The Veyron Super Sport set the official record back in 2010 with a Guinness-verified speed of 267.8 miles per hour, but other interested parties have recently contested that record’s validity because the Veyron used that day had its speed limiter removed. With the speed limiter in place, the Veyron Super Sport tops out at 258 mph.
Guinness rules state that a record-setting production car must be unchanged from what is available to customers. While some, particularly Hennessey Performance, have claimed that removing the Veyron’s speed limiter violated that rule, Guinness has settled the matter by stating that “a change to the speed limiter does not alter the fundamental design of the car or its engine.”
This is a nice win for Bugatti on top of the news last week that the Veyron Grand Sport Vitesse also set a record for the fastest open-top production car with a speed of 254.04 mph. That record, however, as far as we know, has not been verified by Guinness World Records.
