The Veyron features an 8.0 litre W16 engine — 16 cylinders in two banks of eight cylinders, or the equivalent of two narrow-angle V8 engines mated in a “W” configuration. Each cylinder has four valves for a total of 64, but the narrow staggered 8 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 mm by 86 mm (3.4 in × 3.4 in) bore and stroke. Bugatti Veyron Grand Sport

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. This is designed and manufactured by Ricardo of England (and not Borg-Warner who designed the six-speed DSG used in the mainstream marques of the Volkswagen Group). The Veyron can be driven in either semi-automatic or fully automatic mode. A replacement transmission for the Veyron costs just over $120,000. It also features full-time permanent four-wheel drive, using the Haldex Traction system. It uses special Michelin PAX run-flat tyres, designed specifically for the Veyron to accommodate its top speed, which reportedly cost $25,000 US per set.[7] The tires can only be removed from the rims in France, a service which reportedly costs $70,000. Kerb weight is 2,034.8 kilograms (4,486 lb).[7] This gives the car a power to weight ratio, according to Volkswagen Group’s 736 kilowatts (1,001 PS; 987 bhp) figures, of 446.3 bhp per ton.
