Coming into the last double-points race of the IndyCar season at the Laguna Seca track in Sonoma, California, it was expected to be a battle between Juan Pablo Montoya and Graham Rahal – who sat 1-2 in the season points standings – for the 2015 IndyCar Championship. But Scott Dixon had other plans. Dixon not only won the race and claimed the double points that came along with it – he beat Montoya, Rahal and pole-sitter Will Power to do it. Dixon was 47 points down entering the final race and his win actually tied him with Montoya for the season championship but Dixon claims the trophy on the tiebreaker – he had three season wins to Montoya’s two. It was the fourth IndyCar championship of Dixon’s career.
Montoya eventually finished sixth after a mid-race collision with Power.
