Corvette enthusiast site CorvetteBlogger recently captured an entourage containing seven experimental Chevrolet Corvettes and two competitive cars—a Jaguar F-type SVR and a Dodge Challenger Hellcat—stopping to refuel near Marietta, Ohio.

At least one top Corvette program manager was in attendance, and the fleet included both coupe and convertible examples of the 2018 ZR1 we expect to appear in January at the North American International Auto Show in Detroit. As we’ve previously reported, the ZR1 likely will be the last hurrah for the C7 generation, with an estimated 750 horsepower locked and loaded under the hood. After a short run, it will give way to the mid-engined C8 Corvette.

We’ve also embedded a video captured by one of the site’s readers, so you can hear the edgy but deeply guttural soundtrack that will have Corvette fans reaching reflexively for their wallets.
