The Bugatti Veyron EB 16.4 is a mid-engined sports car, designed and developed in Germany by the Volkswagen Group and manufactured in Molsheim, France, by Bugatti Automobiles S.A.S.
The original version had a top speed of 407 km/h (253 mph).
The current Super Sport version of the Veyron is recognized by Guinness World Records as the fastest street-legal production car in the world, with a top speed of 431.072 km/h (267.856 mph), and the roadster Veyron Grand Sport Vitesse version is the fastest roadster in the world, reaching an averaged top speed of 408.84 km/h (254.04 mph) in a test on 6 April 2013
A controversy developed in 2013 over the Veyron Super Sport’s status as the world’s fastest production car, ultimately resolved in the Veyron’s favor.
In early April 2013, driving.co.uk (also known as Sunday Times Driving) began an investigation following claims from US car maker Hennessey that its 928 kW (1,244 bhp)Hennessey Venom GT was entitled to the Guinness World Record. With a recorded speed of 427.6 km/h (265.7 mph) the Hennessey was 3.4 km/h (2.1 mph) slower than the Veyron but Hennessey dismissed Bugatti’s official record saying that the Veyron Super Sport was restricted to 415 km/h (258 mph) in production form and that for it to achieve its record top speed of 431.0 km/h (267.8 mph), the car used was in a state of tune not available to customers. Hennessey said its Venom GT was road-ready and unmodified and was therefore a production car in the strict sense of the term.
Driving.co.uk requested clarification from Guinness World Records, which investigated this claim and found that the modification was against the official guidelines of the record. Upon finding this, Guinness World Records voided the Super Sport’s record and announced it was “reviewing this category with expert external consultants to ensure our records fairly reflect achievements in this field.”
After further review, Shelby SuperCars, the producers of the Ultimate Aero TT, said that they had reclaimed the record, however Guinness reinstated the Super Sport’s record after coming to the conclusion that “a change to the speed limiter does not alter the fundamental design of the car or its engine.”
