Dario Franchitti won his second IndyCar Series championship, putting a disappointing foray into NASCAR in 2008 behind him.

Franchitti took his Chip Ganassi Racing Dallara-Honda to victory at Long Beach, Iowa Speedway, Toronto and Infineon Raceway in a season long battle with his Chip Ganassi teammate Scott Dixon and Team Penske driver Ryan Briscoe.

The only other winner was Justin Wilson, scoring Dale Coyne Racing's first victory at Watkins Glen.

Brazilian racer Raphael Matos claimed rookie of the year honors for the Luczo-Dragon Racing team, finishing thirteenth in the season point score, 29 points clear of Robert Doornbos with a season best result of sixth at Milwaukee.
