  • The Chevrolet Corvette Grand Sport returns in 2027.
  • It launched with General Motors’ next-generation LS6 V8 engine producing 535 horsepower and 520 pound-feet of torque.
  • The 721-horsepower Grand Sport X replaces the E-Ray while packing a new hybrid powertrain.

The Chevrolet Corvette Grand Sport is returning in 2027. The automaker teased the model earlier this month, but now we have almost all the details.

The Corvette Grand Sport will be powered by General Motors’ next-generation V8 engine, the LS6. The naturally aspirated 6.7-liter V8 produces 535 horsepower and 520 pound-feet of torque, and will also be the standard engine on the 2027 Stingray.

Chevrolet says the LS6 has forged pistons and rods, a revised exhaust manifold, and a new lubrication system. It has a 13.0:1 compression ratio, a 95-millimeter throttle body, and a “tunnel ram intake.”

The engine is combined with an eight-speed dual clutch transmission. The Gand Sport comes standard with Magnetic Ride Control, a touring suspension, and Michelin Pilot Sport All Season 4 tires. The automaker does not provide performance statistics for the new Corvette. Chevy will also offer the car with an optional center exit exhaust.

Chevrolet is also launching the Grand Sport X for 2027, replacing the E-Ray. The GSX is equipped with a new LS6 engine, which Chevy paired with a front-axle electric motor and battery from a Corvette ZR1X, producing 186 hp and 145 lb-ft of torque.

Combined output is 721 hp, topping the E-Ray’s 66 hp. The GSX is also more powerful than the Z06, which has a 5.5-liter naturally aspirated V8 engine that produces 670 hp. The X will also represent models that have eAWD, such as the ZR1X.

The GSX comes standard with Magnetic Ride Control, carbon-ceramic brakes, and Michelin Pilot Sport All Season 4 tires. The Performance Pack adds Michelin Pilot Sport 4S tires.

Chevy will also offer a Grand Sport Launch Edition featuring a Santorini Blue interior and red contrast stitching. It will have embossed headrests, speaker plaques, and steering wheel badges.

The automaker didn’t say when the 2027 Corvette Grand Sport will go on sale, but it is expected to start arriving at dealers this summer. Price is also still a mystery.

The Grand Sport sits between the entry-level Stingray, which starts at just over $70,000 for 2026, and the Z06 at $121,000. The 2026 E-Ray retails for around $110,000, so a new Grand Sport could sell for around $90,000.

We’ll have more details closer to its on-sale date.
