The 2008 Chevrolet Corvette gets a new base engine with more power. These two-seat sports cars are available as hatchback coupes and convertibles with a manual folding soft top. Base and Indy Pace Car Replica models have a new 430-hp 6.2-liter V8 engine that replaces a 400-hp 6.0-liter V8. An available "dual-mode" exhaust system increases horsepower to 436. They're available with a 6-speed manual or a 6-speed automatic transmission. The high-performance Corvette Z06 and 427 Limited models are available as coupes only and come with a 505-hp 7.0-liter V8 and mandatory 6-speed manual transmission. They also have specific suspension tuning, tires, and brakes. Available safety features include ABS, traction control, antiskid system, and side airbags that protect head and torso. Base models are available with GM's Magnetic Selective Ride Control that automatically adjusts firmness within two driver-selectable modes. Also optional on base Corvettes is a high-performance Z51 package that has a firmer, nonadjustable suspension.
