Last month, Chevrolet and Pratt Miller Motorsports officials announced the formation of Corvette Racing by Pratt Miller Motorsports (PMM) to lead competition and development with the Chevrolet Corvette Z06 GT3.R. Starting off strong at the 2024 Rolex 24 At Daytona, the new program will campaign a pair of the new-for-2024, GT3-spec Corvettes for a full season in the GT Daytona (GTD) PRO category of the IMSA WeatherTech SportsCar Championship.

This collaboration comes as a perfect fit between Chevrolet and PMM, with the current full-factory Corvette Racing program in its 25th season with 125 race victories. Most recently at the 24 Hours of Le Mans for the team’s ninth class win at the famed French classic. Plus, Corvette Racing has programs in both IMSA and the FIA World Endurance Championship with the Corvette C8.R, which is now in its final season of competition, for two seasons in a row. 

“Chevrolet and Pratt Miller have collaborated for more than 25 years on the Corvette Racing program, and we are thrilled that we are able to continue together into the GT3 era,” said Christie Bagne, program manager, Corvette Z06 GT3.R.

The planning between each team began two years ago for the Corvette GT3 era. Pratt Miller — located in New Hudson, Michigan — is the constructor of the Z06 GT3.R, with engineers who have worked hand-in-hand with Chevrolet Motorsports engineers on development, build and testing of the vehicle. Miller has dedicated to chassis builds and engineering on the Z06 GT3.R, while the GM Propulsion Performance and Racing Center in Pontiac, Michigan, has focused on the development and refinement of the 5.5L, flat-plane crankshaft DOHC LT6 V-8 engine that will power the racecar.

Corvette Racing and Pratt Miller have accumulated nearly 9,000 kilometers (5,500 miles) with the Corvette Z06 GT3.R since September of last year. The car currently is undergoing its final homologation testing in Europe with additional testing planned for the summer and fall to fine-tune the Z06 GT3.R to multiple brands of tires for use across an array of championships around the world.

“This is an exciting time for everyone at Pratt Miller,” said Brandon Widmer, Pratt Miller Vice President, Motorsports. “We’ve experienced a lot of successes, race wins and championships with Chevrolet through the Corvette Racing program. Now we move into the GT3 era. Everyone is pleased with the progress of our testing and development programs, and new car builds are under way.”
