BUGATTI CARS (SPEED RECORDER)

Bugatti

 The Bugatti is a mid -engine sports car, designed and developed in Germany by the Volkswagen Group and manufactured in Molsheim, France, by Bugatti Automobiles S.A.S.

 The Super Sport version is recognised by Guinness World Records as the fastest street-legal production car in the world, with a top speed of 430.9 km/h (267.7 mph), and the roadster  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.

 Several special variants have been produced. In December 2010, Bugatti began offering prospective buyers the ability to customise exterior and interior colours by using the Veyron 16.4 Configurator application on the marque's official website. The Bugatti Veyron was discontinued in late 2014.

 The Veyron features an 8.0-litre, quad-turbocharged, W16 cylinder engine, equivalent to two narrow-angle V8 engines bolted together. Each cylinder has four valves for a total of 64, but the V8 configuration of each bank allows two overhead camshafts to drive two banks of cylinders so only four camshafts are needed. The engine is fed by four turbochargers and displaces 7,993 cubic centimetres, with a square 86 by 86 mm bore and stroke.

 This top speed was equalled by James May on Top Gear in November 2006, at the Ehra-Lessien test track. May noted that at top speed the engine consumes 45,000 litres  of air per minute (as much as a human breathes in four days). Back in the Top Gear studio, co-presenter Jeremy Clarkson commented that most supercars felt like they were shaking apart at their top speed, and asked May if that was the case with the Veyron at 407 km/h (253 mph). May responded that the Veyron was very controlled, and only wobbled slightly when the air brake deployed.

 The transmission is a dual-clutch direct-shift gearbox computer-controlled automatic with seven gear ratios, with magnesium paddles behind the steering wheel and a shift time of less than 150 milliseconds, built by Ricardo of England rather than Borg-Warner, who designed the six speed DSG used in the mainstream Volkswagen Group marques. The Veyron can be driven in either semi-automatic or fully automatic mode.
