What engine powers the 2027 Corvette Grand Sport?
The 2027 Chevrolet Corvette Grand Sport introduces an all-new 6.7-liter LS6 naturally aspirated small-block V8, producing 535 horsepower and 520 lb-ft of torque. Displacing 409 cubic inches, the LS6 features a 13.0:1 compression ratio and combines direct and port fuel injection.Chevrolet says its 520 lb-ft output represents the highest torque produced by a naturally aspirated V8 in a production vehicle, giving the Grand Sport substantial performance without relying on turbocharging or supercharging.
The standard Grand Sport pairs the LS6 with an eight-speed dual-clutch transmission and rear-wheel drive. Buyers seeking even more performance can step up to the Grand Sport X, which combines the same 6.7-liter V8 with an electric motor powering the front axle. That setup creates electric all-wheel drive and increases combined output to 721 horsepower, giving Chevrolet two distinct versions of the Grand Sport formula: a traditional naturally aspirated, rear-wheel-drive model and a substantially more powerful electrified variant.

What is the difference between Grand Sport and Grand Sport X?
The 2027 Chevrolet Corvette Grand Sport and Grand Sport X share the same naturally aspirated 6.7-liter LS6 V8 and eight-speed dual-clutch transmission, but their drivetrains create two distinctly different performance models. The standard Grand Sport sends 535 horsepower to the rear wheels, maintaining a more traditional Corvette layout. The Grand Sport X adds a 186-horsepower electric motor at the front axle, creating electric all-wheel drive and increasing combined output to 721 horsepower.
That electrification gives the Grand Sport X a substantial advantage in straight-line acceleration and traction, with estimated 0-to-60-mph times of roughly 2.4 to 2.7 seconds. Buyers pay considerably more for that additional performance, however. The rear-wheel-drive Grand Sport is expected to start around $88,000, while the Grand Sport X coupe begins at approximately $112,000. The standard Grand Sport therefore targets buyers seeking naturally aspirated, rear-wheel-drive performance, while the Grand Sport X adds hybrid-assisted acceleration and all-wheel-drive traction for those wanting the more potent configuration.
