The newly launched Hennessey Venom GT has been taken to the British streets (near the Silverstone race track) for a short testing season. The Venom GT is powered by a supercharged 6.2 liter LS9 V8 engine that delivers a total of 725 bhp (but the tuner is also offering 1000 bhp and 1200 bhp twin turbo V8 engine variants). With a curb weight of less than 2,400 lbs, the Venom GT will hit a top speed of 200 mph.
