Summary
- Chevrolet introduces the 2027 Corvette Grand Sport and the hybrid all-wheel-drive Grand Sport X
- Both models debut the new 6.7-liter naturally aspirated LS6 V-8 engine producing 535 horsepower
- The Grand Sport X replaces the E-Ray and boosts total output to 721 horsepower with an added electric motor
Chevrolet has officially revived the iconic Grand Sport nameplate for the 2027 model year, introducing two new additions to the C8 Corvette lineup. Slotted between the base Stingray and the track-focused Z06, the rear-wheel-drive Grand Sport and the all-wheel-drive Grand Sport X feature wider bodywork, upgraded suspension, and bigger brakes inherited from the Z06 and ZR1 models.
At the heart of both new Corvettes is the debut of a next-generation 6.7-liter LS6 V-8 engine. Replacing the outgoing LT2, this naturally aspirated small-block is packed with performance hardware, including a tunnel ram intake, forged internals, and a 13:1 compression ratio. The LS6 produces 535 horsepower and 520 lb-ft of torque, making it the most torque-heavy naturally aspirated V-8 in the model’s history. Power is routed exclusively through an eight-speed dual-clutch transmission.
The Grand Sport X model arrives as a direct replacement for the Corvette E-Ray. It combines the new LS6 V-8 with the front-axle electric motor and battery pack from the ZR1X, pushing the total combined output to a staggering 721 horsepower. The GSX also features standard carbon-ceramic brakes and exclusive track modes, making it an extreme all-weather performer. Official pricing has not been fully detailed, but the rear-drive Grand Sport is expected to start under $100,000 USD.
