2027 Chevrolet Corvette Grand Sport and Grand Sport X join C8 Lineup

At Sebring last week, General Motors, in a surprise move, previewed a new Grand Sport Corvette based on the C8. Finished in heritage-inspired Admiral Blue with red and white accents, it appeared alongside historic models, hinting at what was coming next. Now, General Motors has officially revealed the 2027 Corvette Grand Sport. Alongside it comes an all-new Grand Sport X, a hybrid variant that replaces the E-Ray and expands the Corvette lineup in a meaningful way. This is the first time the Grand Sport badge has been applied to a mid-engine Corvette, marking a major moment in the model’s history. The name traces back to 1963, when Chevrolet built five lightweight race cars to compete internationally. It later returned on the C4, skipped the C5, and then found its modern identity on the C6 and C7. In those generations, the Grand Sport became known as the most balanced Corvette, combining the base engine with Z06-level chassis upgrades and wider bodywork. For 2027, that formula evolves with a new powerplant with an all-new LS6 small block, a 6.7-liter naturally aspirated V8 that produces 535 horsepower and 520 pound-feet of torque. This engine replaces the outgoing 6.2-liter LT2 that offered 495 horsepower, and now serves as the standard powertrain for the entry-level Stingray as well, representing the most significant update to the base Corvette since the C8 launched in 2020.  The Z06 will continue to deliver 670 horsepower from the LT6 5.5-liter flat-plane V8. At the top, the ZR1 and ZR1X utilize a turbocharged version of that engine, i.e., the LT7, pushing up to 1,064 horsepower. The Grand Sport, with its LS6 output, fits directly between these models, reinforcing its role as the most balanced Corvette. The increase in displacement on this new LS6 comes from a longer stroke, paired with a larger throttle body and a redesigned intake system. The engine also runs a higher 13.0:1 compression ratio and features dual injection, combining direct and port systems for improved performance and efficiency. Internally, it uses forged components, improved oiling, and revised cooling to handle increased loads. The Grand Sport remains true to its core identity as a rear-wheel-drive, naturally aspirated driver’s car. Standard Magnetic Ride Control, touring suspension, and Michelin all-season tires ensure everyday usability. A touring setup prioritizes comfort, while sport and optional track-focused packages introduce more aggressive tires, braking systems, aerodynamic elements, and Michelin Pilot Sport Cup 2R tires. The Grand Sport X expands the formula with electrification. Pairing the LS6 with a front-mounted 1.9 kWh electric motor, it produces a combined 721 horsepower through an all-wheel-drive system. For some context, the outgoing E-Ray hybrid offered 655 horsepower. The setup enhances traction and corner-exit performance while maintaining the mid-engine platform's balance, with selectable performance modes including Endurance, Qualifying, and Push-to-Pass. This model replaces the E-Ray and integrates hybrid performance more directly into the Corvette lineup. Visually, the Grand Sport leans heavily into heritage while embracing the proportions of the mid-engine platform. The stance is wider and more planted, with Z06-derived bodywork, staggered wheels, and available carbon-fiber aero that includes a front splitter, dive planes, side rockers, and a prominent rear wing. Signature hash marks move from the front fenders to the rear for the first time, a direct nod to the engine now sitting behind the cockpit. Admiral Blue returns alongside new finishes like Pitch Gray Metallic. Inside, the cabin builds on the C8’s driver-focused layout with a more expressive execution. A Launch Edition introduces a Santorini Blue-dipped interior with red stitching and accents across nearly every surface. Headrests feature embossed Grand Sport graphics, while the center spine and driver display hood carry matching red detailing. An asymmetrical Santorini Blue and black interior is also available, adding another layer of personalization. Production begins this summer, with the Grand Sport expected to start under $90,000,  with the Grand Sport X most likely near the $100k mark, placing it squarely in the middle of the Corvette range. The Stingray starts around $75,000 where as the Z06 range starts around $120k. The result is a lineup that feels more structured than ever. The Stingray evolves with a new engine, the Grand Sport continues to define balance, and the Grand Sport X introduces a new layer of hybrid performance, all built around the same mid-engine architecture.

Chevrolet Unveils 2027 Corvette Grand Sport in Surprise Sebring Reveal

Chevrolet Unveils 2027 Corvette Grand Sport in Surprise Sebring Reveal

This past weekend, GM unveiled the 2027 Corvette Grand Sport in a surprise appearance at the 12 Hours of Sebring, marking the return of one of the most important names in Corvette history, a driver-focused model that bridges the gap between accessibility and high-performance. The unannounced debut caught enthusiasts and insiders off guard, reinforcing the American automaker’s deep connection to endurance racing and its own heritage. This debut carries added weight through its connection to Roger Penske, who served as Grand Marshal for the 74th Mobil 1 Twelve Hours of Sebring IMSA race, where Porsche Penske Motorsport secured a 1-2 finish, with the #7 Porsche 963, running a special Mobil 1 livery during the event, claiming the team’s 20th overall victory in Florida. But long before building one of the most successful teams in motorsport, Penske competed at Sebring in 1964 alongside Jim Hall, securing a class victory in a Corvette Grand Sport, helping establish the car’s reputation following its development under Zora Arkus-Duntov, who is considered the Father of the Corvette. “It is an incredible opportunity to be reunited with the Corvette Grand Sport C2 here at the Twelve Hours of Sebring – an event and a track that has always carried special meaning for me and for our race teams over the years. Congratulations to Chevrolet on launching the new era of the Grand Sport program. It is truly special to see the C2 and the other generations of the Corvette Grand Sport, including the new C8, here at Sebring.” - Roger Penske  For the occasion, Chevy also brought together the full Grand Sport lineage, including the original C2 race car from 1963, the 1996 C4 tribute, and later C6 and C7 variants, positioning the new C8 as a direct continuation of that bloodline. Visual elements such as the Admiral Blue finish, white center stripe, and red hash marks also served as a direct reference to this heritage, while the widened stance reflects the C8 platform’s modern architecture. The 2027 Grand Sport also marks a major milestone as the first mid-engine Grand Sport, built on the C8 Corvette platform. This shift introduces a new level of balance and performance while preserving the core identity that has defined the badge for decades. Within the current Corvette range, base Stingray and E-Ray models pack a 6.2-liter LT2 cross-plane V8 producing 495 horsepower. The Z06 moves to a 5.5-liter flat-plane LT7 delivering 670 horsepower, while the ZR1 and the ZR1X employ a turbocharged version of that engine producing 1,064 horsepower and 1,250 horsepower, i.e., the most powerful Corvette ever made. As for the C8 Grand Sport, rumors point to an all-new naturally aspirated V8 delivering performance in the 500 to 550 horsepower range, paired with a widebody chassis and track-focused hardware. But we won't have to wait much longer, as Chevrolet will release full specifications this Thursday, on March 26. Watch this space. View All Chevrolet Corvettes for Sale  Images: General Motors
