Guinness returns fastest production car world record to Bugatti

The Bugatti Veyron Super Sport is back as the “Fastest Production Car” after Guinness World Records looked deeper into the claim, and decided that Bugatti's eliminating the speed limiter in order to set a record did not bar the vehicle from holding the title. “The focus of the review was with respect to what may constitute a modification to a car's standard specification,” said Guinness in a statement. “Having evaluated all the necessary information, Guinness World Records is now satisfied that a change to the speed limiter does not alter the fundamental design of the car or its engine.” Now the company owns both the open- and closed-top speed records with the Veyron Grand Sport Vitesse and the Veyron Super Sport.

Sporting the same 650bhp as the Lamborghini Reventon, the LP650-4 Roadster is the last of the line of open-topped Murcielagos (apart from the Reventon Roadster – which as there will only be 9 doesn’t really count), and is the successor to the LP640 Roadster.
