The new mid-engined Corvette will debut at the 2020 24 Hours of Daytona.
Chevrolet begins a new chapter in its historic legacy in the world of competition with the introduction of the new Corvette C8.R, the brand's first mid-engined race car to compete in the GTLM class of IMSA. This model, which replaces the C5.R which hit the track in 1999, will debut at the 2020 edition of the 24 Hours of Daytona.
The C8.R is based on the 2020 Corvette Stingray. "It was important for us to develop the new race car in parallel with the production car, so that each product could properly take advantage of the new architecture." explained Ed piatek, chief engineer of the Corvette. "The benefits of this mid-engined supercar, including its incredible balance and the feeling of being connected to the road, will be obvious on the streets and on the track." said.
Since certain features of the 2020 Corvette Stingray are not necessary in a racing environment, engineering and design teams found innovative ways to profit from every part of the vehicle.
For example, in the C8.R it was placed a single radiator centrally mounted in the area used as the front storage compartment on the production Corvette. While the ultra-bright racing headlights They were placed in the race car where the radiators are located in the production car.
In compliance with the IMSA rules, The C8.R will feature a naturally aspirated 8L V5.5 engine producing 500 horsepower. In addition, it is equipped with a new compact six-speed Xtrac gearbox with sequential gears to provide space at the rear of the C8.R to fit a special race car diffuser.
"We've been looking to compete with a production car-based mid-engine Corvette for a long time," explained Jim campbell, Vice President of Performance and Motorsports for Chevrolet in the United States.
“The debut of the C8.R is the result of an immense collaboration between GM's engineering, propulsion and design team and the Corvette Racing team. As Corvette Racing enters its third decade of competition, we are excited to begin the next chapter. ” He added.
Improving aerodynamics, increasing stiffness, and decreasing the weight of the previous generation car were all main focuses of the C8.R's development.
The use of computerized analysis It enabled the design of the race car to be started well in advance of the availability of any production Corvette component. A state-of-the-art Chevrolet simulator was used to evaluate numerous chassis and aerodynamic design concepts.
Engineering and design teams produced thousands of 3D parts for testing chassis and wind tunnel. The use of these development tools resulted in a race car with improved aerodynamics, dynamics, and weight distribution.
The C8.R uses a production 2020 Stingray chassis built at the Bowling Green Assembly Plant. It was later modified to meet the requirements of the series and is therefore stiffer and lighter than its predecessor.
With a lower center of gravity and a more even weight distribution on the wheels, Corvette Racing worked closely with Michelin to optimize tire material and construction to better meet the unique traction needs of a mid-engined race car.
