For decades, the Chevrolet Corvette has represented an uncompromising vision of American performance. Iconic, bold, and endlessly evolving, it now appears ready to embrace a new era that nods proudly to its past.
According to reports from GM Authority, the upcoming Corvette Grand Sport may debut with an all-new 6.7‑liter LS6 V8 engine. That means big displacement, traditional pushrods, and the kind of mechanical muscle that evokes the golden age of sports cars. This engine is believed to be part of GM’s sixth generation of LS powerplants, slated for introduction around 2027.
The engine is expected to first appear in GM’s heavy-duty trucks before reaching performance icons such as the Corvette. If true, the new Grand Sport would occupy a unique position—bridging the gap between the accessible Stingray and the electrified power of the E-Ray, delivering pure, naturally aspirated performance enriched by modern engineering.
Though official figures remain unconfirmed, early indications suggest that the Grand Sport could produce about 600 horsepower. This output would neatly position it between the Stingray’s traditional V8 and the forthcoming ZR1’s twin-turbo 5.5‑liter LT7 flat-plane engine.
Estimated pricing between $70,000 and $110,000 would make the Grand Sport an appealing choice for drivers seeking a blend of affordability and track-ready dynamics without crossing into the ultra-premium supercar bracket.
Based on current projections, the introduction of GM’s next-generation LS engines aligns with a 2027 launch window. The company’s trucks would likely adopt the platform first, followed by performance models like the Corvette.
For long-time enthusiasts, the idea of a big naturally aspirated V8 returning to the Corvette signals more than just another model year—it symbolizes a revival of sound, soul, and driving purity. In an age of hybrid and electric performance, Chevrolet appears poised to prove that progress can also mean embracing its mechanical roots.
