Watch: Hennessey GT sets world record

The video below is the result of adding 7.0-litres of V8 muscle to 1,244kg of modified Lotus Exige, via the rear wheels and lots of bravery. It is of course, the Hennessey Venom GT, and it's just set a new world record.

But you already know this, because we told you last week. Today, we can give you footage from the record-breaking run, which saw the seventh production Venom GT - packing 1244bhp and 1155lb ft of torque - power from 0-300km/h in just 13.63 seconds.

"This is just the first of several validation tests designed to show the world what our special car is all about - being the fastest, period," said John Hennessey. A chap named John Kiewicz drove the Venom along Ellington Airport's runway in Texas, the same runway used by NASA, no less. And after the record-breaking runs, the Guinness adjudicator on hand - Philip Roberston - was given a special hotride.

"I have never ridden in anything this fast," Philip noted. "The acceleration is absolutely amazing." Quite. The 13.63s time was an average of two runs made in opposite directions: the first took 13.18 seconds, while the second took 14.08 with a 6mph headwind.

That's not all - we're told the car also set an unofficial 0-200mph time as well, 14.51 seconds. To add some context, the Koenigsegg Agera R did the same sprint in 17.68 seconds, while the Bugatti Veyron ran 0-200mph in 22.2 seconds. Woah.
