“Following a thorough review conducted with a number of external experts, Guinness World Records is pleased to announce the confirmation of Bugatti’s record of Fastest production car achieved by the Veyron 16.4 Super Sport. The focus of the review was with respect to what may constitute a modification to a car’s standard specification. 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,” said Guinness World Records.
The Bugatti Veyron SS achieved a record top speed of 267.856 mph (431.072 km/h) back in 2010, but most production cars are sold with a 258 mph (415 km/h) electronic speed limiter for safety reasons.
