Helio Castroneves will be forced to drop back to 11th on the grid for Sunday's IndyCar race at Iowa Speedway after Penske elected to change the Brazilian's engine.
Castroneves had initially claimed pole by winning the third heat race on Saturday evening, but he will incur a 10-place penalty for having a new Chevrolet unit installed. Teammate Will Power will be promoted onto pole, although Castroneves keeps the nine points that he earned for the heat race win, and will still start ahead of closest title rival Ryan Hunter-Reay.
The Penske driver's penalty was based upon a rule that requires drivers to use up the engine that was changed to fit the fresh Indianapolis 500 engine if that engine is reinstalled before the Indy engine has reached its minimum mileage.
Castroneves is one of four drivers facing grid penalties for engine changes, with penalties also having been applied to Scott Dixon – who had qualified fifth – James Jakes and Josef Newgarden.
All of those three will be sanctioned for the more common rule breach of changing an engine before it has reached its minimum 2,000-mile threshold.
