The CERV III made its debut at the 1990 Detroit International Auto Show. It was fully operational, more of an engineering project than a design project. It used a prototype of the production ZR1's 5.7 liter aluminum block engine. It was twin turbocharged to achieve 650 hp. The engine was mounted sideways in the chassis with a six speed automatic transaxle. The car had 4-wheel drive, with two centrally located bevel gear sets distributing power to the drive shafts. Front to rear torque split was determined by a computer- controlled hydrostatic device that worked in conjunction with the center differential.
The CERV III weighed 3400 lbs. To cut the weight, the backbone was made of carbon fiber. The backbone itself weighed only 38 lbs. Some titanium was used, as well as aluminum castings. The drive shaft to the front wheels was carbon fiber, as were the eight brake rotors, two per wheel. The body was a mix of carbon fiber, Kevlar, Nomex and aluminum honeycomb. The wheels were cast magnesium. The CERV III h...
