The Bugatti Veyron EB 16.4 is a mid-engined grand touring car. The Super Sport version is the fastest road-legal production car in the world, with a top speed of 431 km/h (268 mph). The original version has a top speed of 408.00 km/h (253.52 mph). It was named Car of the Decade (2000?2009) by the BBC television programme Top Gear.
Bugatti Veyron SS, Designed and developed by Volkswagen Group (based on the Bentley Hunaudieres concept) and produced by Bugatti Automobiles SAS at their headquarters in Château Saint Jean in Molsheim (Alsace, France), the Bugatti Veyron SS's chief designer was Hartmut Warkuss, and the exterior was designed by Jozef Kaba? of Volkswagen, with much of the engineering work being conducted under the guidance of former Peterbilt Trucks engineer and now Bugatti Engineering chief Wolfgang Schreiber. Though commissioned by Volkswagen, this car is only sold through the Bugatti manufacturers and cannot be found at any Volkswagen dealer.
A number of special variants have been produced, including two targa tops. In December 2010, Bugatti began offering prospective buyers the ability to customize exterior and interiors colours by using the Bugatti Veyron 16.4 Configurator application on the marque's official website.
The car is named after French racing driver Pierre Veyron, who won the 24 hours of Le Mans in 1939 while racing for the original Bugatti company. The 16.4 refers to 16 cylinders and 4 turbochargers.
The Bugatti Veyron SS features an 8.0 litre, quad-turbocharged, W16 cylinder engine, equivalent to two narrow-angle V8 engines . Each cylinder has four valves for a total of sixty four, but the narrow staggered V8 configuration 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 (487.8 cu in), with a square 86 by 86 mm (3.4 by 3.4 in) bore and stroke.
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 Bugatti Veyron SS can be driven in either semi- or fully automatic mode. A replacement transmission for the Bugatti Veyron SS costs just over US$120,000. It also has permanent four wheel drive using the Haldex Traction system. It uses special Michelin PAX run-flat tyres, designed specifically to accommodate the Bugatti Veyron SS's top speed, which cost US$25,000 per set. The tyres can be removed from the rims only in France, a service which costs US$70,000. Curb weight is 1,888 kilograms (4,162 lb). This gives the car a power-to-weight ratio, according to Volkswagen Group's figures, of 446.3 metric horsepower (328 kW; 440 bhp) per ton.

German inspection officials recorded an average top speed of the original version of 408.47 km/h (253.81 mph) during test sessions on the Ehra-Lessien test track on 19 April 2005.
This top speed was verified by James May on Top Gear in November 2006, again at Volkswagen Group's private Ehra-Lessien test track. May noted that at top speed the engine consumes 45,000 litres (9,900 imp gal) of air per minute (as much as a human breathes in four days). The Bugatti Veyron SS has the highest top speed of any street legal production car. Back in the Top Gear studio, co-presenter Jeremy Clarkson commented that most super-cars felt like they were shaking apart at their top speed, and asked May if that was the case with the Bugatti Veyron at 407 km/h (253 mph). May responded that no, the Bugatti Veyron SS was very controlled, and only wobbled a tiny-bit when the air-brake deployed. May further commented ?Absolutely yeah, it?s totally undramatic. But I would give you a bit of a warning, It?s a bit disorientating doing that sort of speed, because after I came off the banking, I was slowing down to stop, and you know how you get a bit impatient and think ?I?ll just open the door?, fortunately I looked back at the speedo, and I was still doing seventy.?
On 4 July 2010, Bugatti's official test driver Pierre Henri Raphanel piloted the Super Sport edition and was clocked at an average of 431.072 km/h (267.856 mph) on the same track, taking back the title from the SSC Ultimate Aero TT as the fastest production vehicle of all time. The 431.072 km/h mark was reached by averaging the Super Sport's two test runs, the first reaching 427.93 km/h (265.90 mph) and the second 434.20 km/h (269.80 mph). The record run was certified by the German government and the Guinness Book of World Records.
The Bugatti Veyron SS's everyday top speed is listed at 350 km/h (220 mph). When the car reaches 220 km/h (140 mph), hydraulics lower the car until it has a ground clearance of about 9 cm (3.5 in). At the same time, the wing and spoiler deploy. In this handling mode the wing provides 3,425 newtons (770 lbf) of downforce, holding the car to the road.
For top speed mode the driver must, while at rest, toggle a special top speed key to the left of the driver's seat. A checklist then establishes whether the car and its driver are ready to attempt to reach 407 km/h (253 mph). If so, the rear spoiler retracts, the front air diffusers shut, and normal 12.5 cm (4.9 in) ground clearance drops to 6.5 cm (2.6 in).
