Chevrolet Corvette C5-R

The Chevrolet Corvette C5-R is a grand touring racing car built by Pratt Miller for Chevrolet to contest endurance racing, based on the fifth generation Corvette but designed purely for competition. General Motors wanted to show off the new Corvette with a factory team after years of refusing support, and it chose Pratt Miller of Michigan to build the cars and run the team, with a debut in 1999. The first cars used a 6.0 litre V8 derived from the road car LS1, soon replaced by a 7.0 litre unit built by Katech. Eleven chassis were built between 1998 and 2004, and a twelfth frame served as a test mule for the C6.R. The C5-R won at Daytona, Sebring and Le Mans and took American Le Mans Series titles before the Corvette C6.R replaced it in 2005.
