What do you do when Chevy hands you the keys to a 2015 Corvette Stingray and an open run at the Milford Road Course? You flog it for all you’re worth, whether you know the track or not.

That’s just what we did yesterday.

Of course, this wasn’t your usual 7-speed manual Stingray. Nor was it the old 6-speed automatic. No, for 2015, the Stingray gets an all-new, GM-designed and built 8-speed automatic that it claims will slay Porsche’s PDK dual-clutch.
