The 2025 Chevrolet Corvette ZR1 marks a new benchmark in American supercar engineering, combining advanced aerodynamics, powertrain innovation, and motorsport-derived performance.
At its core is the LT7 engine, a 5.5-liter twin-turbocharged V8 with a flat-plane crankshaft. This engine produces 1,064 HPr at 7,000 rpm and 825 pound-feet of torque at 6,000 rpm, making it the most powerful V8 engine ever by GM.
The LT7 is a significant evolution of the naturally aspirated LT6 found in the Corvette Z06. Key changes include forged aluminum pistons, strengthened connecting rods, and twin 76 mm ball-bearing turbochargers integrated into the exhaust manifolds. The engine also features an anti-lag system that maintains boost pressure during throttle lift-off, ensuring immediate power delivery when re-engaged.
Power is delivered to the rear wheels via a dual-clutch 8-speed transmission that has been reinforced to handle the increased torque. Chevrolet estimates 0 to 60 mph in 2.3 seconds, with a top speed exceeding 215 mph. In private testing, the 2025 Corvette ZR1 has achieved verified runs over 230 mph, including a peak of 233.
Standard models of the 2025 Corvette ZR1 feature a front splitter, underbody strakes, and an active rear spoiler. With the available ZTK package, the ZR1 gains a large fixed rear wing, dive planes, and additional carbon-fiber components. Combined, these upgrades provide over 1,200 pounds of downforce.
Chassis tuning includes Magnetic Ride Control 4.0 and a track-optimized suspension geometry. The ZR1 is equipped with Michelin tires—20 inches at the front and 21 inches at the rear. Braking is handled by carbon-ceramic rotors, measuring 15.7 inches in front and 15.4 inches in the rear, with electronic brake boost providing consistent stopping power.
Cooling performance has been enhanced through several functional design elements. A center-mounted intercooler evacuates heat through a vented hood, while additional ducts in the front fascia and rear quarter panels direct airflow to critical systems. Roof and rear window have been optimized for thermal management.
