The Bugatti Veyron 16.4 is currently the fastest, most powerful, and most expensive street-legal full production car in the world, with a proven top speed of 407.5 km/h (253 mph), though several faster or more expensive vehicles have been produced on a limited basis.[1] It reached full production in September 2005. The car is built by Volkswagen AG subsidiary Bugatti Automobiles SAS in its Molsheim (Alsace, France) factory and is sold under the legendary Italian/French Bugatti marque. It is named after French racing driver Pierre Veyron, who won the 24 hours of Le Mans in 1939 while racing for the original Bugatti firm.
