Bugatti Veyron - Super car

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).

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 Veyron's chief designer was Hartmut Warkuss, and the exterior was designed by Jozef Kabaň 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.

Bugatti Veyron 16.4 Engine

The Veyron 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 Veyron can be driven in either semi- or fully automatic mode. A replacement transmission for the Veyron 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 Veyron'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.

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:

• 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),and a frontal area of 2.07 square metres (22.3 sq ft).This gives it a drag area – the combination of drag coefficient and frontal area, represented as C_dA – of 0.74 m² (8.0 sq ft).

The Veyron Super Sport features an engine power increase from the standard 1,001 metric horsepower (736 kW; 987 bhp) to 1,200 metric horsepower (883 kW; 1,184 bhp) and torque of 1,500 N·m (1,100 ft·lbf) and a revised aerodynamic package. It was shown publicly for the first time at the Pebble Beach Concours d'Elegance in August 2010.

Bugatti's official test driver Pierre Henri Raphanel drove the Super Sport version of the Veyron on Volkswagen's Ehra-Lessien high-speed test track to establish the car's top speed. With representatives of the Guinness Book of Records and German Technical Inspection Agency (TÜV) on hand, Raphanel made passes around the big oval in both directions achieving an average maximum speed of 431.072 km/h (267.856 mph). Once produced for sale, the first five Super Sports will sport the same black and orange finish as the first production car, which was used to set the speed record, and all production models will be electronically limited to 415 km/h (258 mph) to protect the tyres.

Improved aerodynamics kit, 1,200 metric horsepower (883 kW; 1,184 bhp) 1,500 newton metres (1,100 ft·lbf) torque engine upgrade. It has a 431.072 km/h (267.856 mph) top speed, making it the fastest road car in production, although it is electronically limited to 415.07 km/h (257.91 mph) to protect the tyres from disintegrating. The first five of an unannounced production run made its debut in a matte black and orange colour combination, all of which have been spoken for. The public debut was at the Pebble Beach Concours d'Elegance in August 2010. It is valued at GB£1.7 million and Bugatti have stated that only 30 will be produced.
