Unmatched Power and Performance
At the heart of the 2025 Chevrolet Corvette ZR1 is the LT7 engine, a 5.5L twin-turbocharged DOHC flat-plane crank V8. This powerhouse delivers an astonishing 1,064 horsepower at 7,000 rpm and 828 lb-ft (1123 Nm) of torque at 6,000 rpm, making it the most powerful V8 ever produced in America by an auto manufacturer. According to SAE guidelines, the Corvette ZR1 can achieve a GM-estimated top speed of over 215 mph (346 km/h) on the racetrack and can complete a quarter-mile in under 10 seconds.

Advanced Engineering and Design
The ZR1’s performance is not just about raw power. Its purposeful carbon fiber aero package creates over 1,200 pounds (544 kg) of downforce at top speed, ensuring it stays planted on the track. The iconic split rear window, a nod to Corvette’s rich history, returns to enhance both style and function.
“The team that revolutionized Corvette with a mid-engine architecture took on another challenge: take ZR1 to the next level,” said Scott Bell, vice president of Chevrolet.“Corvette ZR1 is about pushing the envelope with raw power and cutting-edge innovation. From Stingray, to Z06, E-Ray, and now ZR1, the Corvette family continues to elevate with each new iteration — and challenge the best in the world.”
The LT7 Engine: A Marvel of Modern Engineering
The LT7 engine is a testament to Chevrolet’s engineering prowess. Building on the architecture of the Z06’s LT6, the LT7 is the first factory Corvette engine to feature twin turbochargers. Dubbed the “Small Block Gemini” architecture, the LT6 program laid the foundation for the LT7, focusing on creating massive power, capability, and character from both naturally aspirated and turbocharged flat-plane crankshaft engines.

Unique features of the 5.5L LT7 twin-turbo V8 engine include:
- Head castings with unique ports and a larger combustion chamber
- Valve train timing and lift profile optimized for forced induction
- A completely new intake system tuned for twin turbochargers
- CNC machined combustion chamber, exhaust, and intake ports specific to the LT7
- Dual, ported shroud, ball bearing, mono-scroll (76 mm) turbochargers integrated with the exhaust manifold for quick response with electronic wastegates
- Intelligent anti-lag engine calibration techniques that adapt and react to driving style
Building on Advanced Engineering
The LT7 engine also builds upon this engine architecture with:
- Added block and head machining to support turbo cooling and oiling
- Counterweight changes to account for a unique piston, and unique connecting rod for the crank train
- A secondary port fuel injection system added to deliver the needed additional fuel to support the engine’s massive output
Transmission and Chassis Enhancements
To handle the LT7’s dramatic power increase, the Corvette ZR1’s eight-speed dual-clutch transmission has been upgraded with stronger inner and outer input shafts, increased gear capacity, and enhanced oil management to support the vehicle’s higher longitudinal and lateral capability.
The ZR1’s chassis is designed for both comfort and performance. The standard chassis features a sleeker body with lower drag, a small spoiler with customer-adjustable short and tall wickers, and a standard carbon-fiber front splitter. Michelin Pilot Sport 4S tires wrap 20-inch front and 21-inch rear wheels. For those seeking even more track capability, the optional ZTK performance package adds an aggressive high-downforce rear wing, front dive planes, a tall hood Gurney lip, and Michelin Pilot Sport Cup 2 R tires.
Cutting-Edge Aerodynamics
The Corvette ZR1’s aerodynamics are designed to provide the most downforce ever from a Corvette. The flow-through hood allows air to enter through the front grille, pass through the intercooler heat exchanger, and exit through the hood, increasing front downforce and cooling charged air temperatures. Carbon fiber side profile air ducts and unique fresh air intake ducts further enhance cooling and performance.
Advanced Braking System
To control the ZR1’s high performance, Chevrolet has equipped it with a revolutionary brake system. The brake package uses carbon ceramic rotor technology, resulting in increased durability and reduced brake component temperatures. The front rotors measure 15.7 inches (400mm) in diameter, and the rear rotors measure 15.4 inches (390mm) in diameter, making them the largest ever equipped on a Corvette. The ZR1 can go from 80-200 mph and back to 80 mph (129 – 321 – 129 kph) in just 24.5 seconds, 22% quicker than the C7 Corvette ZR1, and 53% quicker than the C6 Corvette ZR1.
Iconic Design with Modern Touches
The new Corvette ZR1 brings back the beloved split rear window, last seen on the C2-generation Corvette. This carbon fiber “spine” between the two rear windows not only serves as a design statement but also helps extract heat from the engine compartment. The ZR1’s design focuses on both function and aesthetics, with a carbon fiber roof to reduce mass and lower the center of gravity, unique aluminum wheel designs, and an exclusive carbon-fiber wheel option.
Luxurious Interior with Attention to Detail

Inside, the Corvette ZR1 offers a cockpit that emphasizes attention to detail. Unique ZR1 badging is found on the interior plaque, sill plates, and steering wheel. A new finishing stitch pattern for the doors is available on the 3LZ trim, and a boost gauge is present, denoting the first factory turbocharged Corvette in the nameplate’s history. New interior color options, such as Habanero and Blue Stitch, add to the customization choices for customers.
Production and Availability
The 2025 Chevrolet Corvette ZR1 will enter production in 2025 at General Motors’ Bowling Green Assembly Plant in Kentucky. It will join the Corvette Stingray, Corvette Z06, and Corvette E-Ray in Chevrolet’s lineup of performance cars. Further details on price and availability will be shared closer to production.
Final Thoughts
The 2025 Chevrolet Corvette ZR1 sets a new benchmark for American supercars. With its unprecedented power, advanced engineering, and iconic design, it offers a driving experience like no other. Whether on the track or the open road, the ZR1 is poised to capture the hearts of car enthusiasts around the world, solidifying its place as the fastest, most powerful Corvette ever produced.
