2020 Chevrolet Corvette C8

Chevrolet Corvette ZR1

Chevrolet has unleashed the unthinkable in the Corvette ZR1. The King of the Hill returns with the most powerful V8 ever produced in America from an auto manufacturer, mind-bending specs and iconic design to challenge the world's best supercars in both coupe and convertible variants.

- Corvette ZR1 features a 5.5L, twin-turbocharged DOHC flat-plane crank V8 engine dubbed the LT7.
- The LT7 engine produces 1,064 horsepower at 7,000 rpm and 828 lb-ft of torque at 6,000 rpm, per SAE guidelines - the most power ever from a factory Corvette and the most powerful V8 ever produced in America from an auto manufacturer.
- Corvette ZR1 boasts a GM-estimated top speed of over 215 mph on the racetrack and will dispatch the quarter mile with a GM-estimated sub-10-second time.
- Purposeful carbon fiber aero package creates over 1,200 pounds of downforce at top speed.
- ZR1 revives one of the most iconic styles in Corvette history: the split rear window.

"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, 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."

Pushing the boundaries of Engine Development

ZR1's 5.5L LT7 twin-turbocharged DOHC V8 engine starts with the same architecture as Z06's LT6, the most powerful naturally aspirated production V8 engine ever, and takes it to the next level with twin turbochargers - the first time ever for a factory Corvette.

This is the new Corvette ZR1: a 1,064bhp twin-turbo speed machine

Chevy unleashes the most powerful factory ‘Vette ever built. Be afraid

“Take ZR1 to the next level,” was Chevy’s mission statement. It appears its engineers have taken it to another galaxy, because this isn’t just the most powerful Corvette ever built, it’s a car with the most powerful American production V8 in history.

Sorry Dodge Demon, your 1,025bhp crown has been blown away in a haze of twin-turbo fury by this: the 1,064bhp Corvette ZR1. Though it takes the same ‘Small Block Gemini’ engine architecture as the Z06’s LT6, it’s not just that plus turbo.

Now called ‘LT7’, the 5.5-litre V8 with a flat-plane crank features new head castings, unique ports, a bigger combustion chamber for bigger bangs, optimised valve timing and a new intake system, and of course, a pair of 76mm mono-scroll blowers built into the exhaust.

This, says Chevy, reduces the distance the angry air must travel, so it very quickly gets into the chambers and reacts… angrily. Naturally, everything’s been strengthened across the board in order to deal with “the dramatic increase in power”. And hoo boy, does it have power.

 
1,064-Horsepower 2025 Chevrolet Corvette ZR1 Is A Shock To The Supercar System

The most powerful Corvette ever is so much more car than we expected.

I don’t know what I was expecting to hear — I was pretty bleary from a monster EV road trip. But when the Chevrolet engineer said “1,064 horsepower,” the words “holy ****” escaped my mouth. I really try not to give that kind of feedback, but the 2025 Chevrolet Corvette ZR1 warrants it.

A four-figure horsepower number isn’t the exclusive province of sketchy tuner cars anymore; there are a handful of warrantied engines and electric motor arrays making over a thousand horsepower, but mostly they do it in cars that weigh as much as a full-size pickup or more. The new ZR1 weighs 3670 pounds in coupe form and 3758 pounds in convertible form, which is within around 100 pounds of a Porsche 911 Turbo S. This mega-powerful powerplant is going to live in a relatively lightweight car, built by some of the best chassis engineers on the planet.

The ZR1's power figure is the headline, but things get wilder as you dig through the rest of the specs. The twin-turbocharged 5.5-liter LT7 V8 engine will also deliver 828 pound-feet of torque, and it’s mated to a strengthened 8-speed dual-clutch automatic sending power to the rear wheels. That means it has 394 hp and 368 lb-ft more than the naturally aspirated Z06, and 409 hp and 233 lb-ft more than the E-Ray hybrid. It should run the quarter-mile in under 10 seconds on its way to a 215-mph top speed. Downforce at that top speed is at 1200 pounds.
