Anthony Wayne "Tony" Stewart is an American auto racing driver, businessman and team owner. Throughout his racing career, Stewart has won titles in Indy cars and stock cars as well as midget, sprint and USAC Silver Crown cars.
Stewart currently owns and drives the No. 14 Bass Pro Shops/Mobil 1 Chevrolet SS in the NASCAR Sprint Cup Series for his own team, Stewart-Haas Racing under crew chief Chad Johnston. From 1999 until 2008, he drove the No. 20 Joe Gibbs Racing car, under crew chief Greg Zipadelli, with The Home Depot as the primary sponsor. His ten-year tenure with the same team, sponsor, and crew chief is a NASCAR record. Stewart is also the only driver to win both the Winston Cup under the old points system and the Nextel Cup under the chase playoff format, winning those championships in 2002 and 2005 respectively. In 2011, Stewart became the first owner-driver since Alan Kulwicki to win the Cup Series championship, which ended Jimmie Johnson's streak of consecutive championships at five. He is the only driver to win the NASCAR championship under three different sponsorship titles as well as being the only driver in history to win a championship in both IndyCar and NASCAR. He is also the first driver in Cup to win the championship by virtue of a tie breaker.
