A US supercar has become the world's quickest 0-300 kmh production car.
The Hennessey Venom GT set the record at Ellington Airport, near Houston, Texas, on January 10.

Guinness World Records (GWR) ratified the record with the street-legal Venom GT accelerating 0-300kmh in an eye-watering 13.63 seconds.
The acceleration time was an average of two runs made in opposite directions within one hour.
The car's first run was a searing 13.18 seconds with a 6 kmh tailwind while the second run was 14.08 seconds into a 9.6 kmh head wind for a 0-300 kmh average of 13.63 seconds.
"We are exceptionally proud of our team at HPE who helped to make this new Guinness World Record possible," company founder and president, John Hennessey, said.
"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."
GWR representative, Philip Robertson, witnessed the runs and inspected the car before all attempts and was later given a ride in the car.
"I have never ridden in anything this fast. The acceleration is absolutely amazing," Robertson said.
The vehicle was the seventh production Venom GT - a street-legal car that makes use of Michelin Pilot Sport Cup DOT-approved radial tyres, 93-octane pump fuel, and a full interior replete with high-end stereo, air conditioning, and bespoke leather / Alcantara seats
Powered by a 7.0-litre V8 engine fed by twin Precision turbochargers, the Venom GT produces 1244 horsepower and weighing just 1244 kg the rear-wheel-drive car delivers a power-to-weight ratio of 1 horsepower per each kilogram of vehicle curb weight.
Although Guinness only recognises runs made in kilometres per hour, the Venom GT also set a new unofficial acceleration record of 0-200 miles per hour in 14.51 seconds. The 0-200 mph record was previous held by the Koenigsegg Agera R that required 17.68 seconds time - 3.17 seconds slower than the Venom GT. By comparison, the Bugatti Veyron Super Sport (powered by a 1200 horsepower 8.0-litre, quad-turbocharged 16-cylinder engine channeling power through an all-wheel-drive system) ran 0-200 mph in 22.2 seconds - 7.7 seconds slower than the Venom GT.
While conducting the Guinness World Record runs, despite marginal traction (due to three days of previous rainfall), the Venom GT accelerated from 0-60 mph in 3.05 seconds, 0-100 mph in 5.88 seconds, ran the standing quarter-mile in 10.29 seconds at 158.83 mph, and ran the standing half-mile at 205.65 mph.
During testing done at Ellington Airport a few weeks prior to the Guinness® record runs, the Venom GT® accelerated to 300 km/h in 13.48 seconds while on its way to 370 km/h run (229.9 mph) in just 19.96 seconds.
Hennessey only plans to build a total of 29 Venom GTs, with one-third of the production run already being sold. The Venom GT costs US$1.2 million plus shipping and not including options.
Each vehicle is custom built to order and requires six months for completion.
