Scott Dixon won the Detroit Grand Prix on Sunday, giving the five-time champion his first win this year and the 45th of his career.
The Chip Ganassi Racing driver from New Zealand finished nearly 2 seconds in front of rookie Marcus Ericsson, Will Power, Ryan Hunter-Reay and Alexander Rossi.
The win was Dixon's first of the year after he had finished on the podium in four of the season's first seven races.
Indianapolis 500 champion Simon Pagenaud finished 17th after colliding with Patricio O'Ward and Tony Kanaan on the opening lap.
