PWR cooled Scott Dixon has come back from 47 points in arrears on the final race to claim his fourth IndyCar Championship.
Juan Pablo Montoya had led the points after every race this season but with Dixon wining the final race on the 2.52 mile road course at Sonoma Raceway, the points were tied and Dixon won the Championship on a tiebreaker due to more wins in the season.
