2008 Corvette C6

The changes include everything from a completely new, larger and more powerful V-8 engine to refinements in driving characteristics that solidify the Corvette s position as the premier American sports car and further the argument that one of the world’s best. There are also many exterior and interior refinements that raise the Corvette’s luxury status and enhance s the feeling of craftsmanship.

Corvette is an uncompromising sports car that rewards its owners with impeccable SPD and great comfort and power, said Ed Peper, Chevrolet General Manager. The changes and improvements to the 2008 Corvette reflect continual improvements that speak Chevrolet and tireless commitment to building the best sports car and nearly 55 years of experience, the Corvette just keeps getting better and better. 08 again for the 505-horsepower Corvette Z06, an American super car that has won fans, journalists and racers around the world for its balance of track-bred performance, daily driving civility and value.

Here sa look at the different and improved features for 08 Corvette models:

Another engine, 6.2L LS3 small-block V-8 is the standard engine in Coupe and Convertible models. It is rated at 430 hp (321 kW) and 424 lb.-ft. of TQ (586 Nm) with the standard exhaust system, with various optional two-mode exhaust system, increasing power to 436 horses / 325 kW and 428 lb.-ft. / 592 Nm. As a result, the standard Corvette is true supercar, capable of 190 mph. The LS3 with the six-speed paddle-shift automatic is the fastest automatic-equipped Corvette ever, with 0-60 mph capability of 4.3 seconds.

This iteration of the several floors of small-block family features a revised, larger bore cyl. block 4.06-inch / 103.25 mm vs. the previous 6.0L s 4.00-inch / 101.62 mm bores high-flow, LS7/L92-style cyl. heads, larger diameter slugs, revised camshaft and camshaft timing; revised valves with offset intake rocker arms, high-flow intake manifold, higher flow fuel injectors from the Z06 s LS7 engine and a new engine beauty cover.

The LS3 features an aluminum cylinder block with cast iron cyl. liners. Besides the larger holes, contributing to a 376-cid displacement, the block casting also features revisions and machining in the bulkheads to enhance its strength and improved bay to bay breathing. But while the bore of the 6.2L engine is increased compared with the previous 6.0L engine, the engine continues to blow s 3.62 inch (92 millimeters). Slugs for the larger 6.2L engine also are different and serve for the high-rpm performance capability.

Breathing for the different 6.2L engine is achieved through new, high-flow cil. heads. She again based on the large port / large valve pattern found on the LS7 engine and other GM L92 engines, with a larger capacity, straighter intake ports. The pattern optimizes intake flow to the combustion chamber and the tent doors are also made for a better flow.

To complement the pattern of the larger port heads are proportionately large valves. The intake valve size alone increases from 2.00 inches (50.8 millimeters) to 2.16 inches (55 mm) an increase of nearly 9 percent. The intake valves feature lightweight hollow stems, which the engine s 6600-rpm capabilities. The exh valves are large, measuring 1.60 inches (40.4 millimeters) in diameter.

To fit large engine valves and enable more direct intake port flow, the intake-side rocker arms are offset 6 mm between the valve tip and the push rod. Operation of the valves is a new camshaft, with intake-side lobes more than a 5-percent percent in increase in lift, from 0.521 inch to 0.551 inch (13.25 millimeters to 14 millimeters). exh-lift of the valves remains unchanged from the LS2. The camshaft timing was revised to optimize performance with the higher-lift intake cam profile.
