The 2007 IRL IndyCar Series began with a night race on Saturday March 24 at Homestead-Miami Speedway. The season's premiere event, the 91st Indianapolis 500 was held May 27. The season finale was held at Chicagoland Speedway on September 9. Dario Franchitti, who won four races during the season, including the Indy 500, clinched the 2007 IndyCar Series Championship on the final lap of the final race, by winning the race after points leader Scott Dixon ran out of fuel while leading with less than ⅓ of a lap to go.
