Chevrolet Unleashes Its Most Powerful Corvette to Date: The 2025 ZR1

Chevrolet has unveiled the 2025 Corvette ZR1, boasting the most powerful V8 engine ever produced by an American automaker. The ZR1 is available in both coupe and convertible variants, combining raw power with iconic design.

At the heart of the ZR1 is the 5.5L twin-turbocharged DOHC flat-plane crank V8 engine, known as the LT7. This engine generates 1,064 horsepower at 7,000 rpm and 828 lb-ft of torque at 6,000 rpm, making it the most potent factory-produced Corvette engine to date. Chevrolet estimates the ZR1’s top speed to exceed 215 mph, with a quarter-mile time under 10 seconds.

The ZR1’s aerodynamic design features a carbon fiber aero package that produces over 1,200 pounds of downforce at top speed. A notable design revival includes the split rear window, paying homage to classic Corvette styling.

Scott Bell, the VP of Chevrolet shared “The team that revolutionized Corvette with a mid-engine architecture took on another challenge: take ZR1 to the next level,” adding “Corvette ZR1 is about pushing the envelope with raw power and cutting-edge innovation.”

The LT7 engine builds upon the architecture of the Z06’s LT6, incorporating twin turbochargers for the first time in a factory Corvette. Engineers optimized every system for a boosted application, resulting in unique head castings, valve train timing and a new intake system tailored for twin turbos. Enhanced performance extends to the ZR1’s transmission, featuring upgraded inner and outer input shafts, increased gear capacity and refined oil management to support the engine’s massive output.

Purposeful aerodynamics and a new brake system with carbon ceramic rotors ensure the ZR1’s handling matches its power. The optional ZTK performance package adds an aggressive high-downforce rear wing, front dive planes and Michelin Pilot Sport Cup 2 R tires for track-ready performance.

Production of the 2025 Corvette ZR1 will commence at General Motors’ Bowling Green Assembly Plant in Kentucky, joining the Corvette Stingray, Z06 and E-Ray models. Further details on pricing and availability have yet to be shared at the time of writing but are expected to be announced as closer to production.
