The 2025 Chevrolet Corvette ZR1 is America’s undisputed King of the Hill as it’s been unveiled with the most powerful V8 from the Land of the Free. With its mind-bending specs, it’s out of challenge the world’s best supercars—be it coupe or convertible.
Cutting to the chase, the Corvette ZR1 has a twin-turbo 5.5-liter flat-plane crank V8 engine dubbed the LT7. The LT7 engine produces 1,064 horsepower at 7,000 rpm and 1,123 Nm of torque at 6,000 rpm—the most powerful ever from a factory Corvette and the most powerful V8 ever produced in America from a carmaker.
Chevrolet estimates it will do the quarter mile in less than 10 seconds, while going over 346 km/h road permitting.
The engine itself shares the same architecture as the base Z06’s LT6. Dubbed the “Gemini V8” architecture, engineers in the LT6 engine program had a dual-pathed goal: create power, capability, and character from a normally-aspirated powerplant, but ready the system for an eventual boosted application. This is where the LT7 takes over. Changes include new head casting, a larger combustion chamber, optimized valvetrain timing and lift, CNC-machined intake and exhaust ports, and of course, dual mono-scroll 76 mm turbochargers integrated with the exhaust manifold.
The accompanying 8-speed dual clutch automatic has also been strengthened to handle all that extra load.
With all that power, Chevrolet made sure to give the Corvette ZR1 functional aero upgrades with a flow-through hood, carbon fiber side profile air ducts, and unique air ducts. Serving as a design statement, Chevrolet brings back the split rear window in the ZR1. This carbon fiber “spine” between the two rear windows provides increased heat extraction from the engine compartment, working in parallel with numerous other cooling elements throughout ZR1. The roof material has also been swapped out to carbon fiber for reduced mass and lower center of gravity.
For those who want to take things to the extreme, there’s the ZTK package that bundles an aggressive, high-downforce rear wing, front dive planes, and a tall hood Gurney lip—all constructed from woven carbon fiber. Underneath, underbody strakes replace the standard front underwing stall Gurney to increase front downforce.
Suspension-wise, the Corvette ZR1 comes with Magnetic Ride dampers and Michelin Pilot Sport 4S tires sized 20s in the front and 21s at the back. The ZTK stiffens the springs and swaps out the tires for Michelin Pilot Sport Cup 2 R tires.
Peeking out of the four corners is the Corvette’s new high-performance braking system with carbon ceramic rotors. Front rotors measure 15.7 inches (400mm) in diameter and rear rotors 15.4 inches (390mm) in diameter—the front rotors, notably, are the largest ever equipped on a Corvette.
The Chevrolet Corvette ZR1 will enter production in 2025 and will be built at General Motors’ Bowling Green Assembly Plant in Kentucky. It joins Corvette Stingray, Corvette Z06, and Corvette E-Ray to continue elevating the Corvette family.
