Chevrolet has unveiled details on the upcoming 2027 Corvette Grand Sport, which slots between the base Corvette and the high-performance Z06 model. The Grand Sport features a new naturally aspirated 6.7-liter LS6 V8 engine producing 535 hp and 520 lb-ft of torque, along with a range of suspension, wheel, and tire options to enhance its performance capabilities. While pricing has not yet been announced, the Grand Sport is expected to be positioned below the $100,000 mark, making it an attractive option for buyers seeking more power and capability than the base model without the extreme track focus of the Z06.

Why it matters

The Corvette Grand Sport is an important addition to Chevrolet's sports car lineup, providing a middle ground between the everyday usability of the base Corvette and the extreme performance of the Z06. This new variant allows Corvette buyers to get a balance of power, handling, and daily drivability, potentially appealing to a wider range of enthusiasts who want more than the base model but don't need the full track-focused capabilities of the top-tier Z06.

The details

The 2027 Corvette Grand Sport is powered by Chevrolet's latest iteration of the small-block V8, dubbed the LS6. This naturally aspirated 6.7-liter engine produces 535 hp and 520 lb-ft of torque, representing a 45 hp and 50 lb-ft increase over the previous-generation LT2 V8 in the base Corvette. To handle the higher piston speeds of the longer-stroke engine, the LS6 features forged pistons and connecting rods. The Grand Sport also benefits from larger throttle bodies and a higher 13:1 compression ratio compared to the 11.5:1 ratio of the LT2.

  • The 2027 Corvette Grand Sport is expected to launch later this year.

What they’re saying

“'There is no replacement for displacement,' said assistant chief engineer of the new engine Mike Kociba. 'Our next-generation LS6 engine pushes 409 cubic inches of jackhammer fury through the tailpipes. Combining large displacement, modern technology, and proven small-block V8 heritage will deliver a bold new chapter in performance.'”

With its new 535-hp LS6 V8 engine and a range of performance-enhancing options, the Grand Sport looks to be a compelling choice for enthusiasts seeking more than the base model without the full commitment of the top-tier Z06.
