Chevrolet is set to overhaul the Corvette lineup in 2027 with the introduction of a new 6.7-liter V8 engine and two high-performance variants: the track-focused Grand Sport and the hybrid Grand Sport X. The move marks a significant shift in the C8 Corvette’s engine options, with the larger displacement V8 becoming the primary powertrain for the iconic sports car.
New Engine and Performance Specs
The 2027 Corvette Grand Sport will feature a 6.7-liter LS6 V8, the largest engine ever fitted to a C8 Corvette. This naturally aspirated powerhouse delivers 393kW (527 horsepower) and 705Nm (519 lb-ft) of torque—the highest torque output for any naturally aspirated Corvette V8. The engine boasts a 13.0:1 compression ratio, a 95mm throttle body, and a combination of direct and port fuel injection for optimized performance.
The Grand Sport X, meanwhile, is a hybrid variant that replaces the E-Ray. It combines the new 6.7-liter V8 with a front-axle electric motor to produce a combined output of 538kW (720 horsepower), exceeding the E-Ray’s 488kW (654 horsepower). Both models utilize an eight-speed dual-clutch automatic transmission.
Track and Hybrid Options
Chevrolet has positioned the Grand Sport as a “true driver’s Corvette,” emphasizing its rear-wheel drive configuration and naturally aspirated V8. The Grand Sport will be available with optional performance packages, including the Z52 Track Performance Package, which adds carbon-ceramic brakes, Michelin Pilot Sport Cup 2R tires, and aggressive aerodynamic enhancements.
The Grand Sport X offers all-wheel drive, standard carbon-ceramic brakes, and a higher overall power output. Both models will be available in classic striped liveries and a range of colors, with the Grand Sport receiving Pearl Nickel 20-inch and 21-inch wheels wrapped in Michelin Pilot Sport All Season 4 tires.
Impact on the Corvette Lineup
The introduction of the 6.7-liter V8 will also extend to the entry-level Stingray, which will receive retuned magnetic ride control and an optional Z51 Performance Package with a shorter final drive and upgraded tires. The move underscores Chevrolet’s commitment to continuously refining the Corvette’s performance capabilities.
The current C8 Corvette lineup has evolved since its 2020 debut, with additions such as the Z06, E-Ray, and ZR1. Chevrolet’s latest announcement further expands the range, offering buyers more choices in terms of power, performance, and driving experience.
Chevrolet expects the Stingray and Grand Sport combined to account for the vast majority of Corvette sales. Production is set to begin in mid-2026, with no immediate announcements for availability in the ANZ region.
The 2027 Corvette’s upgrades demonstrate Chevrolet’s dedication to pushing the boundaries of performance while preserving the Corvette’s legacy as an iconic American sports car.
