The Audi R8 is a Le Mans Prototype sports-prototype race car introduced in 2000 for sports car racing as a redevelopment of their Audi R8R (open top LMP) and Audi R8C (closed top LMGTP) used in 1999. In its class it is one of the most successful racing sports cars having won the 24 Hours of Le Mans race in 2000, 2001, 2002, 2004, and 2005, five of the six years it competed in total. Its streak of Le Mans victories between 2000 and 2005 was broken only in 2003 by the Bentley Speed 8, another race car fielded that year by Volkswagen Group.
