Pratt & Miller Engineering and Fabrication, also known as Corvette Racing is an automotive company formed by Gary Pratt and Jim Miller in 1989.
Based in New Hudson, Michigan, they have been one of General Motors' (GM) official racing teams since 1999 when they were the key responsibility in the development of the Chevrolet Corvette C5-R. Today, Pratt & Miller constructs, maintains, and runs the WeatherTech SportsCar Championship Corvette Racing team with the Chevrolet Corvette C8.R as well as the Pirelli World Challenge Team Cadillac ATS-Vs. The company also built the Pontiac GTO.R and Pontiac GXP.R, and later the Chevrolet Camaro GT/GS.R for various teams in the Rolex Sports Car Series. The company built and ran the Chevrolet Corvette C6.R in the American Le Mans Series (ALMS) as well.
Since their alliance with GM, Pratt & Miller have won numerous championships and famous racing events. Corvette Racing has won their class at the 24 Hours of Le Mans eight times, claimed the overall victory at the Rolex 24 at Daytona in 2001, and won seven straight American Le Mans Series championships. Team Cadillac won the 2005 Speed World Challenge in the team's debut season, while The Racer's Group, running Pratt & Miller-built Pontiac GTO.Rs, won the Rolex Sports Car Series championship in 2006. GM Racing's Katech-built LS7.R small-block engine was also named the 2006 Global Motorsport Engine of the Year. Katech built the C5-R and LS7.R engines that powered the C5-R and C6.R Corvettes in the GTS/GT1 classes of ALMS and the 24 Hours of Le Mans. After Le Mans 2009, Corvette Racing switched to the GT2 class and decided to bring the engine builds in-house. Corvette Racing won the 2012 and 2013 American Le Mans Series GT Team's and Manufacturer's Championships.
One of the company's first products was the Intrepid RM-1 GTP car, built in 1991.
