Just that little bit of an edge over the Z06.
The Z06 version of the C7 Corvette is obviously a mighty impressive machine, but Hennessey Performance offers an alternative to the car which has an undeniable appeal. Hennessey's version has a 2.3-liter supercharger, high flow heads, new cams, new engine management and some aero tweaks. The result is 708 horsepower, a 2.9-second 0-60 mph time and a quarter mile time of 10.97 seconds, all of which is just a bit better than the Z06.
You can see the car, which even comes with a 3-year warranty, working out at the drag strip in the following video.
