Here is a test drive video with John Hennessey at the helm of the 2011 Hennessey ZR750 Corvette - based on the ZR1.
Hennessey himself is happy to tell us about the car and its boosted supercharger as he takes it for a spin around the tuner's own facility where the car can legally be pushed way past those pesky American speed limits.
The kit that Hennessey adds to the ZR1 puts a total of 755 bhp (563 kW / 765 PS) on tap, making this ZR750 good for a 0 to 60 mph (96 km/h) sprint run of 2.8 seconds.
