The writing is on the wall: A new Corvette is coming. There have been several leaks picked up by Corvette super sleuths that tell us that, without a doubt, GM is cooking up something special. The circulating rumors seem toall agree that it's a Corvette Grand Sport. Previously, there wasn’t much to confirm this is actually the case. But that just changed when a C8 Corvette with interesting body lines and those signature stripes was spotted in what appears to be a film shoot. C8 Grand Sport Sighted While Filming An Instagram user with the handle njp_moto uploaded a video capturing a glimpse at a peculiar C8 Corvette he spotted on the side of the road. The car is outfitted with an aggressive body kit and features four exhaust tips located in the center of the rear valance. At first glimpse, you might think it's a Z06, but those Heritage stripes scream “Grand Sport.”One detail that throws a wrench in the spokes is the location of the stripes. In the past, the Grand Sport has had two signature stripes located on the front fenders. The one sighted in the video has them on the rear quarters. While a strange creative choice, it doesn’t really derail the excitement.GR Auto Gallery The body kit and exhaust setup shared with the Z06 makes perfect sense, too. These cars are historically built using the Z06 suspension with a lower-tier drivetrain to create a more affordable performer. While we only get a brief look at the car, this does appear to be exactly what a C8 Grand Sport would look like in the minds of Corvette enthusiasts.What adds weight to the fact that this is a Corvette Grand Sport is the fact that it was surrounded by what seems to be a film crew. Not the kind you’d see filming a privately-owned vehicle, either. There was an RV, a box truck, and a van, along with multiple other vehicles, including a second C8, and work stations for crew members. A production of this standard suggests they may have been filming for an official announcement. Expect A New Corvette Unveil Soon Chevrolet Of course, there have been no comments from GM regarding this sighting, meaning this chalks up to more evidence pouring from the rumor mill. That said, it comes on the heels of a slip-up in the Corvette parts book that detailed the development of a new 6.7-liter V8 engine, which would fit right at home in a C8 that’s meant to sit as a mid-tier performance model. In any case, we won’t have to wait long to get the official details if the C8 in the clip turns out to be the real deal.
