The2007 Peak Antifreeze Indy 300 was a race in the2007 IRL IndyCar Series, held atChicagoland 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 rivalScott Dixon ran out of fuel in turn 3 of on the final lap, some 800 metres shy of the finish fine. After this race, Franchitti moved on to theNASCAR Sprint Cup Series, meaning that for the first time in IRL history, a champion would not defend his title in the following season. Franchitti returned to IndyCar in2009 and would go on to win three straight Indycar championships from 2009 to 2011 and two Indy 500s in 2010 and 2012. Before he retired following a crash in the second race of the2013 Shell-Pennzoil Grand Prix of Houston.
Another notable farewell was2006 Indy 500 winner & three timeIndy Racing League championSam Hornish Jr. as he would also move in 2008 to theNASCAR Sprint Cup Series withTeam Penske. Unlike Franchitti, Hornish never came back to IndyCar since then. More significantly this was the last Indycar race of the "split era " which had begun in1996as the IRL would merge with Champ Car for 2008 creating unified Indycar series once more.
