That's the questions being posed by UK-based Autocar in this video showing a 2009 Cyber Gray Corvette ZR1 going flat out through the English countryside in pursuit of the unknown chase car. With the narrow twisty roads, the ZR1 gives the thought of a pass now and again, but always backs off, but not before unleashing the 638 horses for a few seconds. Watch closely at the 1:53 mark as the ZR1 catches some serious air that lifts all four wheels off the road.
