A sleek motor has smashed the record for the world's fastest accelerating car, managing a speed of 300km/h in an eye-watering 13.63 seconds.

The Hennessey Venom GT is a Texan-built supercar powered by a 7-litre V8 engine developing a whopping 1,244bhp.

It demonstrated its muscle and power in Houston, USA, where the car was taken for a spin.

The Venom GT raced from 0-300kph in 13.63 seconds - the same time it takes a diesel Ford Fiesta to hit 100km/h.

Guinness World Records verified the time had been snatched from the previously fastest Koenigsegg Agera which managed 0-300km/h in 14.53 seconds - almost a second longer.

The £910,000 ($1,366,510 AUD) supercar also managed 0-320km/h in a supersonic 14.51 seconds - a staggering 7.7 seconds quicker than the Bugatti Veyron Super Sport.

The Venom GT did 0-160km/h in 5.88 seconds and after one-mile had reached 329km/h.

John Hennessey, founder of Hennessey Performance, revealed he was going after the record for top speed, which is currently held by the 431km/h Veyron Super Sport.

But the firm will have its work cut out to find somewhere to hit this speed - with Bugatti having special access to Volkswagen’s Ehra-Lessien 60 mile test track in Germany.

He said: "We are exceptionally proud of our team at HPE who helped to make this new Guinness World Record possible.

"It was a great moment, but this is just the beginning and we plan to set a few more speed records as part of our Venom GT validation process.

"We are in the process of looking for a runway or toll road long enough to make some top speed runs.

"A flat four mile stretch of road would be ideal and we’re confident the Venom GT will do 270mph-plus 434km/h)."
Hennessey plans to build just 29 Venom GTs with each model taking six months to build.

The firm has sold ten models so far with Aerosmith frontman Steve Tyler owning a convertible edition.
