2007 Peak Antifreeze Indy 300

The 2007 Peak Antifreeze Indy 300 was a race in the 2007 IRL IndyCar Series, held at Chicagoland Speedway. It was held over the weekend of 7 -September 9, 2007, as the seventeenth and final round of the 2007 calendar.

Dario Franchitti secured the title after title rival Scott Dixon ran out of fuel, some 800 metres shy of the line. After this race, Franchitti moved on to the NASCAR Sprint Cup, meaning that for the first time in IRL history, a champion would not defend his title in the following season.
