A privileged potential customer of the all-new Bugatti Grand Sport Vitesse was invited to test drive the world's fastest roadster, which was unveiled back in March at the Geneva Motor Show.

The test drive took place on and around the Paul Ricard Circuit in southern France, and the cars used for the test drives were the actual models unveiled in Geneva. The Bugatti Grand Sport Vitesse features a 8.0-liter W16 engine with four enlarged turbochargers. The monstrous output of 1,200hp and 1,106lb-ft of torque allow the open-top French automobile to hit a staggering 258mph and sprint from 0-60mph in 2.5 seconds. It sits on lightweight 20-inch bespoke wheels and features aerodynamic parts from the Super Sport.

A new front spoiler, larger air intakes on the front-end and a double diffuser in the rear along with centrally-positioned dual tailpipes are highlights of its added attributes. The most powerful roadster ever is rumored to cost around £2,000,000, but whether this lucky punter decided on parting with such a huge sum of money for the car is unknown. If he did, let's hope he went for the gorgeous grey.
