Development

Having already established the C5-R as a winning car, the development of the C6.R was more of an evolution of a design rather than an all new car which required long periods of testing and design. Pratt & Miller's process was aided by the fact that, unlike the C5-R which debuted several years after the C5 generation Corvette was on the streets, the C6.R and C6 generation Corvettes would be developed at the same time. This meant that design elements which would help the race car could be adapted to the road car, allowing the C6.R to use more exotic design features but still meet homologation requirements. In turn, this meant racing elements could be adapted to the Corvette Z06 performance car, which the C6.R shares it exterior styling with.
Much of the framework of the road legal C6 was retained on the C6.R, leading to increased use of weight-saving aluminium

. The road car would also replace the C5's pop-up headlamps with permanent designs integrated into the bodywork. This meant that the racing car would have better air flow over the front of the car, doing away with their replacements for the pop-up headlamps which stuck out of the bodywork. The large grill opening on the car would also serve to eliminate the variety of openings on the C5-R to feed not only the brake cooling ducts, but also help with downforce by exiting back out the top of the bonnet.

Underneath, the C6.R retained much of the mechanical elements from the C5-R. The same Katech-built 7.0 litre V8 was used, but more closely based on the LS7

 from the Z06. This engine, known as the LS7.R, would go on to earn the Global Motorsports Engine of the Year award in 2006 for its performance and endurance capabilities. Like the C5-R, the C6.R lacked a rear window due to structural framework and fuel tanks taking up the space behind the cockpit. However, an innovation on the C6.R was the addition of a small video camera into the rear bumper, and a monitor placed on the roof of the cockpit. This allowed the drivers a better view behind them, instead of having to rely on their side mirrors.

Another innovation was the use of an air conditioning

 system in the car in order to help drivers better endure high cockpit temperatures. This required the addition of a large suction fan to the rear of the car, as well as intakes integrated into the side mirrors. One innovation which the C6.R debuted in 2007 was the use of variable displacement

 led the team to remove it from the cars until it could be further evaluated.

As of the end of the 2007 season, six C6.Rs had been built by Pratt & Miller. A seventh car, used for development work, was actually built on a C5-R chassis but adapted to carry C6.R bodywork. This car has never raced and is used merely as a show car, making its public debut alongside the C6 Corvette at the 2005 North American International Auto Show

Following the retirement of the C5-R at the end of 2004, the factory Corvette Racing squad started 2005 with two brand new C6.Rs. Unlike the previous car, which ran only select events until it could be proven quick and reliable, the C6.Rs would compete in the full American Le Mans Series

Prodrive returned to Europe after Sebring, and Corvette Racing was able to earn wins in each of the succeeding races that season.

, where the team were able to outlast the quicker DBR9s to earn a 1-2 victory in the GT1 class and finish fifth and sixth overall.

In 2006, Prodrive chose to concentrate on the American Le Mans Series, giving Corvette Racing a battle throughout the season. Corvette Racing avenged their loss at Sebring, but Aston Martin managed their own victories later in the season. The two teams were close in the points championship throughout the season, before Corvette Racing managed to earn a three-point margin in the last race and won their second straight championship. At Le Mans, the Aston Martins once again faltered with reliability problems after leading the event, allowing a Corvette C6.R to finish the race fourth overall and win the GT1 class.

Following the 2006 season, Prodrive returned to Europe to concentrate on improving the DBR9 for Le Mans. This meant that Corvette Racing was left without a major opponent in the American Le Mans Series, and in fact were the only competitors in the GT1 class for nine out of twelve races that year, and easily allowing Corvette Racing to earn their third championship. At Le Mans, the Corvettes were not able to repeat their previous success as Aston Martin was finally able to reliably maintain their pace over 24 hours and earn their first class victory, leaving Corvette Racing with second.

Privateer teams

Like the C5-R, C6.Rs which had been used by the factory team eventually ended up in the hands of privateers once they were replaced by newer chassis. Unlike before, these Corvettes were sold less than a year after they had debuted, rather than the four years it took for a C5-R to be sold to another team. Corvette Motorsport, based in Belgium, currently handles the unity of teams and media promotion for the privateers currently competing in Europe.

GLPK-Carsport

GLPK-Carsport was formed by Belgian entrepreneur Paul Kumpen and Toine Hezemans following a merger of PK Carsport and Carsport Holland. After running the C5-R successfully in 2005, Toine Hezemans decided to buy one of the two C6.Rs used by Corvette Racing during the 2005 season.

Corvette C6.R GT2

On September 9, 2008 Corvette Racing GM Road Racing Group manager Steve Wesoloski and Corvette Racing program manager Doug Fehan announced that for the 2009 ALMS season they would be running the C6.R in the GT1 class for only the first half of the season. After the 24 hours of Le Mans, Corvette Racing will be running a newly designed C6.R in the GT2 class in preparation for the 2010 season's newly designed GT class regulations.

The car uses a newly designed 6.0L V8 making 470 bhp, which is based on the 7.0L LS7.R from the GT1 car (which produced 590 bhp). As part of the GT regulations for 2010, the engine would be downsized to 5.5L to comply with the new engine displacement limits. The new GT2 car takes body styling cues from the then new Corvette ZR1 street car. The car sports a new aluminum frame (the GT1 car had a steel frame), smaller front splitter and rear wing, and steel brakes (the GT1 used carbon ceramic brakes), bringing it closer to the build of the Z06 road car. Due to its 5.5L motor displacement, the car was penalized with extra weight and waivers, much to the advantage of the competing Ferrari F430 GTC, whose powerplant generated the same 500bhp but from a 4.0L V8.

The new GT2 car began its campaign in the GT2 class starting with the 2009 Mid Ohio
