A Texan-built supercar has set a new Guinness World Record title for the Fastest 0-300 km h by a production car, after hitting an incredible186mph in just 13.63 seconds.

Powered by a 7-litre V8 engine capable of an awe-inspiring 1,244bhp, the Hennessey Venom GT smashed the acceleration record during an attempt on Sunday at Ellington Field Airport runway in Houston, Texas.

With Guinness World Records adjudicator Philip Robertson on hand for the attempt, the car, which was piloted by test driver John Kiewicz, set an official time of 13.63 seconds - the average of two runs completed in opposite directions along the runway (the first 13.18sec with a 6.5km/h tailwind, the second 14.08sec with a 9.7km/h headwind).

Speaking after the attempt, John Hennessey, the boss of Hennessey Performance, 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," Hennessey explained.

'A flat four mile stretch of road would be ideal and we're confident the Venom GT will do 270mph-plus.'

Only 29 examples of the Hennessey Venom GT are set to be made, with a third of those having been sold already.

Each car takes six months to build and have an eye-watering price tag of £910,000,($1.44million), with Aerosmith singer Steven Tyler being among the exclusive group of owners.

However, potential buyers may want to note that the Venom GT's record-holding status may be short lived, with the California-based manufacturer already hard at work on the car's successor - the Hennessey Venom GT2, which is said to produce up to 1119kW of power.
