2013 Iowa Corn Indy 250

The race was the tenth round of the 2013 IndyCar Series season, and was won by James Hinchcliffe of Andretti Autosport.

Castroneves also won the pole position after winning the qualifying heat race, but IndyCar officials ruled that Castroneves and his team had an improper engine change, changing engines before it ran the minimum 2,000 miles (3,218 km).

Because of this, Penske teammate Will Power was given the pole, with James Hinchcliffe in second, Marco Andretti in third and Ed Carpenter in fourth, taking Scott Dixon's spot, who was also penalized for improperly changing engines.

[3] Defending race winner Ryan Hunter-Reay failed to advance out of the preliminary heat.

[1] Simon Pagenaud, Oriol Servia, Hélio Castroneves, Marco Andretti, and E. J. Viso closed out the top ten.
