MID-ENGINE CORVETTE C8.R FOR NEXT RACING SEASON
A New Chapter of Corvette Racing Begins
Oshawa, Ontario — Chevrolet begins a new chapter in its storied racing legacy with the introduction of the new mid-engine Corvette race car, known as the C8.R. The C8.R will be Chevrolet’s first mid-engine race car to compete in IMSA’s GTLM class and the first clean sheet race car design since the C5.R debuted in 1999. It will make its racing debut at Rolex 24 at Daytona on Jan. 25, 2020.
The 2020 Corvette C8.R is based on the strong foundation of the 2020 Corvette Stingray. There is a deeper level of technology transfer between the race car and production Corvette than ever before, which helps contribute to many of its advancements. As a result, the 2020 Corvette C8.R shares the highest percentage of parts between the production and race car than any previous generation.
Engineered for the Racing Environment
Since certain features of the 2020 Corvette Stingray aren’t necessary in a racing environment, the engineering and design teams found innovative ways to get benefits out of every part of the vehicle. For example, on the C8.R, a single centrally-mounted radiator was placed in the area used as the front storage compartment on the production Corvette. Ultra-bright racing headlights were packaged on the race car where the radiators are located on the production car.
In compliance with IMSA engine displacement rules, the 2020 Corvette C8 Racing will feature a 5.5L naturally-aspirated V8 engine, producing 500 hp and 480 ft.-lb. of torque.
A new compact Xtrac six-speed sequential gearbox was developed in order to provide room at the rear of the C8.R to package a race car specific diffuser.
Designed to Improve Aero, Weight and Stiffness
Improving aerodynamics, increasing stiffness and decreasing weight from the previous generation car were all primary focuses of the C8.R development.
The use of computer analytics made it possible to start the design of the race car well in advance of any production Corvette components being available. Chevrolet’s state of the art Driver in the Loop Simulator was heavily utilized to evaluate numerous chassis and aero design concepts. The engineering and design teams produced thousands of 3D-printed rapid prototype parts for chassis and wind tunnel testing. The use of these development tools resulted in a race car with improved aerodynamics, vehicle dynamics and weight distribution.
The C8.R utilizes a production 2020 Stingray chassis structure produced in the Bowling Green Assembly plant. The chassis is then modified to meet race series requirements. The new C8.R chassis structure is significantly stiffer and lighter than its predecessor.
With a lower centre of gravity and more even weight distribution on the wheels, Corvette Racing worked closely with Michelin to optimize the tire compound and construction to best support the unique traction needs of a mid-engine race car. The C8.R will ride on 18 inch MICHELIN® Pilot® Sport GT competition tires.
Sporting Both Yellow and Silver
While yellow continues to be a mainstay of Corvette Racing, it is now joined by a new look for the 2020 season on the 2020 Corvette C8.R.
The No. 4 race car features a new silver livery, inspired by the colour of iconic Corvette concepts such as the 1959 Corvette Stingray Racer that pushed the envelope both in design and on-track performance. This car also features yellow accents.
It will be joined by the No. 3 race car in a yellow colour scheme with silver accents that continues the lineage of the successful GTLM racing Corvettes.
Debuts at Road Atlanta, To Race at Daytona
Prior to its 2020 debut at Rolex 24 at Daytona, the 2020 Corvette C8.R will stretch its legs on the Road Atlanta Michelin Raceway by performing a ceremonial lap on the track prior to the 22nd annual Petit Le Mans race this weekend. The only Canadian stop on the tour will take place at Canadian Tire Motorsport Park in Bowmanville, Ontario in summer 2020
