Fastest Production Street Car
 

The Bugatti Veyron 16.4 is a mid-engine sports car produced by Volkswagen AG subsidiary Bugatti Automobiles SAS introduced in 2005. It is the quickest accelerating and decelerating road-legal production car in the world, and it was the world's fastest car until it was beaten by the SSC Ultimate Aero TT in 2007. Powered by a 1,001 PS (987 hp/736 kW) W16 engine,[2] it is able to achieve an average top speed of 408.47 km/h (253.81 mph).[3] The car reached full production in September 2005, and is handcrafted in a factory Volkswagen built near the former Bugatti headquarters in Château St Jean in Molsheim (Alsace, France). 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.

The SSC Aero is an American- built automobile. Its higher-performance limited production version, the SSC Ultimate Aero TT,[1] is currently the fastest production car in the world, with a highest recorded speed of 413 km/h (257 mph).[2] This speed was reportedly achieved during tests on September 13, 2007 in West Richland, Washington, United States and verified by Guinness World Records on October 9, 2007.[3] During one test, the car almost fell apart as a result of the poor build quality. The Ultimate Aero's acceleration is 0-60 mph in 2.78 seconds, taking it a bit more than that of former top-speed record holder the Bugatti Veyron.

The Aero and the Shelby Super Cars company are the brainchildren of Jerod Shelby, who spent over seven years designing the car. Only twenty-five Aeros are to be produced[citation needed] and it is unclear how many will be the Ultimate model.[citation needed] The basic Aero model is priced from $239,000, while, as of 2007, the Ultimate Aero is likely to cost well over $650,000
