Nigel Ernest James Mansell, CBE is a British racing driver who won both the Formula One World Championship and the CART Indy Car World Series. Mansell was the reigning F1 champion when he moved over to CART, becoming the first person to win the CART title in his debut season, and making him the only person to hold both titles simultaneously.
His career in Formula One spanned 15 seasons, with his final two full seasons of top-level racing being spent in the CART series. Mansell remains the most successful British Formula One driver of all time in terms of race wins with 31 victories, and is sixth overall on the Formula One race winners list behind Michael Schumacher, Alain Prost, Ayrton Senna, Sebastian Vettel and Fernando Alonso. He held the record for the most number of poles set in a single season, which was broken in 2011 by Sebastian Vettel. He was rated in the top 10 Formula One drivers of all time by longtime Formula One commentator Murray Walker. In 2008, American sports television network ESPN ranked him 24th on their top drivers of all-time. He was also ranked No. 9 of the 50 greatest F1 drivers of all time by the Times Online on a list that also included such drivers as Alain Prost, Ayrton Senna, Jackie Stewart and Jim Clark.
