what is the top speed of bugatti veyron super sport
Bugatti Veyron The Super Sport version of the Veyron is recognised 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).[7] Hennessey Performance Engineering made the Venom GT with a 4.238 km/h (2.633 mph) faster than the Veyron Super Sport, but the 2014 run was in only one direction, so it was not recognized by Guinness. 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.[8][9] The Venom GT Spyder is 18.6 km/h (11.56 mph) faster than the Veyron Grand Sport Vitesse, but the 2016 run was a one-direction run, so it was not recognized by Guinness.
Production car speed record On 4 July 2010 the Bugatti Veyron Super Sport reached 431.072 km/h (267.856 mph) two-way average. Bugatti built 30 Super Sports (5 of them named World Record Edition). At the time the record was set it was known that the customer cars were electronically limited to 415 km/h (257.87 mph). Guinness Book of Records (which had listed speeds by British cars with modified rev limiter as production car records in the 1990s) listed the unlimited 431.072 km/h (267.856 mph) as production car speed record. Yet, 3 years later, after a query by the Sunday Times Guinness' PR director Jaime Strang was quoted: "As the car’s speed limiter was deactivated, this modification was against the official guidelines. Consequently, the vehicle’s record set at 431.072 km/h is no longer valid." 5 days later it was written on its website: "Guinness World Records would like to confirm that Bugatti's record has not been disqualified; the record category is currently under review." 5 days later Bugatti’s speed record was confirmed: "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."[1][4][5]
Production car speed record The current Guinness World Records title holder, the Bugatti Veyron Super Sport, was certified for the average top speed achieved on a two-way run, registering 431.072 km/h (267.856 mph). Bugatti made 5 Veyrons named the World Record Edition out of the initial production run of 30 Super Sports, all of which would be able to achieve this speed if the limiter was removed. With the limiter the Veyron SS goes 415 km/h (257.87 mph). Bugatti did not sell any with the limiter removed. Initially, when challenged by Hennessey, Guinness decided the Bugatti was ineligible because the test car was deemed as being modified. Bugatti sought a review of the decision and Guinness, after a review by a panel of experts, considered removing the limiter was not a modification and thereby making the car eligible for their publication.[2] To this day, even though the Bugatti Chiron is believed to have a top speed of around 463 km/h (288 mph), it is not verified, and with the limiter it has a non-verified top speed of 261 mph (420 km/h). As of August 2017[update], the Veyron SS is still classified as the fastest production car in the world.
Formula One Formula One cars are the fastest road course racing cars in the world, owing to very high cornering speeds achieved through the generation of large amounts of aerodynamic downforce. The cars underwent major changes in 2017,[4] allowing wider front and rear wings, and wider tyres, resulting in cornering forces closing in on 8g and top speeds of up to approximately 375 km/h (230 mph).[5] The hybrid engines are currently limited in performance to a maximum of 15,000 rpm and the cars are very dependent on electronics—although traction control and other driving aids have been banned since 2008—and also on aerodynamics, suspension, and tyres.
