to the
modern demand for individuality. Whilst the basic Classic model has a classical
and reserved air, the Elegance line lives up to its name with an even higher
level of standard equipment and with chrome trim strips, alloy wheels and
a leather-covered steering wheel. In the Avantgarde version, the new C-Class
displays its most dynamic side, with blue tinted glass, textured aluminum
interior trim and 16-inch alloy wheels. The bumpers and side sills have
a unique design that also emphasizes the avant-garde character of this
model variant.
Voice control also available for the car radio for the first time
In the optional equipment range, Mercedes customers again benefit from
the technological advance of their brand. For the first time, some of the
groundbreaking systems of the S-Class are also available for the C-Class,
including the THERMOTRONIC sensor-controlled luxury automatic climate control,
the innovative COMAND display system, the DynAPS dynamic routing system
and the Bose sound system with automatic driving noise compensation. The
innovative LINGUATRONIC voice-operated control system that was previously
only available for the car phone can now for the first time optionally
also control the car radio and CD player.
New telematics services for C-Class drivers
The TeleDiagnosis and MB Info telematics services are also new. In
the event of a breakdown, at the touch of a button on the car phone, TeleDiagnosis
transmits all relevant vehicle data and the precise location of the vehicle
to the Mercedes-Benz Customer Assistance Center, so that the assistance
personnel can organize the necessary recovery or repair service as appropriate.
TeleDiagnosis operates in combination with the TELE-AID automatic emergency
call system.
All engines with substantial gains in power and torque
Dynamism and driving pleasure – these two outstanding characteristics
of the new C-Class are already guaranteed by the seven new or enhanced
engines. They deliver up to 20% more power and up to 43% more torque than
their counterparts in the outgoing series. All engines therefore provide
the optimal conditions for a dynamic driving experience. The power spectrum
of the four gasoline and three diesel engines ranges from 85 kW/115 hp
to 160 kW/218 hp.
Especially with the newly developed 2.0-liter supercharged engine,
the new C-Class is one of the most dynamic vehicles of its displacement
class. Thanks to the belt-driven supercharger, this 120 kW/163 hp 4-cylinder
engine achieves the performance characteristics of a larger 6-cylinder
engine. With a full 230 Newton meters, the new C 200 KOMPRESSOR accelerates
from standstill to 100 km/h in only 9.3 seconds. Its top speed is 230 km/h.
At the same time, the fuel consumption remains exemplary: compared to the
outgoing C 200, which developed roughly 20% less power and torque, the
new C 200 KOMPRESSOR consumes only 0.1 liter more fuel per 100 km, with
an average of 9.5 liters (NEDC overall consumption). The V6 engine with
3.2 liters displacement is also a newcomer to the C-Class. With 160 kW/
218 hp, this unit provides superior performance which makes it one of the
leaders in this market segment.
Mercedes-Benz has made major advances in the field of exhaust emissions:
the gasoline engines of the new C-Class already meet the strict EU-4 limits
which will only enter into force in 2005.
The performance of the diesel engines is also impressive. The new 5-cylinder
C 270 CDI reaches a top speed of 230 km/h and is therefore 27 km/h faster
than the outgoing C 250 TURBODIESEL. A variable turbocharger and the modern
common rail injection system have made these results possible and also
ensure that the new C-Class consumes 14% less fuel than its less powerful
predecessor. The C 200 CDI and C 220 CDI 4-cylinder engines are also equipped
with this technology, so that they too, with 6.1 and 6.2 liters per 100
kilometers respectively (NEDC overall), combine higher power with lower
fuel consumption than their outgoing counterparts.
Modern operating and display concept to ease the load on the driver
An advanced operating and display concept increases the comfort and
driving pleasure on board the new C-Class. More than ever before, modern
technology is relieving the driver of various burdens by performing many
functions automatically. With the aid of the new multifunction steering
wheel and the central display in the speedometers, the driver can program
more than 50 individual settings and call up important information simply
by thumbing the appropriate button.
High-grade interior materials testify to the premium character of the
sedan and ensure pleasant haptic qualities and spatial comfort. The cockpit
is crafted to measure: the armrests, the new multifunction steering wheel
and the gear lever form a near-perfect ergonomic unit. The driver has everything
to hand immediately on taking up position in the driver's seat. The standard
rake and reach adjustment of the steering wheel and the many possible variations
in seating position ensure outstanding interior comfort.
Drag and lift considerably reduced
The new Mercedes-Benz C-Class also sets trends in body design. For
example in aerodynamics: with a Cd value of 0.26, the new C 180 is the
most aerodynamic notchback in its market segment. At the same time, Mercedes
engineers have reduced lift on the front and rear axles by up to 57%, thereby
establishing optimal conditions for superb driving stability.
Easy-to-repair crash boxes in the front end structure
The front end structure of the new sedan comprises a front module with
crash boxes made of high-strength steel. These modules are bolted to the
body and can therefore be rapidly and inexpensively replaced after a crash.
In minor bumps at up to 15 km/h, the front module absorbs the entire impact
energy, so that the structure of members behind remains undamaged. Mercedes
engineers have also developed a similar easy-to-repair construction at
the rear.
Newly developed 3-link front axle for perfect driving dynamics
In the key disciplines of chassis development, the new C-Class achieves
top-rate results. Mercedes engineers have spared no effort in redesigning
or improving the suspension, steering and brakes in order to surpass the
already high standards of the outgoing model. The progress achieved is
evidenced in exemplary agility, precise directional stability, high steering
precision, excellent ride comfort, good braking efficiency and supremely
assured handling all the way to the limit.
The suspension innovations include a newly developed 3-link front axle
with McPherson struts, a modern rack-and-pinion steering system and generously
dimensioned disk brakes with improved cooling air flow for maximum braking
comfort. The multi-link rear axle has been entirely redesigned and retuned.
The new C-Class measures 4526 millimeters in length and is therefore
10 millimeters longer than the outgoing model. The wheelbase has been increased
by 25 millimeters to 2715 millimeters.

process naturally remains our demanding Mercedes Quality Standards.
Helmut Petri, member of the management board of the Mercedes-Benz
passenger car and smart division, head of Production
Model concept and equipment:
Dynamism and driving pleasure as goals of development
· Three lines for individual customer requirements
· Substantial upgrading of standard equipment
· High tech à la S-Class as standard and as optional
extras
· Number one among premium cars in this class
Success is based on ability, and leadership on know-how. The ability and know-how of its engineers have made Mercedes-Benz the technological leader among automobile manufacturers. That was always the case, but never before has the company produced such a firework display of major technical innovations in such a short time as in recent years. ESP®, windowbags, 3 valves per cylinder with dual ignition, Brake Assist, seat belt force limiters, COMAND, LINGUATRONIC, TELE-AID, adaptive airbags and dynamic routing – these are just some of the many milestones in ground-breaking automotive technology that first entered full-scale production at Mercedes-Benz. Each of these innovations provides greater safety, increased comfort and lower fuel consumption, all combined with greater driving pleasure.
New developments of this nature require high investment. DaimlerChrysler invests about 35 million DM per day to convert research and development projects into production-ready systems for new cars. This high cost also dictates the prices of innovations. Consequently, top-level technology is often reserved purely for the flagship models at first and only finds its way into large-scale production after quite some time. At Mercedes-Benz, buyers of the C-Class now also benefit from the technical advances featured in exclusive flagship models of the brand. Innovations from the S-Class are being included in the C-Class, making the new sedan the technological leader of its market segment. The list of innovations that bring S-Class safety and comfort to the C-Class is long: windowbags, adaptive front airbags, Headlamp Assist, central display, multifunction steering wheel and fiber optics are examples of the features that are part of standard equipment of the C-Class. These are combined with major new developments that make their debut in the new sedan, confirming its role as a trendsetter.
Standard equipment upgraded by up to 3700 DM
Mercedes engineers have combined these innovations into an overall
concept that gives new meaning to the concepts of driving pleasure and
dynamism in this vehicle class: the C-Class is a youthful, progressive
car that drives the way it looks – dynamically and with agility, without
forsaking the traditional Mercedes virtues of quality, comfort or safety.
Nor is individuality forgotten, since Mercedes customers have many ways
of giving "their" C-Class a highly personal character. Three distinctive
design and equipment lines provide the basis for this variety, and a full
range of useful and innovative options round off the individualization,
making each sedan an unmistakable unique edition. The line names are Classic,
Elegance and Avantgarde, aptly describing the different characters of the
model versions:
In the Classic line, the new C-Class comes across as a classic and
reserved type that does not reveal at first glance what is hiding under
the surface. The body design renounces the use of chrome trim strips, shiny
trim panels or other ornamental components but concentrates on emphasizing
the original qualities of the sedan. This restraint is the principal attraction
of the line, which despite its understated character gives a highly up-to-date,
contemporary and also sporty impression that is especially strengthened
by the color-matched bumpers, side sills and rub strips. Four colors are
available for adapting the interior to individual taste – anthracite, orion
gray, pacific blue and quartz. These colors harmonize with the standard
high-grade "calyptus linea" wood trim in the center console. The Classic
model also contains all the technical and comfort features that make it
a genuine Mercedes-Benz:

A touch of the S-Class upgrades the interior, with the tone being set by high-grade wood on the center console and doors, fine leather on the steering wheel and gear lever and a tasteful fabric design. Chrome trim strips on the bumpers, side rub strips, door handles and radiator grille lend the sedan a more imposing outward appearance. The aluminum trim strips on the waistline and roof are anodized in hematite color, and the elegant appearance is further enhanced by the high-gloss fins in the radiator grille and the standard-fitted 7-hole alloy wheels. Many additional detail features of the standard equipment (compared to the Classic) accentuate the outward appearance and provide the occupants with even greater comfort.

· "Cambridge" fabric design
· Bumpers with chrome strips
· Door handles in body color with chrome strips
In the Avantgarde line, the C-Class reveals its most dynamic and individualistic side. Blue tinted glass, interior trim elements made of textured aluminum and 16-inch alloy wheels are hallmarks of an exclusive character with a conscious air of impudence and originality. Even the bumpers and sill covers have been given a unique form by designers in order to emphasize the special appeal of this model version and to bring an even more sporty feel to the general appearance. For the interior, the choice of colors is between anthracite and Orion gray, whilst for the exterior Mercedes designers are offering the additional exclusive paint color of amethyst violet. The other items of standard equipment correspond to the desire of the young and young at heart for a car with exceptional flair:
Additional equipment of the Avantgarde line (compared to Classic):

The AMG styling package developed by Mercedes-AMG has a functional
and sporty design that emphasizes the dynamic character of the new C-Class.
The overall sporty impression is accentuated at the front by the air dam
with integral fog lamps and also by the special side sill skirts and rear
skirt.
Up to 40% conquest rate for the C-Class
Since 1993, the letter "C" for Mercedes-Benz has stood for a model
range that has justly earned its reputation as a winner. Overall, to this
day, about 1.85 million drivers have opted for a C-Class model, and between
1993 and 1999 about 1.6 million new registrations were recorded for this
sedan.
In many countries of the world, the C-Class was and still is the number
one car among comparable rivals – especially in the USA, Japan and its
home country of Germany, where the Mercedes model has obtained an average
share of just under 20% in its comparable segment over the last few years.
In western Europe as a whole, the market share stood at an average of 14.7%
between 1994 and 1999.
With a conquest rate that attained about 40% in many countries, the
outgoing C-Class already won over new customers daily to the Stuttgart
auto manufacturer. There is no doubt that the new sedan combines all the
criteria to take this triumphant run to new heights and sell even more
units. According to market researchers, over the next few years, not only
will general customer interest in cars of this class be increasing, but
also the demand for models with premium character will rise. The growth
regions will particularly be the USA (+27%), Japan (+22%) and the countries
outside the Triad (+59%).
So all the signs augur well for the new car with the "C" in its nameplate
to be a winner, too.
Design: Affection at first glance
· A successful balance of dynamism and elegance
· Updated interpretation of twin-headlamp face
· Distinctive waistline as a symbol of power
· High qualitative appeal in the interior and excellent tactile
properties
Character formation - this was the designers’ brief. They were tasked
with giving the new Mercedes-Benz C-Class a dynamic character which both
instills affection and from the very first glance leaves no doubt about
its pedigree. In short, the resulting sedan had to visually reflect Mercedes-Benz’s
new, progressive brand image. But, in addition to sporty dynamics and youthful
attractiveness, the remit also specified embodying the typical elegance
of a Mercedes sedan. The design of the new C-Class is a study in integration.
It unites different worlds and spontaneously grabs the attention of people
with completely different aspirations and interests. Three design and equipment
lines simplify the realization of individual wishes in terms of form, colors
and materials.
Dynamism and elegance, that was the aim. Some two dozen designers set
to work, committed their visions and ideas to paper, discussed many hundreds
of sketches and transferred the best of them to the virtual world of the
computer so that they could experience them in three dimensions on special-surfaced
screens. The choice finally fell on a draft design which unites all the
objectives in optimum fashion: dynamism, emotional appeal, elegance, solidity
and continuity - in other words, the typical Mercedes language of form.
Twin headlamps merge into harmonious units
The headlamps are again character-shaping features. While the famous
twin-headlamp face of the E-Class in 1995 was the visible signal of a new
departure for the Mercedes-Benz brand, the C-Class re-interprets this symbolism,
thereby marking the launch of the next stage in Mercedes-Benz’s product
offensive. Although the sedan’s four ”eyes” are still identifiable , the
design of the new C-Class has seen the oval headlamps merge into harmonious
units in line with the basic brief of integration. The hood and fenders
pick up this rounded finish and continue it backwards in sweeping curves,
forming elegant sheet-steel sculptures. Associations with the human anatomy
are inescapable, as the shape of the fenders is reminiscent of the muscles
of trained athletes.
Seen through the eyes of the designers, these athletic forms enhance
the width of the car’s body, giving a powerful appearance particularly
when viewed from the front. This effect is reinforced by the bumper which
is perfectly integrated in the bodywork with the discreetly molded spoiler
edges in the lower section and the front fog lamps, especially as all the
components use the same paintwork - in body color - and therefore present
a unified whole in color terms too.
The interplay of dynamism and elegance is also seen in the radiator
grille and headlamps. The designers have skillfully worked with different
rake angles here to draw attention to the new C-Class’s two features: while
the slightly raked headlamps are reminiscent of a sports car, the fins
and webs of the radiator grille are decidedly more upright. The effect
of optically stretching the hood in this way is to give the car power and
elegance.
Seen from the side: pronounced wedge-shaped body and powerful shoulders
Seen from the side too, the dynamic character of the new C-Class is
the dominant first impression. This is ensured primarily by the pronounced
wedge-shaped body which is particularly defined by the curve along the
waistline. The conscious emphasis on what is generally known as the waistline
actually calls to mind the broad shoulders of a well-built athlete, topped
by the side windows, roof pillars and roof. This line runs continuously
from the front to the rear end, giving form to the power of the body -
particularly at the rear where the striking C-pillars meet it and jointly
define the form of the rear end.
But the powerfully raked windshield, the coupé-like roof, and
the flat backlight are unmistakable signals of a spirited use of forms
with stylish emphases from the world of luxury sedans.
Like the headlamps, the rear lamps are now also regarded as typical
stylistic elements of new Mercedes models with a sporty yet elegant character.
The tail lamp covers extend in a wedge shape into the flanks of the body,
underlining the car’s sporty lines. This overlapping lamp design was first
used on a standard-production car in the SLK roadster and then also caught
the eye in the S-Class and the top-of-the-range CL coupé - not just
because of its striking shape but also as an integrating style element
for formally linking the side and tail sections.
Further similarities with other Mercedes models are seen in the V-shaped
cut-out in the tail of the new C-Class, which is also formed by the tail
lamps. They ensure the formal integration of the entire rear end – creating
the visual links between the fenders, trunk lid and bumper. At the same
time, the trapezoidal tail lamp design and the large-format bumper emphasize
the width of the sedan, which therefore also makes a particularly powerful
impression from the rear. The bumper merges almost seamlessly into the
body and also forms a unified entity in color terms with the elegant metal
skirt.
The interior is dominated by the harmony of form and color
Sporty elegance - this essential feature of the new C-Class is immediately
apparent on getting into the car. The cockpit seems made-to-measure. The
armrests, the new multifunction steering wheel and the gearshift lever
form a perfect ergonomic whole - the driver takes his seat and has everything
immediately within reach.
Beautiful forms, high-quality materials and modern color combinations
define the visual framework of this ergonomically consummate cockpit. The
outer air vents almost seem to be hovering, while the lower section of
the dashboard flows almost seamlessly into the door linings. The dashboard
is split into two, with the upper half consciously made dominant. The controls
are not designed as individual switches, but instead are grouped together
in special integrated panels.
Fine materials to ensure a special ambience and excellent tactile
qualities
The selection of materials is just as important. Wood, aluminum and
leather are important elements of style which define the individual and
high-quality character of the interior of all the versions of the various
lines:
· Wood: This is used to trim the center console and door linings
of the Elegance line. Even the entry-level Classic version leaves the production
line with trim sections made of dark brown ”calyptus linea” wood, while
for the Elegance the designers have chosen ”laurel” wood.
· Aluminum: This high-quality material is reserved for the Avantgarde
line. It has a discreetly textured surface which gives the material its
name: alu-quadra. Mercedes-Benz use this printed aluminum for the center
console and door trim strips of the Avantgarde line.
· Leather: This soft natural material is used as standard in
the Elegance and Avantgarde models to cover the steering wheel, gearshift
knob and gearshift boot. The color is matched to the particular upholstery
color. An optional extra which also includes leather for the seat covers
and door linings is available for the Elegance and Avantgarde lines.
All materials used are of high quality and pleasant to touch – it quite
literally is a case of take your seat and enjoy.
Body: Tailor-made down to the smallest detail
· Body stiffness improved by 26%
· New ellipsoid firewall for optimal occupant protection
· Easy-to-repair front module with integral crash boxes
· Anti-corrosion treatment geared to practical conditions
with double-protected panels
· Exemplary Cd value of 0.26
· Lighting system with new convenience features
The term C-Class has long meant more to Mercedes-Benz than just a successful
sedan. The C-Class has developed into a complete model family and also
provides other Mercedes cars with a solid technical foundation. The same
will hold true for the new model range.
In the core disciplines of body technology, the new C-Class sets trailblazing
trends, as the results of various tests on the test stand confirm:
· The static torsional resistance of the body structure (without
windows) attains a new top result for this vehicle class, with 3.57 millimeters
per meter. This value surpasses the good result of the outgoing C-Class
model by more than 26%.
· The solidity of different body parts such as the center tunnel
and side members – measured in terms of static flexing – is up to 50% higher
than for the outgoing C-Class.
· The dynamic resonant frequencies for torsion and bending of
the new sedan are up to 12% better than for the outgoing model.
The occupants of the new C-Class will feel the benefits of these advances
especially in the improved acoustic and vibration comfort and in enhanced
crash protection.
Recycled materials and natural materials are part of the materials
concept
In addition to aluminum and plastic, the material composition of the
new C-Class is still dominated by steel, as the proven material, but the
proportion of high-strength panels, which combine minimal panel thickness
and weight with a maximum of strength, has been more than doubled compared
to the outgoing model. One new feature in this field of material technology
is the ”dual phase” steel. Its high strength conferred by its two-phase
microstructure withstands high crash stresses and therefore plays an essential
part in the high solidity of the front end and occupant cell.
Recycled materials and natural materials are all part of the materials
concept for the new C-Class. Mercedes-Benz have approved a total of 38
plastic components with an overall weight of some 30 kilograms for the
use of recycled materials; this represents about 13 percent of all plastics
used. A further 33 components in the sedan are made of natural materials
such as wool, cotton, coconut, wood and other cellulose fibers. They weigh
just under 23 kilograms in total – some 27 percent more than in the outgoing
model. Thanks to its environmentally acceptable materials mix, the new
Mercedes-Benz C-Class achieves a recycling potential of over 85 percent
by weight and therefore already meets the provisions of Germany’s Scrap
Car Decree which will not come into force until 2002.
New firewall concept for even better occupant safety
The new firewall is assembled out of six different individual components
of differing panel thickness. In this way, Mercedes engineers adapt the
material to the relevant load and obtain an ideal compromise between lightweight
construction and crash safety. The special forward-arcing curve of this
innovative part also gives it its name: the ”ellipsoid firewall”. As in
the Mercedes-Benz S-Class, this large part plays an important role in the
safety concept of the new C-Class, since it is not only able to withstand
extreme loads but can also distribute crash impact forces evenly over a
wide area, thereby preventing dangerous intrusions into the occupant cell.
In the outgoing C-Class, this function was performed by the forked side
members, which are now no longer required.
Front module and crash boxes reduce repair costs
The Mercedes-Benz S-Class and flagship CL Coupe also provided the inspiration
for the development of other front end components. For example, the front
module consists of an independent unit that provides the same advantages
in each body version. Bolts reliably connect the module to the remainder
of the body. Even the individual sheet metal parts inside the module are
bolted together, so that accident damage can be remedied faster and at
lower cost. Welding is no longer required when replacing individual components
or the entire front module. The key components of the front module are
two steel crash boxes that absorb the impact energy of minor frontal collisions,
thereby preventing damage to the load-bearing structure behind. The advantage
of this system is that the crash boxes and load-bearing members are fastened
together by bolts and can be replaced without problem after an accident.
This cost-cutting crash concept is operative for crash speeds of up to
15 km/h against a rigid obstacle.
High-strength crossmembers and robust doors for side impact protection
In a side impact crash, three crossmembers in the floor area and a
solid square profiled section under the instrument panel enter into action
to strengthen the passenger compartment. The single-piece outer panel of
the side wall conceals individually welded inner shells that confer even
greater strength to the roof pillars, roof frame and outer side members.
The doors too consist of an outer and an inner shell and of several inner
sectional reinforcements. In addition, a flexible tubular member is fitted
in the lower part of each door to reduce the deformations in a side impact
crash.
Soundproofing foam elements in cavities
Strength and safety were not the only goals in the design of the occupant
cell: the question of noise comfort was also on the agenda from the start.
In this field, body engineers have made a major contribution by filling
certain cavities of the bodyshell with foam or fiber materials. These elements
are first mounted on special support plates and firmly fastened to the
body – then, in the drying zones of the paint shop, these soundproofing
materials expand automatically and completely fill the cavities. Overall,
42 of these foam or fiber elements are concealed beneath the metal skin
of the new C-Class. Each of the two side walls alone contains 11 foam absorbers.
Steel panels with double corrosion protection ensure longevity
In many European countries, Mercedes-Benz gives its new car buyers
a cost-free long-term warranty for mobility and sustained value. ”mobilo-life”
is valid for 30 years and also includes comprehensive warranty services
in the event of rust perforation of the body and underbody, provided that
the car has been regularly serviced and maintained by an authorized Mercedes
workshop.
This warranty promise is based on comprehensive corrosion protection.
For the new C-Class, the engineers in Sindelfingen have again enhanced
the rust protection measures. Three main aims were pursued: economical
use of materials, avoidance of waste and the rejection of environmentally
critical materials. The result is a bodyshell that has 85% of its total
surface protected against corrosion by zinc coating. By comparison, in
the outgoing model, the share of zinc-coated panels was ”only” 65%.
Instead of an all-round fully galvanized body, Mercedes-Benz relies
on steel with dual corrosion protection: electrolytically zinc-plated panels
are additionally coated with an organic paint that also contains rust-inhibiting
zinc pigments. Although this paint is only two to four micrometers thin,
it withstands the stresses generated by pressing and spot-welding the panels,
thereby ensuring lasting protection. Almost half of the galvanized body
parts of the new C-Class are made of this innovative steel sheeting. For
the front end, side members, A-pillars and the inner shells of the doors,
hood and trunk lid, Mercedes-Benz uses sheeting with organic coating on
both sides. This coating therefore also replaces conventional cavity sealing
in many areas.
Mercedes engineers have also been able to dispense with the conventional
PVC underseal in the new C-Class, whilst nevertheless still guaranteeing
long-term corrosion protection in this area. The solution to the problem
is an underbody encapsulation made of glass-fiber reinforced plastic, which
also offers aerodynamic advantages.
Exemplary Cd value of 0.26 means best-in-class aerodynamics
When driving on the motorway, more than half the fuel consumption of
a passenger car can be attributed to wind drag. That fact alone explains
one of the reasons why Mercedes engineers have committed themselves so
intensively to the subject of aerodynamics for many years. In the new C-Class,
this commitment is crowned with particular success: with a Cd value of
only 0.26, the new C 180 is the most aerodynamic notchback sedan of its
market segment in the world.
Compared to the outgoing model, the aerodynamics engineers at Mercedes
have been able to reduce drag by a full 13%, thereby bettering even the
exemplary Cd value of the E-Class and S-Class (0.27), previously the best
attained in this aspect of body development. The product of frontal area
(A) and drag which crucially affects fuel consumption is about 13 per cent
lower than the comparable figure for the outgoing C-Class, as the following
table shows:
New C-Class Outgoing model
Frontal area m² 2.08–2.09 2.07
Drag Cd x A m² 0.54–0.57* 0.62–0.64*
Cd value 0.26–0.27* 0.30–0.31*
*Depending on engine version and tire size.
The exemplary Cd value of 0.26 is essentially due to the following
body details:
· Front air dam and rear skirt: Their function is to control
the slipstream, diverting it to the sides at the front, so that it flows
back smoothly and finally parts from the body at the rear with little turbulence.
· Spoiler lip on the trunk lid: this elegant detail improves
the escape of the slipstream, reducing lift and preventing the formation
of turbulence behind the body.
· Wheel spoilers at the front and rear wheels: these small plastic
elements reduce the back pressure of the air in front of the tires, thereby
reducing the Cd value. At the same time they reduce lift.
· Underbody encapsulation: The large, smooth plastic panels
that reach back to just in front of the rear axle allow the slipstream
to flow back underneath the body without turbulence.
· Engine compartment encapsulation: Complete encapsulation of
the engine compartment not only improves acoustic comfort but also guides
the slipstream accurately downwards and prevents the air swirling in the
engine area.
Superlative aerodynamics provide excellent directional stability
A minimal coefficient of drag is not the only thing that counts for
Mercedes-Benz aerodynamics engineers. They are only happy if their work
also serves the interests of road safety. The keyword here is lift: the
sedan is characterized by exemplary stability, as is proved by the measurements
for front and rear body lift, which are up to 57% lower than the equivalent
values for the predecessor model. This is due to the new encapsulation
concept for the underbody, the wheel spoilers for the front and rear wheels,
the elegant spoiler lip on the trunk lid and the newly developed flare
elements in front of the front wheel arches.
New lighting functions for greater safety and comfort
In the C-Class, the driver no longer has to worry about switching the
headlights on and off, because this task has been taken over by electronics
with the aid of a light sensor mounted on the windshield. This ”Headlamp
Assist” system, as it is called, which until recently was only available
for luxury sedans and top sports cars, is now included as standard in the
new Mercedes-Benz C-Class. This comfort function is programmed by the multifunction
steering wheel on the central display in the instrument cluster and is
activated by the light switch on the instrument panel (”Auto” position).
In addition, electronic data bus networking on board the new sedan permits
a wide range of additional lighting functions and switching facilities
that enhance both safety and comfort:
· Emergency light: If a data line or electronic control unit
is defective, a preprogrammed circuit prevents failure of the entire vehicle
lighting system.
· Failsafe lighting: If bulbs important to vehicle safety go
out, the electronic system automatically switches on other lights that
can provisionally replace the defective light.
· Daytime driving lights: The driver can program the light system
of the
C-Class to switch on the low beam headlights, parking lights, rear
lights and license plate light automatically after switching on the engine.
· Headlight switch-off delay: Optionally, the headlights remain
switched on even after the occupants have left the car in order to help
them find their way around in the dark.
Four lighting functions in a single headlight housing
The headlights are not only important design features of the new C-Class
but also set an example by their modern technology. The large rounded plastic
lenses cover a two-chamber reflector that combines four lighting functions:
the outer zone is used for low beam and, above it, the turn signal light,
whilst the inner reflector surface is reserved for the high beam headlight
and sidelight. In other words, in the interests of increased light output,
the low beam and high beam are housed separately. The fog lamps are housed
in the front bumper trim.
Also new are the exterior mirror housings with integral turn signal
repeater lights. In this high position they attract particular attention
and therefore offer clear safety benefits.
Xenon light and high-pressure headlight cleaning available as an
option
Instead of the standard H7 bulbs for the low beam headlights, Xenon
headlights with gas discharge lamps are optionally available to provide
an illumination similar to daylight. These headlights are characterized
by twice the light intensity, longer service life and a lower power consumption
of only 35 Watts. Dazzling of oncoming traffic is prevented by a dynamic
headlight range adjustment system. With the aid of inclination sensors
on the front and rear axles, this system detects brief movements of the
car body when starting from rest, braking or accelerating. Consequently,
the reflectors always follow the current body position and adapt the angle
of the beam accordingly. The newly developed headlight cleaning system
uses water-jet technology. A telescopic nozzle unit is mounted under each
headlight, behind the bumper trim. This telescopic unit is extended at
the touch of a button and in response to the water pressure to reveal two
cleaning nozzles that spray a precisely metered quantity of water against
the lens.
The rear lamp units of the new C-Class are recessed deep into the vehicle
sides and contain the brake light, turn signal light, rear light and reversing
light, together with the rear fog lamp on the left-hand side. The brake
lights in the rear lamp units are coupled to the third raised brake light
in the trunk lid. This third brake light consists of 20 LEDs that light
up about 50 milliseconds faster than conventional bulbs in response to
the brake pedal. The LEDs therefore make a major contribution to the prevention
of rear end accidents.

Safety: Real-life safety in six stages
· Sophisticated front-end structure with crash boxes and
new firewall
· Airbags with two-stage gas generators for driver and front
passenger
· Windowbags as standard for excellent side impact protection
· Belt tensioners and belt-force limiters even at rear
When Mercedes engineers consider concepts for the further improvement
of vehicle safety, only one standard counts: real life. All new developments
or enhancements that provide car occupants with greater safety are invariably
based on careful analysis of actual traffic conditions and accident processes.
The upshot is that today's new C-Class benefits from more than six decades
of experience of Mercedes safety development rooted in practical observation.
The technical safety concept of new Mercedes passenger cars is largely
defined not only by the various test specifications laid down by different
international bodies but also by the findings of in-house accident research.
Consequently, the term safety will in future mean more than just crash
safety: more than ever before, the theme of safety is governed by an integrated
approach that covers the whole ground, starting with questions of accident
prevention by means of electronic assistance systems and ending with the
fastest possible rescue of the vehicle occupants after a crash. The new
C-Class is an outcome of this pioneering ”Real-Life Safety Concept”, which
essentially consists of six stages:
1 Danger warning Sensors on the axles and bodywork monitor the car’s
handling characteristics. On reaching the limits of driving dynamics, a
yellow warning symbol lights up in the cockpit.
2 Accident prevention Standard-fitted assistance systems such as ABS,
Brake Assist and ESP® automatically enter into action in critical situations,
thereby helping the driver to keep everything under control.
3 Minor knocks The impact energy of minor bumps at speeds of up to
15 km/h is absorbed by the bumpers and crash boxes in the front-end module.
The inertia reels on the seat belts are locked. Sensors monitor the severity
of the accident and prevent the airbags being inflated until their supplementary
protective effect is actually needed.
4 Impact In a severe collision, robust members in the front, side and
rear structures absorb energy and distribute the impact forces over a wide
area. The belt tensioners are activated. Depending on the severity of impact,
the front airbags initially inflate less than fully, in line with actual
need, so that the optimal protective effect is assured. In a side-on crash,
the occupants are protected by sidebags in the front doors, combined with
windowbags. For the front passenger seat, the automatic seat occupancy
and child seat recognition system prevents the passenger-side front airbag,
belt tensioner and sidebag being activated if not actually needed. The
fuel supply to the engine is cut off.
5 Occupant protection In the event of even greater danger to the vehicle
occupants, a second inflation stage for the front airbags is triggered.
At the same time, the belt force limiters are also activated.
6 Emergency rescue After an accident, the doors are automatically unlocked.
The TELEAID emergency call system (optional) alerts the rescue service
and guides it to the accident site. The hazard warning lights are switched
on.
Front-end impact: occupant protection in three stages
In order to take into account all possible accident conditions, an
integrated approach to body design is required. The new C-Class is proof
of this fact: in a front-end crash, depending on the severity of impact,
a three-stage protection system enters into action, with due attention
to both the aspect of cost-savings in accident repair and the typically
high Mercedes requirements for occupant protection:
1. Up to a collision speed of 4 km/h, the foam elements in the bumpers
absorb the impact energy, so that the metal panels behind remain undamaged.
2. Up to a collision speed of about 15 km/h, the impact energy is absorbed
by the newly developed front module and the two crash boxes made of an
innovative, high-strength dual-phase steel.
3. At a collision speed of more than 15 km/h the robust side members
in the front-end structure come into their own and absorb the impact energy.
The load is distributed to four mutually independent zones, as follows:
via the aluminum crossmember of the front module, which transfers the impact
forces of the offset crash to the side not directly involved; via the side
members, which extend far to the front (behind the crash boxes); via the
robust sectional panels above the wheel arches and via the front wheels,
which are supported on special impact-absorbing elements in front of the
side members (rocker panels), thereby transferring impact forces to the
body's side structure. Another important feature is the newly developed
ellipsoid firewall, which is joined to the front side members and spreads
the impact forces over a wide area.
Front airbags: two-stage inflation dependent on severity of impact
The front airbags of the new C-Class also adapt to the specific accident
situation and thereby provide even more effective occupant protection.
The era of these innovative adaptive restraint systems began in 1998 in
the Mercedes-Benz S-Class: the Stuttgart-based auto manufacturer has now
further developed this technology and for the first time is providing the
C-Class with two airbags that inflate in two stages as a function of the
severity of impact. In other words, like the body structure of the new
sedan, the restraint system is not solely designed to respond to high-speed
collisions but also for the first time takes into account the special protective
functions required for low to medium impact forces.
The technical explanation behind this system is that both the driver's
and front passenger's airbags are fitted with two-stage gas generators.
If the sensor system detects a minor front-end impact, it fires only one
chamber of these inflator units, so that the airbags are only partially
filled. Consequently, the airbags catch the occupants ”softly”. According
to accident research, this feature is especially advantageous in collisions
in the speed range between 20 and 35 km/h. If the airbag sensors register
a higher accident load, the electronic control unit also activates the
second chamber of the inflators, and the airbags are fully inflated. Depending
on the severity of impact, this second airbag stage is triggered within
only 5 to 15 milliseconds of the first.
The adaptive airbag system of the new Mercedes sedan includes a sensor
system that decides whether or not to activate the protection system. For
example, the airbag, belt tensioner and the sidebag on the front passenger's
side are deactivated if the front passenger seat is unoccupied. A sensor
mat in the seat cushion provides the necessary information to the electronic
control unit. If the car owner installs a ”reboard” child safety seat from
the Mercedes-Benz accessories range, special antennas in the front passenger
seat exchange data with a transponder in the base of the child seat. The
airbag electronic system therefore recognizes that a reboard child seat
has been fitted and immediately deactivates the airbag on the front passenger's
side, since it is not required in these cases. On the other hand, the belt
tensioner, sidebag and windowbag remain activated.
Highly robust protective zone for the occupants in a side-impact
crash
The importance of side impact protection for the safety concept of
modern passenger cars is continuing to increase. According to accident
research, the proportion of side impact collisions in traffic accidents
involving injuries to car occupants has more than doubled since 1985 –
just under 44% of all car accidents with fatal consequences are now in
the side impact category. Mercedes engineers have responded to these practical
findings with a comprehensive package of measures, which, like the front
occupant protection system, is primarily geared to actual accident situations.
It is effective at three levels:
1. In the floor area, reinforced side rocker panels transfer
the impact forces to two robust side members on each side under the front
seats and to a full-width crossmember underneath the rear seat. The center
tunnel reinforcements also improve the transfer of forces between the front
seats.
2. At medium height, the occupants are protected by laterally
stiffened doors integrated in the side panels and with several sectional
reinforce-ments, robust door hinges, and also by the extra-strong frames
of the seats and backrests. A square-section member under the dashboard
also improves lateral support.
3. In the roof area, intrusions are kept to a minimum by the
A, B and C-pillars with their full-height 3-shell construction and by a
reinforced roof frame, which is again of 3-shell construction.
The highly robust occupant cell, which provides optimal protection
in front-end and side impact collisions, is also highly effective even
in the event of an offset rear-end impact at high collision speeds. The
secondary load-bearing member structure and the newly developed rear end
module perform similar functions to the comparable components at the front
and are geared to actual accident processes.
Sidebags and windowbags as standard
Another important example of the Real-Life Safety Concept of the new
C-Class is provided by the standard-fitted windowbags that have already
proved their protective effect in the Mercedes S-Class, E-Class and flagship
CL Coupe models. The development of these special airbags is based on the
results of updated accident analyses on the risks of injury in side impact
collisions. Scientists found that these accidents involved a broad range
of angles of impact, so that the movements forced upon the car occupants
could differ vastly, thereby limiting the protective effect of more simple
solutions.
Consequently, in the opinion of experts, an airbag covering as wide
an area of the side of the car as possible is necessary in order to provide
optimal protection to the heads of the occupants in particular – both at
front and rear – in the many conceivable crash configurations. The result
is the windowbag. This special airbag meets the requirements of accident
researchers and provides excellent results even in the side impact crashes
that deviate from the standard right-angled configuration used in most
crash tests conducted by international test institutes. The airbag consists
of 9 chambers with a total volume of 12 liters. After a crash, it inflates
to span like a curtain from the front to the rear roof pillar of the interior.
Whereas the sidebags particularly protect the chest area, the windowbags
prevent the occupant's head striking the side window, roof pillars or roof
frame. In other words, sidebags and windowbags belong together. Consequently,
Mercedes-Benz fits sidebags as standard to the front doors of the C-Class
and offers them as options for the rear.
Front airbags for the driver and passenger, door-mounted sidebags and
standard-fitted windowbags are all part of the comprehensive restraint
system which ensures maximum occupant protection at all levels. The system

Interior: Premium-class comfort
· High-grade materials for a special experience
· Ultra-modern electronic systems to relieve the load on
the driver
· Cockpit with clearly arranged controls and multifunction
steering wheel
· More than 50 individual settings accessible via central
display
· Newly developed seats with power height and backrest adjustment
· Choice of two systems for perfect climate comfort
You feel it immediately on the first encounter: the Mercedes-Benz C-Class
has matured even further and is even more comfortable than before. The
design of the interior, its materials, equipment and classy appeal emphasize
the premium character of the sedan even more strongly than in the outgoing
model. Anyone who sits in one of the two newly developed front seats will
feel immediately at ease and will have no trouble finding exactly the desired
position. All the most important driving controls – the gear lever,
ventilation outlets, pushbuttons and adjusters – are arranged within easy
reach of the driver, and their functions are instantly recognizable. Everything
is literally to hand and in view.
One of the main aims has been ”rational automation”, so that the driver
can concentrate on the essentials, namely the traffic situation and the
driving experience. As a result, certain functions on board the C-Class
are automatically controlled and monitored. These functions focus on the
routine tasks of drivers, thereby relieving the pressure exactly where
most needed. Examples from a wide range of settings:
· Once programmed and set on the light switch, the exterior
lights are automatically switched on in dark conditions.
· All open windows and the sunroof can be closed with a single
touch of a button on entering a tunnel or underground parking garage.
· Once programmed, on inserting the ignition key, the seats,
steering wheel and rear view mirror move to the position desired by the
front occupants. The key also stores the settings of the automatic climate
control.
· Once programmed, on removing the ignition key, the driver's
seat is always moved back and the steering column automatically raised
for a more comfortable exit.
· Once activated, the optionally available luxury automatic
climate control switches to air recirculation mode upon detecting increased
pollutant levels in the outside air.
· A touch of a button on the steering wheel is sufficient to
instruct the car radio, CD or cassette player and car phone to obey the
driver's spoken commands by means of the LINGUATRONIC voice control system.
Individual settings can be stored using the steering wheel
Many of these settings are entered with the aid of the new standard-fitted
multifunction steering wheel, which is coupled to the new central display
in the instrument cluster and to the car radio and car phone. The driver
simply has to touch the lower left-hand button in the steering wheel briefly
in order to display the main ”Settings” menu, where more than 50 individual
functions can be programmed under five different submenus – from digital
speed display to automatic door locking once on the move, from automatic
mirror adjustment for parking to the easy exit/entrance feature.
In addition to these individual setting options, the central display
unit provides a whole range of information, messages and data: daily and
total distance traveled, engine oil level, next service due, coolant temperature,
name of radio station when listening to the radio, track number when listening
to tapes or CDs, recommended directions of the navigation system, fault
messages or remaining distance to empty.
The instrument cluster has been redesigned. Instead of the previous
round instruments, three arc-shaped displays indicate the engine revs (left),
speed (middle) and fuel level (right). The telltale and warning lights
are located under the rev counter, inside the middle speedometer segment
and under the fuel gauge. These lights only come on when the ignition is
switched on or if there is a fault – otherwise the instrument panel remains
dark at these points.
The glovebox is three times the size of the outgoing model
The top section of the dashboard includes the instrument cluster cover
and the side and middle ventilation outlets, which have a modern, cylindrical
design that integrates perfectly in the rounded front edge. The lower half
of the dashboard includes the knee bolster on the driver's and front passenger's
side, which is made of a special blend of polymers with a soft foamed film,
and the center console and two-part glovebox that is part of a comprehensive
stowage space concept. With a volume of 8.2 liters and measuring 400 millimeters
wide by 162 millimeters deep, the glovebox is almost three times bigger
than its equivalent in the outgoing model (3.0 liters). Consequently, a
CD changer can now optionally be installed in the upper section of the
glovebox. A compartment for sunglasses or spare spectacles is also built
into the glovebox. The pockets in the interior linings of the driver's
and front passenger's doors provide sufficient space to stow an umbrella,
road maps, an ice scraper and spectacles cases. The capacity of each of
these door pockets is about 3 liters and is therefore double that of the
outgoing model. The cover of the two-part stowage box between the front
seats also serves as a padded armrest, which in the Elegance and Avantgarde
lines as well as in conjunction with THERMATIC or THERMOTRONIC is adjustable
in two tilt angles.
Comfortable, improved spaciousness for all occupants
The new C-Class has the typical comfortable spaciousness of a Mercedes.
The occupants of the front seats have a shoulder room of 1350 millimeters
and an elbow width of 1400 millimeters, representing increases of 11 and
8 millimeters respectively on the equivalent dimensions of the outgoing
model. The comfort of the rear passengers has been improved by extending
the knee-room by 4 millimeters and the elbow room by 12 millimeters. The
rear headroom in models with a sliding sunroof is 948 millimeters –10 millimeters
more than previously.

Measured by the VDA measuring method, the trunk has a capacity of 455
liters – including a stowage space of 45 liters in the handy recess that
Mercedes-Benz provides instead of the traditional spare wheel. This recess
holds not only the on-board toolkit but also the TIREFIT tire repair kit
and the electric air pump that get the driver back on the road in the event
of a flat tire without having to fit a spare wheel
The driver and front passenger of the new C-Class can make themselves
thoroughly comfortable on the newly developed seats that combine modern
design with significant advances, especially in the fields of ergonomics
and operation. Whereas the occupants previously had to adjust the seat
height and backrest reclining angle manually, each of these functions has
now been taken over by two electric motors. All the occupant has to do
is to operate a two-part switch on the outer seat trim, and the seat cushions
and backrest immediately move to the desired position.
A microchip in the ignition key stores individual seat adjustments
Even greater operating convenience is provided by the complete power
adjuster package for all functions of the driver's and front passenger's
seats, available as an option from Mercedes-Benz. In this case, not only
the seat height and backrest angle but also the longitudinal adjustment,
seat cushion angle, head restraint, steering column and exterior rear view
mirrors are adjusted by electric motors. A microchip stores the individual
adjustment data of the driver's seat and transmits it to the electronic
ignition key. Subsequently, as soon as the driver inserts the key in the
ignition starter switch, the seat, head restraint, steering wheel and exterior
rear view mirror automatically move to the desired position.
Compared to the outgoing model of the C-Class, the engineers at the
Mercedes plant in Sindelfingen, Germany, have improved the lateral and
thigh support of the seat cushions. The technical basis for the front seats
is provided by two suspended aluminum shells that can rotate at the front
for the tilt adjustment facility and that rest on two small coil springs
at the rear. Consequently, the seat shells rock on the metal frame and
can perform additional springing and damping functions to supplement the
effect of the foam cushions lodged in the aluminum frames. A comfortable
seat climate is ensured by ventilation holes in the foam cushion, an 8-millimeter
thick coating of rubberized hair and the fabric seat cover, which, due
to its high wool content, has highly active ”breathing” properties.
Split-folding rear seat bench available as an option
For drivers who wish to vary the trunk format of their sedan, Mercedes-Benz
has developed an asymmetrically split rear seat bench that can be folded
down in a few simple steps at a ratio of 1:2. First, the seat cushions
are folded forwards individually or together into a vertical position behind
the front seats. Then the backrests are folded forwards to produce an almost
entirely flat load floor.
Electronically controlled heating system for additional comfort
”Heatmatic” is the name given by Mercedes-Benz engineers to the automatic
heating and ventilation system on board its passenger cars. As the name
indicates, this is a little more than just an ordinary, conventionally
engineered heater: Heatmatic consists of an electronically controlled system
that measures the interior temperature by means of sensors and maintains
it constant at the level desired by the driver and front passenger. This
innovative technology has long been in standard use at Mercedes-Benz and
has now been further developed and improved by Mercedes engineers for the
C-Class. The control panel for the heating and ventilation system is characterized
by a new design that provides a clearly organized disposition of all relevant
functions, namely the 6-speed fan adjustment (previously 4-speed), air
distribution, separate temperature controls for the driver and front passenger,
air recirculation mode, defrost mode and heated rear window.
Furthermore, the number and area of the various outlets in the dashboard
and rear footwell have been increased to provide comfortable – in other
words draft-free – ventilation. This important aspect of draft prevention
was also behind the development of an innovative indirect ventilation system
that has its debut at Mercedes-Benz. An outlet located in the middle of
the dashboard and directed at the windshield distributes cold air over
a wide area and therefore without causing a draft.
Electric heater booster for CDI models
In addition to the standard-fitted Heatmatic system, the diesel models
of the new C-Class are equipped with an additional electrical heating system
to ensure pleasant warmth in the interior. This heater booster is necessary
because although the CDI engines of the new C-Class have the advantage
of consuming very little fuel, due to their high thermal efficiency they
only transfer little heat to the coolant when running at part-throttle.
As a result, the heating effect is less than in a car with a conventional
engine. The additional heating requirement of the CDI models is also supplied
by a water-cooled alternator (190 Amp) that rotates at up to 18000 rpm
when the car is on the move and delivers its waste heat to the coolant.
Humidity sensor and variable compressor for optimum air conditioning
When it comes to air conditioning, Mercedes customers have a choice
with the new C-Class. Two systems are available: the THERMATIC automatic
climate control with automatic fan control and air distribution (standard
in the C270 CDI, C240 and C320 models) and the THERMOTRONIC luxury automatic
climate control with an activated charcoal filter, a sun and pollutant
sensor and many other extra functions. Compared to the outgoing model,
the electronic air conditioning control has been further improved: for
example, two sensors (previously one) are now used to measure the interior
temperature and to supply the system with even more precise data, so that
it can respond even more rapidly to temperature fluctuations.
The newly developed automatic climate control of the C-Class operates
on the same basic principle as many other air conditioning systems – namely
the ”reheat” principle. In other words, even at cold outside temperatures,
the system is in permanent operation and always first cools the incoming
air, thereby drying it so that the windows remain mist-free. The air is
then reheated to the desired temperature. The new feature of this intelligent
circuit is a 3-stage control system that activates the reheat mode as a
function of relative humidity. This feature has been made possible by a
newly developed dew point sensor which supplies the air conditioning microcomputer
with the data required for need-oriented control of the 3-stage reheat
function and ensures that the incoming air is cooled and then reheated
as a function of its actual moisture level. As a result, the air conditioner
operates much more economically than conventional systems.
The new concept has also been made possible by the use of a new refrigerant
compressor with infinitely variable electronic control as a function of
the cooling power actually required. Whereas until now the air conditioning
compressor was engaged or disengaged with the aid of an electromagnetic
clutch, it is now directly connected to the engine by belt drive, so that
it is in constant operation. The infinitely variable control function is
provided by a solenoid valve.
The system stores the individual driver's settings and transfers the
data to the electronic ignition key. This memory function ensures that
the automatic climate control will restart with the desired program on
the next journey.
THERMOTRONIC for luxury automatic climate control like in the S-Class
The newly developed luxury automatic climate control lives up to its
name: it brings S-Class comfort to the C-Class. Examples of this luxury
comfort include:
· Automatic control of temperature and air distribution individually
for the driver's and front passenger's sides;
· Additional sensor signals for sunlight and pollutant levels
in the outside air;
· Standard-fitted activated charcoal filter;
· Clearly organized display for temperature and fan speed;
· Storage of additional individual setting data in the electronic
ignition key;
· Ventilation outlets at the rear.
The new Mercedes-Benz C-Class is the only car in its market segment
to have automatic climate control using sensors for sunlight and pollutant
levels as well as an activated charcoal filter.
Electronics: From COMAND to D2B
· COMAND system for audio, telecommunications and navigation
· LINGUATRONIC voice control system can now also operate the
audio functions
· TeleDiagnosis, the direct link to the customer service adviser
· Dynamic routing using up-to-date traffic information
· Optical fibers for rapid data transmission
All the latest-generation telematics systems are being premiered in
the Mercedes-Benz C-Class. They not only optimize up-to-the-minute
traffic-jam warnings and use all the latest traffic data to guide drivers
”dynamically” to their destination, but also for the first time provide
a direct link to the team of advisers at the Mercedes-Benz Customer Assistance
Center who can give advice in the event of technical queries or organize
breakdown assistance.
With dynamic routing, the navigation system uses the connected car
phone to contact Tegaron Telematics, a joint venture established in Bonn
between DaimlerChrysler and mobile phone company T-Mobil. Tegaron Telematics
analyzes the information from Gesellschaft für Verkehrsdaten, a traffic
data provider that monitors the traffic situation on German autobahns by
means of about 3800 infrared or ultrasonic sensors. Using the Short Message
Service (SMS) of the mobile phone network, Tegaron transmits congestion
warnings to the dynamic navigation system of the new C-Class, which takes
the latest traffic information into account for the individual routing
function and recommends an alternative route in the event of a traffic
jam. As soon as the system calculates an alternative route, a voice in
the loudspeaker announces: ”This route has been computed on the basis of
traffic news,” and the message ”Congestion ahead” appears on the navigation
system display.
Radio Data System transmits digital traffic data to the car
A second possible method of receiving digital traffic data and using
it for individual routing is provided by the Radio Data System (RDS) over
the Traffic Message Channel (TMC). On this channel, radio broadcasters
transmit inaudible signals that the navigation system decodes and evaluates.
These signals contain traffic jam messages that are put together with the
aid of induction loops in the road surface of autobahns or on the basis
of information provided by the police. The information contained in these
messages corresponds to the traffic news of the normal (audible) radio
stations and is free of charge. RDS-TMC is already in operation all over
Europe. Dynamic routing with this technology is currently operational in
Germany, and preparations are also under way to introduce the system in
other European countries.
The system requirement for dynamic routing is the APS navigation system
(Auto Pilot System) developed by Mercedes-Benz. This system guides drivers
automatically to their destination with the aid of GPS (Global Positioning
System) satellites, wheel sensors and digital road maps.
Car radio comprises navigation system and dynamic routing
A choice of two combination units incorporating navigation systems
with the capacity for the modern ”dynamic routing” telematics service is
available for the new C-Class. The Audio 30 APS combines an FM/MW/SW/LW
tuner, CD player and navigation system inside a single housing that is
the size of a conventional car radio. The unit also includes a built-in
4-channel amplifier (4x20 watts), LCD display, GPS tuner and antenna diversity
system, which evaluates the signals from four radio antennas. Radio reception
is based on the two-tuner principle: while one tuner tunes into the radio
station selected by the driver, a second tuner in the background constantly
monitors the reception quality of all receivable transmitters. As a result,
the radio can immediately switch over to another frequency of the desired
station.
In order to reach the desired destination under the guidance of the
APS navigation system, the driver must insert the CD-ROM containing the
digital map in the combination unit when specifying the destination. The
car radio then stores the necessary data of the CD-ROM and starts calculating
the route. At this point, the CD player can again be used to play music
CDs.
COMAND integrates all communications control features
The other system integrating the navigation system and dynamic routing
is the Cockpit Management and Data System – or COMAND for short. This system
was first introduced in late 1998 in the Mercedes S-Class and acts as a
control center for all audio, telematics and telecommunications functions,
namely car radio, CD player, navigation with dynamic routing, CD changer,
sound system, car phone, voice control and TV receiver.
The driver can either operate these functions directly on the COMAND
unit in the center console and read the necessary user messages on the
large color display or else can transmit instructions with the buttons
of the new standard-fitted multifunction steering wheel. These buttons
can be used to control the volume, car radio, CD player, phone and navigation
system display. The central display in the instrument cluster and the information
on the COMAND display in the center console are coupled together but can
also be operated separately. For example, the cockpit display can show
the graphical routing instructions (arrows) of the navigation system while
the front passenger is browsing through the electronic phonebook on the
COMAND screen.
The technology of the integrated navigation system is based on the
same principle as the Audio 30 APS unit. Here too, the CD player can be
used both as a data storage medium for the CD-ROM map and also for playing
audio CDs. However, COMAND provides even more functions and above all is
unique in having a color LCD display. On this display, an additional easy-to-read
map of the area and selected route can be called up by pushbutton. With
the aid of this map and a crosshair cursor, the driver can pinpoint and
program the destination. A TV tuner can be optionally connected.
TELE-AID automatically alerts the emergency services in an accident
The TELE-AID automatic emergency call system is one of the additional
telematics services provided for Mercedes customers. ”Automatic” means
that the system itself emits an SOS call following an accident without
human intervention, to alert the rescue services and guide them to the
accident site. The SOS signal from the car is transmitted by mobile phone
to an emergency call center. The message consists of the following information:
time, vehicle license plate number, vehicle model and precise location.
On the basis of this information, the call center operators immediately
determine the closest emergency service center and forward the call.
Like the navigation system, TELE-AID works with GPS (Global Positioning
System), a system of satellites that send digital direction-finding signals
to the vehicle from their orbit around the earth. Depending on the accident
type, the emergency call system is triggered automatically either by the
standard-fitted crash sensor that is also responsible for activating the
airbags and seat belt emergency tensioning retractors, or by the rollover
sensor. The occupants of the C-Class can also send out the emergency call
message manually by means of a button in the interior of the C-Class. After
the emergency call, TELE-AID automatically permits a connection to the
operations control center of the police.
TeleDiagnosis provides a direct connection to the customer adviser
TeleDiagnosis is the latest telematics service for Mercedes customers
and is making its debut together with the new C-Class. As a basic system
requirement, the sedan must be equipped with TELE-AID. In the event of
a breakdown, the new TeleDiagnosis system establishes contact with the
central Customer Assistance Center (CAC) at the touch of a button. The
customer advisers then speak with the driver by mobile phone and provide
advice and practical support. At the same time, the system automatically
sends all necessary data to the Center: vehicle and engine model, year
of construction, engine temperature, battery voltage, mileage and any stored
fault and warning messages. In addition, the telephone automatically transmits
the car's exact position, so that the service engineers of the closest
Mercedes branch or workshop can be directed as rapidly and accurately as
possible to the breakdown site. In order to establish the voice and data
link to the CAC, all that is required is to press the blue button with
the screwdriver signal on the fixed receiver of the TELE-AID system.
”MB Info” provides information about Mercedes-Benz
By mobile phone and with the aid of the TELE-AID system, Mercedes customers
can also ask the customer advisers general questions and obtain advice
and information on all subjects relating to the car. This new service is
entitled ”MB Info”. The phone number is stored in the electronic phone
book of the car phone and appears on the display with the label ”Info”
after a short initial period in the operating menu. Subsequently a single
press on the call button is enough to establish the toll-free voice connection.
With LINGUATRONIC the car radio does what it is told
The innovative LINGUATRONIC voice operation system that Mercedes-Benz
was the first car manufacturer in the world to develop for the operation
of the car telephone does even more in the new C-Class. Available as an
option, it now not only controls the most important telephone functions
but is also, for the first time, connected to the audio systems. As a result,
a couple of words from the driver are sufficient for the radio to seek
another station automatically, change to the next CD track or switch over
to navigation mode.
With this technology, Mercedes-Benz is providing a further major contribution
to traffic safety, because drivers no longer have to take their hands off
the steering wheel to operate the car phone or audio systems. LINGUATRONIC
therefore relieves the burden on drivers, who can now concentrate fully
on the road, and also considerably improves driver comfort. Only the tone
and volume controls cannot be voice-operated. The heart of the LINGUATRONIC
system is a software package that is programmed with algorithms for voice
recognition and for peculiarities of the human voice. Consequently, the
system can even adjust to the individual speaking style of the relevant
user. For instance, in Germany, it can understand both high German and
local dialects. The system also operates in English, French, Spanish and
Italian.
Data transfer at the speed of light
The transmission of sensor signals, measurement data, information,
music and TV pictures at lightning speed is ensured by three high-capacity
databus systems on board the C-Class. These systems divide the transmission
functions into three sections – interior, drive train/chassis and audio/communication/navigation
– and are interconnected by means of interfaces ("gateways"). The ”Class
C” CAN network for the drive train/chassis section integrates seven control
units. In the ”Class B” network, up to 20 nodes exchange their data. For
the first time, the control unit for the airbags and TELE-AID emergency
call system are also integrated in the network. In total, the on-board
electronic system of the new C-Class controls more than 130 functions by
databus and processes more than 850 different items of information for
this purpose.
In addition to the proven CAN systems, the C-Class also has an optical
system that uses pulses of light to transmit signals. The name of this
system is the ”Domestic Digital Bus”, or ”D2B” for short. Instead of copper
cables, this system uses fiber optic cables made of plastic. In these cables,
measurement data and switching signals can travel at the speed of light.
Consequently, nodes connected to the ”D2B” ring network can transfer much
larger amounts of data in a shorter time than in the CAN bus: up to 5.6
million bits are transmitted per second in the fiber optic cable, representing
a transmission rate some 60 times faster than CAN transmission in the interior
by copper cable. The fiber optic cable therefore carries many more information
units in a comparable time, so that even the data of a music CD can be
transferred with perfect sound quality.
Engines and transmissions: More power under the hood
· State-of-the-art four-cylinder and V6 engines with increased
output
· Torque increased by up to 43 per cent
· Exhaust emissions of all gasoline engines comply with EU-4
standard
· Output of direct-injection diesel engines boosted by up
to 14 per cent
· Six-speed manual transmission for greater driving dynamics
and enhanced comfort
More power, greater torque, lower pollutant emissions – these were the
objectives when it came to developing the engines for the C-Class.
These objectives have been achieved: The new model range kicks off
with seven high-torque power plants which, compared with the corresponding
predecessor models, provide up to 20 per cent more output, with pulling
power boosted by up to 43 per cent.
By increasing engine displacement, Mercedes engineers have obtained
extra torque for the entry-level C 180 and the six-cylinder C 240 model
to make this sedan even more nimble and flexible than the predecessor model,
particularly in the lower engine speed range. High levels of driving enjoyment
and sporty dynamics are also provided by the engine powering the new C
200 KOMPRESSOR, which replaces the previous 2.0 liter engine. Superior
performance and a high level of comfort are among the special features
of the new C 320 range-topper which replaces the previous C 280.
The two four-cylinder models are powered by the proven Mercedes engine
which, in different displacement sizes, is also used in the C-, E-, M-
and V-Classes as well as in CLK models. Engineers at Stuttgart have,
however, refined major engine components and modified them to suit the
installation conditions in the new sedan. In addition, the 2.0 liter
engine of the C 180 was provided with a secondary air-injection system
which significantly boosts the effectiveness of the emission control during
the engine‘s cold-start phase. All in all, more than 150 components
of the Mercedes four-cylinder engine were optimized. For example:
· The cylinder head is characterized by airflow-optimized intake
and exhaust ports with an oval cross-section for greater volumetric efficiency.
A new, more compact combustion chamber design serves the same purpose.
· The inlet camshaft on both four-cylinder engines now features
a special Hall sensor which during cold starting senses the position of
the piston in the first cylinder. As a result a significant improvement
in the starting characteristics of the cold engine is achieved.
· The timing gears now have a special rubber coating which helps
reduce engine running noise.
· A newly developed electric suction-type fan provides the engine
compartment with cold air. It allows the amount of engine cooling
to be fine-tuned in the interests of fuel economy and noise reduction.
· The air ducts and the intake manifold were also modified with
a view to noise reduction. The newly developed broadband resonator
reduces intake noise.
· Modern single spark ignition coils integrated right behind
the cylinder head increase the efficiency of the ignition system.
Other new features include the modern platinum spark plugs which only need
to be replaced every 100,000 kilometers.
· Using a torque interface, a new electronic engine management
system perfects the interaction of engine, transmission and standard-fitted
Electronic Stability Program (ESP®).
The new C 180 offers greater flexibility and greater performance
With the further developed 2.0 liter naturally aspirated engine which
develops 95 kW/129 hp at 5300 rpm, the C 180 typifies the dynamic and agile
character of the new C-Class. The increased displacement and refined
engineering of the four-cylinder unit provide extra flexibility and greater
performance compared with the previous entry-level model. 185 Nm
of torque is available from just 3500 rpm, cutting the time for the
sprint from 60 to 120 km/h in fifth gear to 20.2 seconds or by around six
seconds compared with the predecessor model. Despite the increase
in power output and the approximately 100 kg higher vehicle weight, fuel
consumption of the new C 180 rises by just 0.1 to 9.3 liters per 100 kilometers
(NEDC overall consumption, provisional figure).
C 200 KOMPRESSOR for dynamic driving enjoyment in the two-liter class
The new two-liter compressor engine with 120 kW/163 hp provides a dynamic
driving experience which is pretty rare in this displacement class.
In conjunction with its excellent value for money, the C 200 KOMPRESSOR
has all the right ingredients to assume an outstanding position within
its market segment. Fitted with a belt-driven supercharger, this power
plant matches the performance and torque characteristics of a larger six-cylinder
engine. With a hefty 230 Nm, the C 200 KOMPRESSOR races from 60 to
120 km/h in just 15.1 seconds (in fifth gear). This sedan requires
a mere 9.3 seconds for the sprint from rest to 100 km/h. These remarkable
performance and torque values do not conflict with the engine designers’
commitment to reduce fuel consumption further. On the contrary: compared
with the outgoing C 200, which developed about 20 per cent less output
and torque, the new C 200 KOMPRESSOR uses only 9.5 liters of gasoline per
100 kilometers, or a mere 0.1 liters more (NEDC overall consumption). Together
with specialists from the Eaton company, Stuttgart engineers developed
the compressor further and optimized countless features which translate
into audible progress. The power plant under the hood of the C 200
KOMPRESSOR features new engine mounts which make the use of an electro-magnetic
coupling between the engine and the charger superfluous. Thanks to
this new mounting technology, the compressor is much quieter in operation.
C 240 with increased engine displacement for improved dynamism
Mercedes engineers have increased the cylinder diameter of the V6 engine
inside the C 240 from 83.2 to 89.9 millimeters, ensuring that a total displacement
of 2597 cubic centimeters is now available. While power output remains
unchanged (125 kW/170 hp), this measure actually provides a torque increase
of almost seven per cent: the six-cylinder unit now develops 240 Nm at
4500 rpm. It is remarkable how these improved engine characteristics
in conjunction with the good aerodynamics of the new C-Class affect driving
performance: the new C 240 requires exactly 16.4 seconds for the sprint
from 60 to 120 km/h and is thus 5.7 seconds quicker than the predecessor
model with the same number of horses under the hood.
C-Class with 3.2 liter V6 power plant for the first time
The new C-Class offers even greater driving fun when equipped with
the powerful 3.2 liter engine, which is regarded as one of the most torquey
power plants in its displacement class. In the C 320, Mercedes-Benz
for the first time combines the visual and technical dynamics of the new
model with a performance potential matched by few other automobiles in
this market segment. Its 160 kW/218 hp and 310 Nm propel the new
C 320 from rest to 100 km/h in just 7.8 seconds. The data and measured

All gasoline engines comply with the strict EU-4 exhaust limits
Mercedes-Benz has developed a sophisticated emission control system
to meet the strict exhaust limits of the European EU-4 Directive and the
American ULEV (Ultra Low Emission Vehicles) regulations. This consists
mainly of an air-gap-insulated exhaust manifold, bulkhead and underbody
catalytic converters as well as an onboard diagnostics system comprising
four oxygen sensors. Exhaust emissions measured in accordance with
the EU-4 Directive are 1.0 g/km of carbon monoxide, 0.1 g/km of hydrocarbons
and a mere 0.08 g/km of nitrogen oxides – i.e. they are up to 56 per cent
lower than under the EU-3 Directive which is currently in force.
Moreover, the high quality of these systems ensures that these low emissions
remain constant over a covered distance of at least 80,000 kilometers.
German buyers of a gasoline model from the new C-Class by Mercedes-Benz
benefit from these exemplary exhaust values in that they receive a one-off
tax credit of 600 marks (if first registration occurs before December 31st
2004), with subsequent motor vehicle tax charged at the reduced rate of
ten marks per 100 cc engine displacement.
New CDI engines develop up to 43 per cent more torque
The acronym CDI now adorns the trunk lid on all diesel sedans of the
new Mercedes-Benz C-Class. It is synonymous with the most advanced
technology: fuel injection which employs the common-rail principle plus
pilot injection plus four-valves-per-cylinder technology plus turbocharger
plus intercooling. The result of this diesel formula guarantees high torque,
exemplary agility and low fuel consumption – the ideal prerequisites for
unspoiled driving enjoyment.
Compared with the predecessor models, the three diesel engines for
the new C-Class offer up to 14 per cent more power output and up to 43
per cent more torque. This is mainly due to the use of the VNT charger
(Variable Nozzle Turbine). The adjustable position of the guide vanes
inside the turbocharger ensures optimum exhaust gas energy at any engine
speed. In the lower rev range in particular the effect is that of
a quicker build-up of charge pressure, improved volumetric efficiency and
hence greater torque.
With its common rail direct injection Mercedes-Benz has achieved considerable
advances compared with the earlier pre-chamber engines – not least in the
areas of driving and noise comfort. Further engineering features particular
to the CDI engines in the new Mercedes-Benz C-Class include:
· The aluminum cylinder head with two spiral induction ports,
one of which has been optimized for swirl and the other for volumetric
flow. This leads to an optimum fuel and intake air mixture particularly
under part-throttle conditions.
· The intake system with a hot film air mass sensor which permits
an exact analysis of the air mass taken in. This provides the micro
computer which is responsible for engine management with precise data.
It is thus capable of controlling exhaust gas recirculation in accordance
with engine load and speed.
· The mixing chamber with an integrated exhaust gas recirculation
valve where fresh and exhaust air combine in a computer-calculated ratio.
The valve is vacuum-operated via an electro-pneumatic converter.
· The intake module, which upstream of each cylinder at first
features just one port before developing into a two-port system that takes
on specific functions. While one of them is used for swirling the
fuel-air mixture, the second one ensures adequate cylinder charging when
the air flow is high. Under part-throttle this port is, however,
closed by electrically operated flaps. This ensures that swirl inside
the cylinders is increased further, producing more complete combustion.
· Pilot injection, which helps significantly to reduce the noise
level of direct-injection diesel engines. A few milliseconds before
the actual fuel injection occurs, a small amount of diesel is pre-injected
into the cylinder. This ignites immediately, thereby preheating the
combustion chamber. As a result, the fuel ignites more rapidly, while
pressure and temperature do not rise so abruptly.
The C 220 CDI offers a powerful 315 Newton meters of torque
Thanks to the power output hike from 75 kW/102 hp to 85 kW/115 hp and
the extra torque of around 6.4 per cent, the new C 200 CDI offers even
greater diesel driving pleasure. Particularly remarkable is the engine’s
enhanced flexibility which propels the sedan in 18.0 seconds from 60 to
120 km/h (in fifth gear) – taking 7.2 seconds less than the outgoing model.
With its 105 kW/143 hp and the powerful torque of 315 Nm, the new C 220
CDI even matches the more powerful C 200 KOMPRESSOR in terms of pulling
power. The diesel sedan sprints from 60 to 120 km/h in just 15.0
seconds and achieves a maximum speed of 220 km/h. The fuel consumption
of the C 220 CDI, is only 6.2 liters per 100 kilometers (NEDC overall consumption).
The new C 270 CDI uses 14 per cent less fuel
The new C 270 CDI is a particularly agile and dynamic automobile which
is superior to its predecessor model in every respect. With a power
output up more than 13 per cent the new model uses almost 14 per cent less
fuel than the outgoing C 250 TURBODIESEL: a mere 6.9 liters per 100 kilometers
(NEDC overall consumption, provisional figure). The data of the modern

Electronic monitoring of engine oil level
The Active Service System ASSYST is part of the standard equipment
of all engines of the new C-Class. On the basis of sensor-derived
data, ASSYST calculates the actual load on the engine oil and works out
a need-oriented servicing schedule for the engine. This means that
oil change intervals can be increased, depending on the driving style and
engine load, to up to 30,000 kilometers on gasoline models and up to 40,000
kilometers on the new C-Class diesel sedans.
The advanced electronics that provide ASSYST with the necessary sensor
data also make life easier for the driver: on the new Mercedes-Benz C-Class
it is no longer necessary to check the oil level manually using a dipstick.
Instead it is sufficient to press a button on the multi-function steering
wheel for the requested information to be shown on the central display
of the instrument cluster. While the car is on the move, the system
works automatically and only informs the driver if the oil has reached
a critical level. Only on the four-cylinder models C 180 and C 200
KOMPRESSOR is it possible to manually check the oil level.
Six speeds as standard
With the exception of the C 320 all models of the new Mercedes-Benz
C-Class are equipped as standard with the newly developed six-speed manual
transmission. The six-cylinder range-topper features the five-speed
automatic transmission as standard. The six-speed manual gearbox
was developed to offer drivers even greater comfort while at the same time
further reducing fuel consumption. The new C-Class reaches its top speed
in sixth gear.
The gear-changing effort is greatly reduced thanks to the use of sophisticated
multiple-cone synchromesh. Engineers have paid particular attention
to easy diagonal gear changes, i.e. when changing up from second into third.
Compared with the previous five-speed gearbox, shift effort has been reduced
by about 25 per cent. At the same time, shorter shift travel has
reduced gear-changing time by an average of 0.3 seconds – all in the interests
of an agile and dynamic driving style which is made possible by the torquey
engines of the new C-Class.
Automatic transmission offers even more convenience thanks to one-touch
gearshift
Life is made even easier for drivers who opt for the modern five-speed
automatic transmission, particularly as this component now offers even
greater convenience. This is ensured by the one-touch gearshift which
Mercedes-Benz first introduced in 1998 on the new S-Class. Thanks
to this technology, the individual driving ranges can be selected in position
D by a slight movement of the selector lever to the left or right.
Moving it to the left means changing down; moving the lever to the right
engages a higher driving range. If the driver moves the selector
lever to the left for longer, the driving range changes to the gear selected
by the automatic transmission.

Chassis: Dynamic handling as standard
· Further advances in handling, safety and comfort
· New three-link system at the front, proven multi-link independent
suspension axle at the rear
· New disk brakes with large performance reserves
· Latest driving safety systems fitted as standard
Mercedes-Benz engineers have spared no effort in upgrading existing
or designing new axles, steering and brakes in order to surpass the high
standards of the outgoing model yet again. The advances made are immediately
noticeable: exemplary agility, precise straight-line stability, extremely
accurate steering, excellent rolling comfort, effective braking performance
and safe handling even when pushed to the limit.
The agile handling of the C-class is attributable to a substantial
degree to the new front-axle design. Wheel location, comfort and steering
response are enhanced by a design which Mercedes-Benz are using for the
first time in this form: a three-link axle with McPherson struts and rack-and-pinion
steering. In the interests of even better suspension kinematics the
engineers have replaced the lower wishbones used to date by two individual
link elements which function as torque struts and transverse links. In
addition to more precise wheel location, the main benefit of this design
is that it is better able to compensate for vibrations resulting from tire
imbalance or brake force fluctuations than rigid wishbones. The third
element in the front-axle suspension is the track rod, which connects the
transverse steering gear to the wheels. The spring struts also have a multiple
role since they not only spring and damp the axle, but also actively assist
with locating the front wheels. The spring struts consist of cylindrical
coil springs, twin-tube dampers and large head bearings. The standard-fitted
torsion bar stabilizer is connected to the spring struts by a linkage.
The wheelbase has been extended by 25 millimeters
The wheelbase of the new C-Class is 2715 millimeters, and therefore
25 millimeters longer than its predecessor. The track widths of the front
and rear axles have also increased - at the front by six millimeters and
at the rear by twelve millimeters. However, the sedan’s turning circle,
at 10.76 meters, has remained almost unchanged.

High-precision steering with modern rack-and-pinion principle
There are several reasons for using rack-and-pinion steering instead
of the recirculating ball steering system used before. The most important
was undoubtedly the more immediate response, which is more in line with
the dynamic character of the new C-Class. Furthermore, locating the steering
gear in front of the wheel center plane results in safe understeering performance
when cornering. However, the new system also offers benefits in certain
aspects of passenger protection and lightweight construction: whereas the
recirculating ball steering gear forms a solid block which absorbs no energy
in the event of a front impact, the rack-and-pinion steering can be transversely
mounted on the deformable aluminum bracket and, therefore, does not impede
the energy absorption process. And because this system has no need of supplementary
components such as a Pitman arm, steering rod, idler arm and reinforcing
plate, it is some 4.5 kilograms lighter than the recirculating ball steering
gear of the outgoing model.
As previously, a standard-fitted servo-system reduces the steering
effort. A new feature, however, is the easy-operation, speed-sensitive
steering, which Mercedes-Benz are also offering as an option for the first
time in the C-Class. Its effect is particularly noticeable at speeds below
100 km/h and reduces the steering moment as a function of speed. Thanks
to an electronically controlled rotary slide valve which regulates the
power assistance, the steering effort in urban traffic is reduced by up
to 50 percent compared with conventional power steering, with the result
that parking is particularly easy with speed-sensitive steering.
Proven multi-link independent-suspension system has been retuned
The multi-link independent-suspension axle, which is still unsurpassed
in many respects, made its first appearance when the Mercedes-Benz 190
went into production in 1983. This patented axle design therefore also
remains in use in the new C-Class where, in conjunction with the new front
axle, the extended wheelbase and the standard-fitted Electronic Stability
Program (ESP®), it ensures a level of safety, handling and comfort
which has never been available before in this vehicle class. The
Mercedes engineers have thoroughly revamped the design of the track rods,
hub carriers and rear-axle subframe. New kinematics and elastokinematics,
based mainly on the use of optimized bearings, ensure even better vibration
properties and reinforce the sedan’s understeering self-steer effect, which
also guarantees a high level of handling safety. All the engine versions
of the new C-Class, with the exception of the C 180, have a torsion bar
stabilizer on the rear axle. It is directly attached to the vehicle body.
Springing and damping of the rear axle are provided by coil springs and
single-tube gas dampers with enlarged rubber mountings.
Drivers who prefer a particularly sporty driving style can order their
C-Class with sports suspension, in which the vehicle body is lowered by
15 millimeters at the front and rear axles, as an optional extra for all
lines and engine versions. The overall travel is 20 millimeters shorter
on the front axle and ten millimeters shorter on the rear axle with the
sports suspension tuning than in sedans with standard suspension. The spring
rates are up to 21 percent higher. Furthermore, the ”Sports Suspension”
option also contains 16-inch light alloy wheels and 225/50 R 16 wide tires
for all models.
High-performance braking system can cope with any situation
Mercedes engineers have again made significant advances in the field
of brake systems too – particularly in terms of braking performance and
braking comfort. Thus, all engine versions are now manufactured with ventilated
front disk brakes whose diameter has been increased to 288 millimeters
and thickness to 25 millimeters on the four-cylinder gasoline and diesel
engines. In the C 240, C 320 and C 270 CDI sedans the diameter of the front
disk brakes is 300 millimeters, while the disk thickness measures 28 millimeters.
Thanks to their large size and the newly developed brake calipers made
of high-strength nodular cast iron the sliding-caliper disk brakes on the
front axle of the new C-Class feature above-average performance reserves
even under heavy loads.
Another new feature is the narrow stud-like castings in the ventilation
ducts of the brake disks, where they replace the cooling fins used previously.
The special design of these components, which link the two friction ring
halves of a brake disk, ensures an optimal flow of cooling air and therefore
increases the gray cast iron disks’ shape retention under thermal load.
In concrete terms this means the annoyance of brake judder, which frequently
occurs because of deformed brake disks, is effectively prevented by this
modern system. The rear axle of the new C-Class is fitted with solid
disk brakes with a diameter of 278 millimeters (C 240 and C 320: 290 millimeters)
to ensure safe deceleration. Here the Mercedes engineers use fixed-caliper
brakes with a twin-piston system. The new aluminum brake booster
for the C-Class is a uniform 7/8 inch for all engine variants – which means
that it is approx. 15 percent more powerful than in the outgoing model.
Advanced control systems for optimum safety
Like all the latest Mercedes passenger cars, the new C-Class, too,
is fitted with the world’s best and most efficient handling safety systems
– as standard. They reduce the risk of skidding when cornering, keep the
sedan safely on course when braking, ensure improved accelerating from
rest on slippery surfaces and shorten stopping distances in emergencies.
This efficient technology is an important element of the safety concept
of the Mercedes-Benz brand (see also on page 36) and actively helps to
prevent road accidents:
· Electronic Stability Program (ESP®): Thanks to a variety
of sensor signals, the Electronic Stability Program detects hazards far
sooner and faster than even the most experienced driver. The system can
therefore intervene in a highly controlled fashion to stabilize the vehicle.
While the car is in motion, the ESP® computer constantly compares the
car’s actual handling with the calculated set points. If the car diverges
from the safe ”ideal line”, ESP® intervenes extremely rapidly and returns
the car to the right line in two ways: by delivering precisely gauged braking
pulses to one or more wheels and by reducing the engine torque. ESP®
will also stabilize the C-Class in the event of skidding caused by extreme
driving maneuvers, ice, wet, gravel or other unfavorable road conditions.
The latest ESP® generation is particularly impressive: it works extremely
smoothly because of its almost imperceptible responsiveness. It is this
fine tuning in particular that demonstrates the great experience which
Mercedes’ engineers have as inventors of this innovative system.
· Anti-lock braking system: ABS prevents the wheels from locking
when braking in an emergency and works just as reliably on dry asphalt
as on wet or icy roads.
· Acceleration skid control: The sensor signals provided by
the anti-lock braking system are also available to the acceleration skid
control system (ASR), which is also part of the Electronic Stability Program
(ESP®). ASR helps to prevent wheel spin at the drive wheels when accelerating
from rest or in motion or for general driving – in the event of ice, for
example.
· Brake Assist: This system, which Mercedes-Benz developed to
reduce stopping distances in emergencies, is also one of the functions
included in ESP® in the C-Class. Brake Assist (BAS) springs into action
if the driver brakes too hesitantly or gently in critical situations. In
such cases the system automatically generates the maximum brake boost within
fractions of a second, thereby substantially shortening the car’s stopping
distance quite considerably by up to 45 per cent.
The range of wheels also meets the wishes of sporty drivers
The C 180, C 200 KOMPRESSOR, C 200 CDI and C 220 CDI in the Classic
and Elegance lines are shod as standard with 195/65 R 15 wide tires on
6 J x 15 wheels. The Avantgarde line stands out with its standard-fitted
16-inch wheels and 205/55 R 16 tires. This combination is also the standard
equipment for the five- and six-cylinder models (C 240, C 320 and C 270
CDI) in all the lines.
The C-Class looks even more dynamic with the sports suspension in conjunction
with the ”Light alloy wheels in 5-double-spoke design” option. 225/50 R
16 tires are fitted to 7 J x 16 wheels on the front axle and to even wider
8 J x 16 light alloy wheels on the rear axle – which perfectly underlines
the car’s sporty handling. It is also possible to have mixed 17-inch
tires on attractive AMG light alloy wheels in conjunction with the sports
suspension: 225/45 R 17 (7.5 J x 17) at the front and 245/40 R 17 (8.5
J x 17) at the rear.
