According to GM Authority, Chevy has started actively testing the new C8 ZR1!

The eighth-generation Chevy Corvette C8 lineup continues to expand, with the “base model” C8 Stingray and track-ready C8 Z06 set to be joined by the upcoming Chevy Corvette C8 ZR1. Now, GM Authority has learned from sources familiar with the matter that team Corvette is actively developing the Corvette C8 ZR1.

For those readers who may be unaware, the Corvette C8 ZR1 is slated to arrive as the “next level” of go-faster machinery under the eighth-generation Vette umbrella, slotting in above the Z06 as an ultra-high performer for both the road and the track. The engine, drivetrain, chassis, and exterior styling are all expected to reflect this designation, differentiating the Corvette C8 ZR1 from the rest of the C8 lineup.

Per GM Authority sources, the Corvette team is now running the Corvette C8 ZR1 in an integrated prototype form, conducting vehicle tests both within GM’s facilities, as well as out in the real world.

One of the most important updates will be for the engine, with the Corvette C8 ZR1 utilizing a twin-turbocharged variant of the 5.5L V8 LT6 engine currently equipped by the Corvette C8 Z06. Known as the LT7, this boosted powerplant is expected to feature a DOHC configuration and 32 valves, with output around the 800-horsepower mark and a substantial boost in torque to around 850 pound-feet. The twin-turbo 5.5L V8 LT7 will also feature a lower redline and flatter power curve as compared to the naturally aspirated 5.5L V8 LT6 gasoline engine in the C8 Z06.
