Chevrolet is fitting its mid-engine Corvette C8 with a new naturally aspirated V8.
The 6.7-liter LS6 V8 unveiled this week replaces the outgoing 6.2-liter LT2 outright, representing a generational change rather than a bolt-on upgrade.
The move is being framed as a defining update that reshapes performance and character across the Corvette lineup.
New 6.7L LS6 engine
More power and better efficiency

The LS6 is rated at 542 horsepower and 705 N·m (about 520 lb-ft) of torque.
Both output and torque rise over the LT2, and the compression ratio jumps from 11.5:1 to 13.0:1.
Chevrolet has also moved from pure direct injection to a combined injection strategy to boost both efficiency and performance.
The design keeps a traditional overhead-valve layout while integrating modern hardware and controls.
Grand Sport returns as the lineup’s new middle ground

The LS6 will anchor a revived Grand Sport model.
Positioned between the base Stingray and the track-focused Z06, the Grand Sport aims to blend daily usability with genuine track capability.
It uses the Z06’s widebody architecture but is tuned for a more practical, road-friendly balance, and it’s expected to be a key volume and performance seller for the lineup.
The Grand Sport name, rooted in Corvette’s racing history, makes a return.
Hybrid expansion
Up to 731 horsepower available

Chevrolet will also introduce an all-wheel-drive hybrid variant called the Grand Sport X.
A front-mounted electric motor paired with the LS6 engine produces a combined system output of up to 731 horsepower.
Positioned to replace the Corvette E-Ray, the Grand Sport X pushes both performance and electrification while preserving the car’s naturally aspirated V8 character.
Analysts say the strategy lets Corvette keep the emotional appeal of a combustion V8 while staking out a distinct position in an electrifying sports-car market.
