Corvette Racing then rolled the race car out before the start of Petit Le Mans, with American driver Tommy Milner turning a couple of demo laps in the car for fans in attendance.
Now Chevrolet has shown the Corvette C8.R once again—this time at the 2019 SEMA Show in Las Vegas. While the automaker refrained from sharing any more information on the car, this appearance gave us another chance to see the race car up close. The dark-tinted windshield and side windows still remain on the car, shielding prying eyes from seeing into the team’s radically different creation. The tinted windows were also on the car at the Corvette Convertible debut and when it made its appearance at Road Atlanta.
As we reported previously, the Corvette C8.R is powered by a new 32 valve, dual-overhead-cam 5.5-liter V8 engine with a flat-plane crankshaft. The naturally aspirated V8 engine is rated at 500 horsepower and 480 pound-feet of torque—though IMSA’s regulations for the production-based GTLM class put a limit on the amount of power the engine can produce. Power is sent to the rear wheels through a new six-speed sequential transmission supplied by Xtrac. The gearbox was developed specifically for the C8.R, as it has very little room in the rear due to its massive rear diffuser.
Chevrolet has confirmed the new DOHC flat-plane-crank V8 is a production-based engine. This means it will find its way into a road-going Corvette C8 model—likely the new Corvette Z06. A twin-turbocharged version of this new 5.5-liter engine is expected to power the C8 Corvette ZR1 as well.
The Corvette C8.R will make its competition debut at the 2020 24 Hours of Daytona in late January. Most race fans will have to wait until then to see the car in person, but those lucky enough to attend SEMA this year can see the car on display at the aftermarket event.
