How quickly can your car accelerate from 0 to 200 miles per hour? If you drive a McLaren F1, it takes 28.0 seconds. If you drive a Bugatti Veyron, it takes 24.2 seconds. The Koenigsegg Agera R is faster still at 17.6 seconds. In the 2013 Hennessey GT Venom Spyder, it takes just 15.3 seconds to hit 200 mph. But when your car costs $1.1 million dollars, you should expect no less.
As you can see, Hennessey Performance Engineering is all about big numbers.
