Last week, Bugatti test driver, er, pilote official, Pierre Henri Raphanel set the production-car speed record in Bugatti’s new Veyron Supersports 16.4. The 1,200 horsepower, 1,106 pound-feet monster propelled Raphanel to timed runs of 265.9 and 269.8 mph on Volkswagen’s Ehra-Lessien test track near Wolfsburg, which according to the Guinness people, averages to a V-max of 267.81 mph. That’s more than enough to bring the title of world’s fastest production car back to the VW fold. We phoned the former F1 and Japanese touring-car driver to get his take on what it’s like to approach the 270 mph mark in a production car, why the forest is his friend and whether or not he’s up to try for 300.he 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 tyres, designed specifically to accommodate the Veyron's top speed, which reportedly cost €25,000 per set.[9] The tyres can be removed from the rims only in France, a service which reportedly costs €70,000. Curb weight is 1,888 kilograms (4,162 lb).[10] 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).
