Briton Dario Franchitti coasted to a second Indianapolis 500 win in four years Sunday, claiming victory after a spectacular crash ended the race under caution. Fighting to conserve fuel, Franchitti was able to cruise home with arms raised in triumph after compatriot Mike Conway's car launched into the fence and disintegrated, bringing out the yellow flag with one lap to go. In both his 500 wins, Franchitti crossed the finish line unchallenged. His first victory at the famed speedway came under caution in a rain-shortened race in 2007. The Scotsman Franchitti delivered a flawless drive in scorching conditions to become just the 17th man to register two 500 victories. Dan Wheldon made it a British one-two when he crossed second for the second consecutive year. A third Briton in Alex Lloyd appeared to have completed the podium until race officials awarded Marco Andretti third place after reviews showed the American had slowed for the pace car when the yellow flag came out and was passed by several cars. With victory secured, Franchitti jumped out of his car into the arms of his actress wife Ashley Judd and chugged from the traditional bottle of milk in Victory Lane, even as the crowd at the far end of the speedway watched quietly when Conway was removed from the mangled cockpit of his demolished car. Conway was examined at the speedway clinic and then airlifted to hospital but officials said his injuries were not life-threatening. Franchitti's win earned team owner Chip Ganassi a unique 500 double as the first man to win the United States' two biggest races, the Daytona and Indy 500, in the same year. Marco Andretti was moved up to third more than two hours after the race when IndyCar officials ruled Alex Lloyd, Scott Dixon and Danica Patrick did not have the right to pass Andretti as the field strolled to the finish. Alex Lloyd moved down one spot to fourth. Scott Dixon moved from fourth to fifth, and Danica Patrick dropped from fifth to sixth after the league nullified the passes they made after the caution flag came out on Lap 199. Officials also flipped the order of 13th and 14th. Mario Romancini moved up one spot to 13th, while Simona de Silvestro fell to 14th.
