Ryan Hunter-Reay won for the second consecutive race in Iowa.
The drama began before the race had even started as pole sitter Dario Franchitti pulled off with a blown engine.
Championship leader Will Power joined him in retirement early on after his spotter failed to warn him about EJ Viso on his inside and the pair tangled. Power initially thought he’d just control of his car until he saw the replay.
Helio Castroneves led the early stages but an early pit stop let Scott Dixon into the lead. Ryan Briscoe assumed the lead after Dixon pitted but went out shortly afterwards in a collision with Josef Newgarden.
That left Dixon in the lead for the final stint but he had the Andretti cars of Hunter-Reay and Marco Andretti bearing down on him. Both got past him and Tony Kanaan also demoted the Ganassi driver for third.
The race came to an early end with four laps to go when Katherine Legge crashed out. Dixon ended up fourth ahead of Simon Pagenaud, who recovered brilliantly from starting last.
Here’s the highlights:
Hunter-Reay moves up to second, three points behind Power. Hinchcliffe missed out on a chance to take the lead when he crashed out following a late restart.
1. Will Power – 286
2. Ryan Hunter-Reay – 283
3. Scott Dixon – 271
4. Helio Castroneves – 261
5. James Hinchcliffe – 256
6. Simon Pagenaud – 246
