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.
