Internal combustion engines will perhaps go through impressive changes in the near future; as it has been said, more so in the next 10 years than in the past century. Unfortunately, the future didn't make itself present at the show, only some marvels of the present did.

GM

• Chevrolet Vortec 4.2l I6

Close up view of the variable phase intake camshaft.

• Maserati 4.2l V8

Cross-section view where it is possible to notice its racing-style details, such as dry sump and wet cylinder sleeves.

• Oldsmobile Aurora 4.0 V8

The NorthStar-derived engine, but with a smaller displacement. The current all-time wining engine at Formula Indy was based on it.

• Subaru 3.0 H6

The horizontal configuration lends itself to a very smooth and short engine, as is the case of this beatifully designed Subaru engine. Also of notice, its dual stage intake resonance system.

VW

• ^{4.0 W8}

By far the weirdest V8 ever. Although compact, it requires exotic materials to keep its weight down. Notice the two balance shafts below the cranckshaft and that the pistons heads and intake manifold length are not the same for all cylinders: those in the inner cylinders are rather different from those in the outer ones.
