Get comfortable. There's so much new and exciting with the 2008 Corvette that you'll want to grab a hot drink, sidle up to your computer screen and absorb all the details.
The changes involve everything from an all-new, larger and more powerful V8 engine to refinements in driving characteristics that solidify the Corvette's position as the preeminent American sports car - and further the argument that it is one of the world's best. There are also a host of exterior and interior refinements that raise the Corvette's luxury status and enhance the feeling of craftsmanship.
Engine
A new, 6.2L LS3 small-block V-8 is the standard engine in Coupe and Convertible models. It is rated at 430 horsepower and 424 lb-ft of torque with the standard exhaust system; with the new, optional two-mode exhaust system, power ratings increase to 436 horses and 428 lb-ft. 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 new iteration of the storied small-block family features a revised, larger-bore cylinder 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 cylinder heads; larger-diameter pistons; revised camshaft and camshaft timing; revised valvetrain with offset intake rocker arms; high-flow intake manifold; high-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 cylinder liners. In addition to its larger bores, which help create a 376-cubic-inch displacement, the block casting also features revisions and machining in the bulkheads that enhance its strength and improved bay to bay breathing. But while the bore of the 6.2L engine is increased when compared with the previous 6.0L engine, the engine's stroke remains at 3.62 inches (92 mm). The pistons for the larger 6.2L engine also are new and are designed for its high-rpm performance capability.
Exhaust System
Optional on '08 Coupe and Convertible models is a new, two-mode performance exhaust system. Similar in design and function to the system used on the Z06, the dual-mode exhaust uses vacuum-actuated outlet valves, which control engine noise during low-load operation, but open for maximum performance during high-load operation. It is not identical to the Z06 system; the Coupe/Convertible uses a 2.5-inch-diameter exhaust, while the Z06 uses a three-inch system.
With the new, dual-mode performance exhaust, power output for Coupe/Convertible rises from 430 horsepower and 424 lb-ft of torque to 436 horses and 428 lb-ft. This system gives the Corvette a more aggressive exhaust sound character that will appeal to performance enthusiasts.
Wheels
Corvette Coupe and Convertible models come with a new split-spoke wheel design for '08. The design was introduced on the limited-edition '07 Indianapolis 500 Pace Car replicas with a Sterling Silver finish. The standard 18-inch front wheels and 19-inch rear wheels feature a Sparkle Silver finish, with a Competition Gray version optional.
Also new is a distinctive, performance-oriented forged aluminum wheel for Coupe and Convertible. It comes in a polished finish.
Corvette design and interior details
Dramatic fender forms and exposed headlamps combine with the grille to create a strong visual identity for the Corvette, while the tapered rear deck and fascia improve high-speed performance. The lean rear design sports round taillamps and center-exit exhaust. The fixed Xenon high-intensity discharge headlamps provide superior lighting performance. With a 0.286 coefficient of drag, the Coupe models are the most aerodynamic Corvettes ever.
Corvette's interior is inspired by the car's dual-cockpit heritage. High-quality materials, craftsmanship and functionality help deliver premium quality meant to enhance performance driving. The instrument panel and doors are covered with cast-skin foam-in-place trim that looks like a leather-wrapped, padded panel. It is warm and inviting and has double the life of conventional trim materials.
