2023 Chevrolet Corvette ZR1 Coming With Twin-Turbo V8 Making 850 HP: Report

Development of the Chevrolet Corvette ZR1 is now underway, and Muscle Cars & Trucks claims to have insider info about the model that allegedly comes from “bulletproof sources.”

These insiders reiterate the claim that the ZR1 uses a twin-turbocharged version of the 5.5-liter V8 from the Z06. The addition of forced induction allegedly brings the output to about 850 horsepower (634 kilowatts), versus 670 hp for the naturally aspirated variant in the Z06. The only gearbox choice is reportedly the Tremec-sourced eight-speed dual-clutch gearbox from other C8 Corvettes.

The ZR1 has a more aggressive body to match its additional power. There is new styling for the front and rear fascia, this report claims. Like the Z06, the exhausts exit out of the center of the back bodywork. The wheels are allegedly a unique design for this model. Michelin Pilot Sport 4S would be the stock tire choice, but a performance package reportedly upgrades them to Pilot Sport Cup 2R rubber.

Muscle Cars & Trucks claims the ZR1 arrives for the 2025 or ’26 model year. This is later than previous rumors that put the vehicle’s debut in 2023, suggesting it would be a 2024 model year product.
