The Chevrolet Corvette (C6) is the sixth generation of the Corvette sports car that was produced by Chevrolet division of General Motors for the 2005 to 2013 model years. It is the first Corvette with exposed headlamps (as opposed to hidden headlamps) since the 1962 model. Production variants include the Z06, ZR1, Grand Sport, and 427 Convertible. Racing variants include the C6.R, an American Le Mans Series GT1 championship and 24 Hours of Le Mans GTE-Pro winner. Overview The Corvette C6 featured new bodywork with exposed headlamps, revised suspension geometry, a larger passenger compartment, a larger V8 engine and a higher level of refinement. It is 5.1 inches (13 cm) shorter than the C5, but the wheelbase was increased by 1.2 inches (3 cm). It is also one inch (2.5 cm) narrower. The new LS2 engine has a power output of at 6,000 rpm and of torque at 4,400 rpm. Like the C5, the Corvette C6's suspension consisted of independent unequal-length double wishbones with transverse fiberglass mono-leaf springs and optional magnetorheological dampers. With an automatic transmission, the Corvette achieves / mpg (city/highway) of fuel economy; the manual-transmission model gets / mpg of fuel economy. The Corvette's manual transmission is fitted with Computer Aided Gear Shifting (CAGS), obligating the driver to shift from 1st gear directly to the 4th gear when operating at lower RPM. This boosts the EPA's derived fuel economy thus allowing the buyer to avoid paying the "gas guzzler" tax. GM badges were added to the car in 2006. Beginning with the 2008 model year, the Corvette received a new engine, the LS3. With displacement increased to , power was increased to at 6,500 rpm and of torque at 4,600 rpm, or and with the optional vacuum actuated valve exhaust. The previous Tremec T56 transmission on manual Corvettes was replaced with a new version, the TR6060, in the 2008 model year. Manual Corvette models now had improved shift linkage; the automatic model was set up for quicker shifts, and (according to Chevrolet) accelerates from 0 to in 4.0 seconds, faster than any other production automatic Corvette model. From 2008 onward, the steering was revised for improved feel and the wheels were updated to a new five-spoke design. The last Corvette C6, a white 427 convertible, was completed on February 28, 2013.
