For 2008, engineers beefed up the performance of the C6-1/2 generation Corvette with an all-new 6.2-liter V-8 engine capable of 0-60 mph in 4.3 seconds, according to Chevrolet. In addition, there's a new 2.73 performance axle for automatic transmission models, two new exterior colors, interior trim refinements, and OnStar, XM satellite radio and other previously optional equipment now standard in all Corvette models.
The 2008 Chevrolet Corvette is available in three models: coupe, convertible and ZO6. The list of standard equipment on the coupe and convertible includes split-spoke cast aluminum wheels; improved steering; new keyless access remote key fob with integrated key; interior trim enhancements including brushed aluminum accents; auto-dimming mirrors with compass; and two new premium exterior colors-Jetstream Blue Metallic Tintcoat and Crystal Red Metallic Tintcoat. Available options include the Z51 performance package; 2.73 performance axle with 6-speed automatic paddle shift (included in Z51 package); polished forged aluminum wheels; custom leather-wrapped interior package in new colors of Linen and Sienna; and a dual-mode performance exhaust system.
Standard equipment on the ZO6 model includes the 7.0-liter LS7 V-8 engine; forged steel main bearing caps and crankshaft; titanium connecting rods; cast aluminum flat-top pistons; unique cylinder block; and racing-derived aluminum cylinder heads with titanium-filled intake valves and sodium-filled exhaust valves. ZO6 options include a Bose audio system with an in-dash 6-disc CD changer; polished chrome or Competition Gray wheels; side-impact air bags; telescoping heated steering wheel; heated seats; and a navigation system with GPS and universal home remote.
The all-new 6.2-liter LS3 V-8 engine, which features an increase in displacement of .2 liters from the 6.0-liter 2007 engine, is standard on the 2008 Corvette coupe and convertible and delivers 430 hp at 5900 rpm and 424 lb.-ft. of torque at 4600 rpm. With the optional new dual-mode exhaust system, power output increases to 436 hp at 5900 rpm and 428 lb.-ft. of torque at 4600 rpm. Other new engine features in the 2008 Corvette include an enhanced valvetrain, and new high-flow intake manifold and cylinder head. The new models offer improved manual transmission shift effort and quicker 6-speed automatic shift times as well as a new 2.73 performance axle ratio available with the automatic transmission. There are virtually no changes to the 2008 Corvette ZO6, which features a 7.0-liter LS7 V-8 engine that delivers 505 hp at 6300 rpm and 470 lb.-ft. of torque at 4800 rpm. EPA fuel economy estimates for the 6.2-liter 6-speed automatic V-8 are 15 mpg city/25 mpg highway; the 6.2-liter 6-speed manual transmission V-8 model gets 16 mpg city/26 mpg highway; and the 7.0-liter V-8 ZO6 is estimated at 15 mpg city/24 mpg highway.
The 2008 Chevrolet Corvette has not been rated by the National Highway Traffic Safety Administration (NHTSA) for front or side-impact crash tests or for rollover tests. However, all 2008 Corvette models have standard driver and right front passenger frontal air bags. Side-impact air bags are standard on the convertible and available on coupe and ZO6 models. Other standard safety features include: active handling, including traction control and anti-lock brakes; run-flat Goodyear extended mobility tires; and Xenon high-intensity discharge headlamps. OnStar with voice-activated turn-by-turn navigation is available on all three models.
Other high-tech features include auto-dimming mirrors with compass; three suspension choices (standard, Magnetic Selective Ride Control, and Z51 performance package); XM satellite radio; full-function OnStar system and available voice-activated onboard navigation system; and three standard dynamic chassis control systems (anti-lock braking, traction control and Active Handling). An iPod/MP3 jack is included on all sound systems except in models equipped with a navigation system; those models offer Personal Audio Link as a dealer-installed accessory.
