"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."
There’s been a lot of hubbub recently surrounding the claim to the "world’s fastest production car" title. After holding the record for nearly three years now, the Bugatti Veyron Super Sport was stripped by the Guinness World Record authorities of its title when challengers asserted that, because the commercially-available version was fitted with a speed limiter that the record-setting car was not, it was not qualified to claim the record. Guinness, however, has now stepped in to set the record straight.
After consulting with experts in the field, the Guinness officials proclaimed that "a change to the speed limiter does not alter the fundamental design of the car or its engine." And so the Veyron SS is once again anchored as the fastest production car in the world, having reached a top speed of 257.87 mph. In the midst of all the controversy, Bugatti also reasserted its claim on the record for the world’s fastest open-top car when the Veyron Grand Sport Vitesse roadster reached 254 mph. So no matter how you take your Veyron, it’s bound to be the fastest.
