Specifications and performance
The Veyron features a 16 cylinder engine , equivalent to two narrow-angle V8 engines mated in a W configuration. 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 bi-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 Veyron can be driven in either semi- or fully-automatic mode. A replacement transmission for the Veyron costs just over $120,000. It also has permanent four wheel drive using the Haldex Traction system. It uses special Michelin PAX run flat tires, designed specifically to accommodate the Veyron's top speed, which reportedly cost $25,000 U.S. per set.[8] The tires can be removed from the rims only in France, a service which reportedly costs $70,000. Curb weight is 2,034.8 kilograms (4,486 lb).[8] This gives the car a power to weight ratio, according to Volkswagen Group's 1,001 metric horsepower (736 kW; 987 bhp) figures, of 446.3 metric horsepower (328 kW; 440 bhp) per ton.
The car's wheelbase is 2,710 mm (106.7 in). Overall length is 4,462 mm (175.7 in), width 1,998 mm (78.7 in) and height 1,204 mm (47.4 in).
The Bugatti Veyron has a total of ten radiators.[9]
- 3 heat exchangers for the air-to-liquid intercoolers.
- 3 engine radiators.
- 1 for the air conditioning system.
- 1 transmission oil radiator.
- 1 differential oil radiator.
- 1 engine oil radiator.
It has a drag coefficient of 0.41 (normal condition) and 0.36 (after lowering to the ground),[10] and a frontal area of 2.07 square metres (22.3 sq ft).[11] This gives it a drag area – the combination of drag coefficient and frontal area, represented as CdA - of 0.74 m2 (8.0 sq ft).
