There’s a long-running argument among Corvette people (and there are many of them) that the Grand Sport — a trim level that sits above base ‘Vettes, and right below the track-oriented Z06 — is the sweet spot of the lineup.
Earlier this year, Chevy announced the Grand Sport would return to the Corvette lineup, and that’s another good piece of news for General Motors’ (GM) halo car that’s doing well at the moment, with Corvette sales up about 24% in Q2.
The Corvette is selling well, and it’s been pushing the performance envelope while its buyers keep getting younger
And now here comes the Grand Sport X, which carries a lot of the racing hardware and the good track stuff of sportier trims, but it’s more livable. For 2027, Chevrolet made it a very different animal
Under the hood is a beast, electrified
Every 2027 Grand Sport is powered by an all-new 6.7-liter naturally aspirated V8 making 535 horsepower and 520 lb-ft of torque. It’s an absolutely insane powerplant, a totally new V8 for GM, and it becomes Corvette’s standard engine across the Stingray and Grand Sport lineup.
It’s also the start of GM’s next generation of V8s, with the architecture set to trickle into other Chevrolets, including trucks, down the road
But the Grand Sport X takes that V8 and steps it up a notch, with the hybrid all-wheel-drive setup borrowed from the record-setting Corvette ZR1X.
There’s an electric motor and a compact battery driving the front axle, with an additional 186 horsepower and 145 lb-ft up front, and it recharges and discharges quickly. So you get V8 power at the rear wheels, two motors adding grip and maneuverability at the front, and a little electric propulsion in certain situations. Combined output is a monstrous 721 horsepower.
The model is the only hybrid GM currently sells, though the company has said it wants to add more to its lineup. The Grand Sport X replaces the E-Ray, and if you want an all-wheel-drive Corvette, it’s the only entry point now. The ZR1X above it is a whole different beast; we’re talking upward of $200,000 and 1,000 horsepower.
But the Grand Sport X is no slouch. Chevy revealed this week it will hit 60 mph in 2.4 seconds, with a 10.4-second quarter-mile at a brisk 131 mph and an 186-mph top speed
The way it looks, inside and out
Inside the cabin is the new-generation Corvette cockpit, revealed a year ago. Chevy finally ditched the strip of buttons down the center for a more traditional dual-cockpit, dual-screen layout, with the drive mode selector in the middle for Sport, Tour, Track, and Corvette’s signature dialed-in Z mode. It’s leather everywhere with a suede-like Alcantara headliner. It’s a genuinely nice place to be
