Pratt Miller Engineering, also known as Pratt & Miller, is an American company involved in the automotive and arms industries. It was founded by Gary Pratt and Jim Miller in 1989. A defense division was added in 2013 and the company was acquired by Oshkosh Corporation in 2020.[1] The company is headquartered in the unincorporated community of New Hudson, in Lyon Township, Oakland County, Michigan. They are best known as service providers for many of General Motors' motorsports programs,[2] including the operation of the Corvette Racing team.[1]

Racing history

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 nine 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 seven Pirelli World Challenge championships,[3] while The Racer's Group, running Pratt Miller-built Pontiac GTO.Rs,[4] 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.

Pratt Miller developed a road-going tuned version of the Chevrolet Corvette C6 named C6RS. The C6RS was powered by a 500 cubic inch LS-based engine developed and built by Katech Inc.

One of the company's first products was the Intrepid RM-1 GTP car, built in 1991.
