DETROIT — Chevrolet is reviving one of Corvette’s most storied racing names with the 2027 Corvette Grand Sport, and creating new legacy with the Grand Sport X.
Both vehicles blend heritage-inspired design with a next-generation V8 engine that produces more torque than any other naturally aspirated V8 before it, Chevy officials noted in a release posted to the carmaker’s website. The duo delivers a modern take on Grand Sport’s traditional role as a sweet-spot in the lineup, blending visceral V8 performance, distinctive style and everyday drivability.
Born in the early 1960s as a limited run of five C2 race cars that competed at tracks like Sebring International Raceway, Grand Sport has long stood for lightweight, track-focused Corvettes that look as fast as they drive. Road-going Grand Sport models have added to the formula of the name every generation by pulling features from the fastest cars in each Corvette generation, while maintaining heritage colors, distinct striping, and signature fender hash-marks that once served as ways to tell the original race cars apart.
Today’s Grand Sport lineup reflects the best of what the eighth-generation Corvette has to offer, including a wide, planted mid-engine stance, an interior that elevates driver cockpit design, and the benefits of either a removable-roof coupe or hardtop convertible. Plus, standard Magnetic Ride Control, available Performance Traction Management, and so much more.
“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.”
Next Generation 6.7L LS6 V8
At the core of every 2027 Corvette Grand Sport and Grand Sport X is the next-generation LS6 6.7L V8, which now becomes Corvette’s primary engine – powering the 2027 Stingray as well. Launching General Motors’ next generation of V8s, LS6 raises the bar for performance thanks to engine architecture upgrades that will soon benefit other V8-powered Chevrolets.
Delivering 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 sharpen response, while a 95-mm throttle body and tunnel ram intake with high-velocity ports move more air to unlock additional power.
A new lubrication system, forged pistons and rods, and revised exhaust manifolds ensure durability in extended high-load, high-temperature environments.
“There is no replacement for displacement! Our next generation LS6 engine pushes 409 cubic inches of jackhammer fury through the tailpipes,” said Mike Kociba, assistant chief engineer, Next Generation V8. “Combining large displacement, modern technology, and proven Small Block V8 heritage will deliver a bold new chapter in performance.”
An eight-speed dual-clutch transmission routs all this power to the wheels.
GM’s Flint Engine Operations in Flint, Michigan will assemble the LS6 with US and globally sourced parts, returning production to the city where the first Corvette V8s were built in 1955.
