As the power behind the 2019 Corvette ZR1, the new supercharged 6.2L LT5 represents the pinnacle of Chevrolet's performance: It's the most powerful engine ever offered in a Chevy production vehicle.
The Zora will be the most powerful C8 Corvette, producing 1000 horsepower and 975 lb-ft of torque.
After a 14-year absence, the ZR-1 returned for 2009 as the fastest Corvette of all time, with a supercharged 6.2-liter V8 making a whopping 638-horsepower!
The Chevrolet Corvette C8 ZR1 is expected to arrive for the 2023 model year with a twin-turbo V8 engine, more aggressive looks, and more all-around capability than the C8 Z06, whether on the track or on the road. It is expected to be followed by the C8 Zora.

That's about 4.5 psi more than the LT4 engine, but achieved with a slower, 15,860-rpm maximum rotor speed, which helps keep down the pressurized air charge's temperature.
As heart of the Corvette ZR1, the supercharged LT5 6.2L SC is the most powerful engine ever offered in a regular production Chevrolet. It features a more-efficient, more-compact 2.6L Eaton R2650 TVS supercharger. That's enough to generate more than 9 pounds of boost and help produce 755 horsepower and 715 lb. -ft.
The ChemistryWe didn't get to drive a ZR1 fitted with its $1725 eight-speed automatic transmission on the road, but clutch takeup on the standard seven-speed manual is progressive and impressively light in effort.
