Chevrolet just gave one of its most beloved Corvette badges a jolt of electricity, and the result reads like a challenge to sports cars that cost twice as much. The 2027 Grand Sport X pairs a howling V-8 with an electrified front axle, and it does the whole thing for a price that makes European exotics look overpriced.
- 721 horsepower and 655 pound-feet of torque from a hybrid, all-wheel-drive setup
- A base coupe price of $112,195, less than half of the flagship ZR1X
- Zero to 60 mph in a claimed 2.4 seconds and a 10.4-second quarter mile
What the X Badge Actually Changes
The Grand Sport name has meant one thing to Corvette fans for decades. It’s the trim that balances speed and value better than anything else in the lineup. Adding an “X” turns that reputation up a few notches. This is the first Grand Sport built as a super-hybrid, and it borrows its electrified front axle almost wholesale from the 1,250-horsepower ZR1X, the record setter that hit 233 mph. Most of the internal part numbers are identical.
The layout is unusual and clever. Electric power drives the front wheels, while the gasoline V-8 sends its output to the rear. There’s no physical connection between the two axles, so software has to coordinate the handoff. When it works, and it does, the car feels like it’s cheating physics compared to purely gas-powered rivals.
The Engine Does the Talking
At the heart of the GSX sits a new LS6 V-8 displacing 409 cubic inches. Push the start button and it crackles awake before dropping into a low, menacing idle. Floor it and the cabin fills with the kind of sound that could score a Christopher Nolan film. On its own, that gas engine makes 520 pound-feet of torque, a high-water mark for any production V-8 without a turbo or supercharger.
The electric motor adds 186 horsepower and 145 pound-feet, filling every gap in the powerband with an unbroken push. Combined output lands at 721 horsepower, a 186-hp jump over a standard Grand Sport or 2027 Stingray. For context, that beats a McLaren Artura’s 690 horses, and the Artura starts around $260,000. There’s engineering nuance under the hood too. Forged cylinders can shut off to save fuel, and a 13:1 compression ratio helps the engine burn cleaner while cutting emissions by 28 percent versus its predecessor.
Numbers That Embarrass the Competition
Chevy claims a launch-controlled sprint to 60 mph in 2.4 seconds and a quarter mile in 10.4 seconds at 131 mph. Those figures came close to reality even on lumpy upstate New York backroads, where a 2.6-second run to 60 was possible. That’s 0.1 seconds quicker than the outgoing E-Ray and 0.2 seconds quicker than the flat-crank Z06.
The E-Ray it replaces was a smooth grand tourer, fast but relaxed. The GSX takes a harder line. GM engineers built it as a track weapon with sharper power, braking, and agility, and they nicknamed it the “baby ZR1X.” A tiny 1.9-kilowatt-hour battery lives in the chassis spine between the seats. It isn’t there for efficiency or electric-only driving. Instead it soaks up regenerative energy like a sponge and fires it back out in quick bursts.
Where the Value Really Lands
Pricing is the headline that keeps giving. The GSX coupe starts at $112,195, while the ZR1X asks $227,395. A non-hybrid, 535-horsepower Grand Sport comes in at $88,495 for buyers who don’t need the extra muscle. The LS6 also becomes standard in the 2027 Stingray, which drops to $73,495 and still manages a 25-mpg highway rating while flirting with 200 mph.
A few options are worth checking. The $1,995 performance exhaust sharpens the sound through four center-mounted outlets, and a $2,995 front-end lift keeps the low splitter from scraping steep driveways. Fuel economy isn’t part of the pitch. The GSX topped out around 22 mpg and dipped to 11 during hard runs, which feels beside the point.
A Reason to Get Excited
The Grand Sport X shows that hybrids don’t have to mean penny-pinching commuter cars. With hybrids outselling EVs nearly three to one in the U.S. this year, Chevrolet is proving that electrified power can make a sports car quicker, louder, and more thrilling rather than tamer. If you want supercar acceleration without a supercar loan, this Corvette makes a strong argument. Take one for a test drive, and the badge will do the rest of the convincing.
