Truly an American supercar that brings the technology and engineering refinement of carbon-fiber, ceramics and electronics together in a distinctive design that works to deliver the most powerful and fastest automobile ever produced by General Motors.

These are very special cars, starting with the LS9 6.2 liter, supercharged V-8 that produces over 600 horsepower and delivered through a six-speed transaxle. At the time of introduction, the project manager was claiming that it would have 100-hp per liter helped by the new, four-lobed Roots type, intercooled supercharger. Low three seconds times are attainable in the 0-60 miles per hour sprint. The speedometer has a reading of 220 mph and you can monitor the supercharger with a boost gauge. The suspension has been designed and tested to log over 1g on the skid pad to make this one of the best handling cars in the world. Stopping distances are just as impressive, courtesy of huge carbon-ceramic, ventilated rotors.

This rare Corvette supercar is finished in Cyber Gray, with a two-tone black and grey leather interior and a six-speed manual transmission. This ZR1 is fully loaded with options including heated seats, in-dash CD, DVD navigation, Bose stereo, memory package, universal home remote, luggage shade, steering-wheel mounted radio controls, leather-wrapped steering wheel, Bluetooth, OnStar, dual-zone climate control, and the heads-up display. The car is fitted with 19-inch front and 20-inch rear chrome aluminum wheels. Carbon fiber is used for weight, strength and style with the hood, roof panel, roof bow, side-skirts and front splitter. This handsome, all business ZR1 has covered a mere 543 miles and is presented as when new.
