This is yet another review of the Hennessey Venom GT, which is now tested on public roads. Apart from the driving test, we also get a closer look at the Venom GT's inner workings, thanks to one of Hennessey's officials. The Venom GT recently managed to get a Guinness World Record for a 0-300 km/h (186mph) acceleration test. The Hennessey Venom GT is based on a Lotus and it's powered by a monster 6.2 liter V8 engine that spits out 1,200 hp.
