- 2027 Corvette Grand Sport revives a historic name with a new 6.7L V8.
- New Grand Sport X adds eAWD and 721 hp using a front electric motor.
- Both introduce GM’s next-gen LS6 small-block, now standard in Stingray.
The long-awaited Corvette Grand Sport is finally here. For the 2027 model year, it returns as what many will see as the sweet spot in the lineup. At the same time, it adds a Grand Sport X trim and an all-new 6.7-liter V8 that will soon power the entire Corvette lineup.
Revealed at Sebring, the new Grand Sport duo aims to blend the modern mid-engine Corvette with its heritage. The Grand Sport X just takes that formula and firmly plants it in supercar territory. It also effectively steps in as the successor to the hybrid all-wheel-drive Corvette E-Ray.

The entire car revolves around GM’s brand-new small-block V8, called the LS6. The naturally aspirated 6.7-liter (409-cu-in) unit becomes the standard engine not just for Grand Sport, but for the 2027 Stingray as well. Chevrolet says the engine produces 535 hp (399 kW) and 520 lb-ft (705 Nm) of torque, making it the torquiest naturally aspirated V8 ever put in a Corvette from the factory.
The new engine features a 13.0:1 compression ratio, forged internals, a revised lubrication system, and a tunnel-ram intake with a 95-mm throttle body. Power goes to the rear wheels through an eight-speed dual-clutch transmission, keeping the traditional rear-drive layout intact for the standard Grand Sport.
As expected, the Grand Sport is still the middle ground between the Stingray and the more extreme Z06 and ZR1 models. Magnetic Ride Control is standard, while optional packages add stiffer suspension tuning, Michelin Pilot Sport 4S or Cup 2R tires, carbon-ceramic brakes, and additional aero.
Both Grand Sport variants also adopt a wider body similar to the Z06, giving them a more planted stance and added grip.
Don’t Call It A GSX
The new Grand Sport X (for sure don’t shorten that to GSX… right Buick?) is big news too. Like the E-Ray and ZR1X before it, this variant has an electric motor that powers the front wheels. That front motor produces 186 hp and 145 lb-ft (197 Nm), and works with a compact lithium-ion battery mounted within the chassis. Combined output jumps to 721 hp (538 kW), with the electric motor alone delivering instant torque to the front axle for improved traction and acceleration.
Like other electrified Corvettes, the system allows limited electric-only driving at low speeds, while track modes such as Endurance, Qualifying, and Push-to-Pass manage how the battery deploys power. In other words, the GSX, erm, Grand Sport X has all the ingredients of a hardcore car with the added benefit of AWD traction when needed. That’ll come in handy against several of the world’s supercars.
Quiet Running, Serious Stopping
There’s also a new Stealth mode that lets the car glide along silently on electric power at speeds of up to 50 mph (80 km/h), ideal for slipping through the neighborhood without waking anyone. If that still feels a bit too brisk, Shuttle mode dials things back further, limiting the car to 23 mph (37 km/h), again without firing up the V8.
Carbon-ceramic brakes come standard on the Grand Sport X, further separating it from the regular model.
Grand Sport Styling
Chevrolet leaned heavily into Grand Sport history for the design, with signature hash marks, heritage colors, and new forged or carbon-fiber wheel options. Admiral Blue returns, and Launch Edition cars get a Santorini Blue interior with red accents and unique trim details. For the first time, the signature hash marks are positioned on the rear fenders, subtly changing a long-standing design cue.
The revived nameplate also signals how important this part of the lineup is. Chevrolet says the Stingray and Grand Sport models together are expected to make up the bulk of Corvette sales, making the new LS6 engine the true backbone of the range. Production of the 2027 Corvette Stingray, Grand Sport, and Grand Sport X begins this summer at Bowling Green.
The Grand Sport X is set to reach dealerships later this year, and pricing is expected to climb past the outgoing E-Ray’s $108,600 starting figure before destination fees.
