“Grand Sport has always been the Corvette for drivers who want the spirit of a race car in a package they can enjoy every day,” said Scott Bell, vice president of Global Chevrolet. “With the new Grand Sport and Grand Sport X, we’ve taken that formula into the mid-engine era, pairing a heritage-rich design with the most advanced Corvette technologies we’ve ever offered. The Grand Sport model has historically acted as a high-volume player in the Corvette lineup. We expect the Stingray and Grand Sport lineup combined to account for the vast majority of Corvette sales.”

The 2027 Corvette Grand Sport and Grand Sport X will use the next-generation LS6 6.7L V8, which now becomes Corvette’s primary engine, powering the 2027 Stingray as well. Rated by Chevrolet at 535 horsepower and 520 lb.-ft. of torque, “this naturally aspirated engine sees increases in power and torque across the rev band compared to its predecessor. A larger 6.7L (409 cu in) displacement and 13.0:1 compression ratio improve response. The 95-mm throttle body and tunnel ram intake with high-velocity ports move more air to provide additional power. A new lubrication system, forged pistons and rods, and revised exhaust manifolds ensure durability in extended high-load, high-temperature environments,” Chevrolet said in a release. An eight-speed dual-clutch transmission routs power to the wheels.
