Video: Hennessey GT reaches 267.6mph in just one mile

Hennessey Performance - purveyors of mad, highly tuned performance cars - have made their mark on the history books, breaking the world speed record for the standing mile with the Hennessey GT.

The Ford GT-based creation managed to reach 267.6mph at the Texas Mile drag racing event - matching the terminal velocity of the world's fastest production car, the Bugatti Veyron Supersports.

And, unlike the ultra-exclusive Veyron, the Hennessy GT needed just the one mile to reach its top speed, whereas the Bugatti required the majority of VW's five-mile straight at its Ehra-Lessien test track in Germany.

Unusually, given the aerodynamic witchcraft needed to reach such high top speeds, the Hennessey GT's body looks relatively unmodified from the Ford model on which it's based (discounting the rear-mounted parachute of course).

The same can't be said of the engine. The Hennessey GT uses twin-turbocharging, in place of the standard cars supercharger, to force fuel (race grade for the record braking run) and air into its 5.7-litre V8.

Fitted with a manual gearbox and running in standard rear-wheel drive configuration, putting such awesome power down on the tarmac cleanly is as much testament to the driver (racer Sean Kennedy) as it is to the engineering behind this car.
