Sydney: The Guinness World Records has stripped the Bugatti Veyron Super Sport that "set" the fastest speed for a production car in 2010, of that title.
In confirming its decision, GWR said it discovered that the car used to set the world record of 431.072 kilometres per hour had been modified and as a result it had breached the rules, reports the Sydney Morning Herald.
UK-based newspaper Sunday Times has claimed a speed restrictor on the Veyron had been deactivated on the record-setting car in July 2010 which is seen as a key difference from the 30 cars sold to public.
Jaime Strang, GWR's PR director, said in a statement that there was an oversight in its adjudication of the ''Fastest production car'' which was set in 2010 by the Bugatti Veyron 16.4 Super Sport. He said the car's speed limiter was deactivated and this modification was against the official guidelines.
GWR's rules state that the car that sets the record must be mechanically identical to those on sale to the public. The speed restrictor on production Veyrons apparently lowers its top speed from 431 km/h to 415 km/h - for safety reasons.
The issue came to light last week when US sports car maker, Hennessey, questioned the Veyron's claim, pointing to the restrictor and claiming its own Venom GT was actually the fastest after it posted 427 km/h at a US Naval air base in California recently.
That record, however, was not set under official world record conditions which require an average speed to be set over two timed runs. Bugatti said it was standing by its world record and it would be seeking clarification.
