Overview
- An unannounced example ran a parade lap at the 12 Hours of Sebring alongside prior Grand Sport generations, showing a widebody, quad center exhausts, new splitter and rear lip spoiler, black wheels and red calipers.
- Chevrolet confirmed a March 26 unveiling and said the car will introduce “the next generation of GM V8 technology,” signaling the public debut of GM’s Gen VI small-block.
- Reporting points to a naturally aspirated 6.7-liter LS6 V8 for the Grand Sport with output in the mid-500 hp range, though final specifications remain unconfirmed.
- Multiple outlets and dealer/Instagram leaks suggest a Grand Sport X hybrid may replace the E-Ray by pairing the new V8 with the E-Ray’s front motor for all-wheel drive and roughly 720 hp combined, which has not been officially verified.
- Coverage indicates the Grand Sport will slot between the Stingray and Z06 in performance, and The Drive notes the C8 lineup is not expected to add a manual transmission.
