For the second year in a row the Indianapolis 500 was decided in a hugely dramatic moment on the final lap.
Takuma Sato launched a bold attack on Dario Franchitti for the lead at the beginning of the last lap, but spun out and crashed.
The race had seen a record-breaking number of lead changes up to that point. Heading into the final caution period Tony Kanaan held the lead, but was passed by the two Ganassi cars of Franchitti and Scott Dixon.
The two red cars continued to swap the lead until Sato split them with two laps to go, before launching his unsuccessful attack on Franchitti. He was classified 17th.
Franchitti fought back from dead last early in the race having been hit by EJ Viso during his first pit stop.
A nasty crash early in the race eliminated series leader Will Power and Mike Conway – and forced Helio Castroneves to take avoiding action to miss hitting a flying wheel:
Franchitti won the Indianapolis 500 for the third time, becoming the tenth driver to do so. Unusually, all three have come under caution on the last lap.
Franchitti needs one more to reach the record tally of four held by AJ Foyt, Al Unser and Rick Mears.
After the race Franchitti paid tribute to Dan Wheldon, thanking the fans at the track for taking part in tributes to him during the race weekend.
