John Hennessey is no stranger to the world of auto tuning. After all, he does have a company that’s considered as one of the best in the business. The company, Hennessey Performance Engineering is so good at what it does that it was actually able to build it’s own supercar based on the Lotus Elise: the Venom GT. Not a lot of tuners can stake the same claim, too.
In this particular video, John Hennessey is sitting behind the wheel of another one of his company’s creations, the 2011 Hennessey ZR750 Corvette. Based on the Corvette ZR1, the ZR750 was born from a special tuning kit the aftermarket company gave to the ZR1, one that nets the American sports car an improved engine output of 755 horsepower, an increase from the standard model’s 638 horsepower output. The increased power of the Hennessey ZR750 also translates to improved lap times, including a 0-60 mph time of just 2.8 seconds compared to the standard ZR1’s time of 3.4 seconds.
