The Porsche 911 GT3 was introduced in 1999 as a high performance version of Porsche's first version of the 911, the 996, to continue the quarter-century tradition of low-weight RS models that ended with the 993 RS. The GT3, named after the FIA GT class it was intended for, did not use the rather simple engine of the regular production versions of the 996, but a naturally-aspirated version of the turbocharged Porsche 962 and Porsche 911 GT1 race cars. Later, the turbo-charged Porsche 911 GT2 was added to the maker's lineup, but unlike its predecessor 993 GT2, did not fit into GT racing regulations. The racing versions of the GT3 have won several major 24h races outright, and mainly dominated their class at Le Mans.
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, it is able to achieve an average top speed of 408.47 km/h (253.81 mph). 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.
