A pre-production 2027 Chevrolet Corvette Grand Sport has been spotted in Michigan. Photos suggest the new model will slot between the Stingray with the Z51 package and the Z06.

The prototype features wide body panels and a quad-center exhaust setup like the Z06, though the rear bumper shows cutouts for side exhaust outlets. The rear window is camouflaged, likely to conceal a new engine.

According to a leak from GM's parts catalog in December 2025, the next-generation naturally aspirated engine might be designated LS6 with a displacement of 6.7 liters, up from the current LT2's 6.2 liters. It is expected to use both direct and port fuel injection, potentially replacing the LT2 in Stingray and E-Ray versions over time.

The test car also rides on carbon wheels similar to the Z06. Rumors of a possible manual transmission are considered unlikely by experts, as the C8 platform was originally designed for the Tremec dual-clutch automated manual gearbox.

The Corvette Grand Sport traditionally focuses on balancing power and handling, so this model could appeal to those eyeing 2026 sports cars and seeking a middle ground between base and track-focused variants. An official debut is anticipated soon.
