Chevrolet has unveiled the 2027 Chevrolet Corvette Grand Sport and the new Corvette Grand Sport X, reviving a well-known nameplate while introducing GM’s new LS6 6.7L naturally aspirated V8. Positioned as a middle ground within the Corvette range, the Grand Sport returns with a focus on combining everyday usability with track-oriented capability.
Both variants are powered by a newly developed 6.7-litre (409ci) naturally aspirated V8, producing 399kW (535hp) and 705Nm. That’s the highest torque of any naturally aspirated V8 production engine Chevy has made. The unit also becomes the standard engine across the updated Chevrolet Corvette Stingray range.
The sixth-gen V8 features a high compression ratio of 13.0:1, and uses a 95mm throttle body to feed the intake, as well as forged pistons, and direct and port injection. Chevrolet says the engine will make its way across to other models with GM’s umbrella in the near future, which means it’ll likely be headed to Australia at some point.
For the Grand Sport, it continues the traditional rear-wheel drive approach, pairing the V8 with an eight-speed dual-clutch transmission. Standard features include adaptive suspension and all-season tyres, with optional performance packages introducing stiffer chassis tuning, upgraded braking systems and more track-focused tyres.
Sitting above that, the Grand Sport X adds an electrified all-wheel-drive system like the Corvette E-Ray, combining the V8 with a front-mounted electric motor. Total system output rises significantly to 538kW, while also enabling short bursts of electric-only driving at low speeds. Chevrolet says the setup is designed to improve traction and acceleration without compromising the balance expected from a mid-engine platform.
Both models carry over familiar Grand Sport design cues, including heritage-inspired colour combinations and signature striping, although these have been adapted to suit the current-generation layout. The wide stance and mid-engine proportions remain.
Inside, there is a series of bespoke finishes for launch versions, alongside continued emphasis on a driver-focused cockpit and dash. Material upgrades and customisation options are also expanded, particularly for early production examples.
Alongside the new Grand Sport variants, Chevrolet has confirmed updates for the broader Corvette lineup. The Stingray adopts the LS6 V8, along with revisions to suspension tuning and performance packages aimed at improving responsiveness.
Production of the 2027 Corvette range, including the Grand Sport and Grand Sport X, is scheduled to begin mid-2026 in the United States. Any Australian details are yet to be confirmed.
