Austin (Texas): Sauber`s Esteban Gutierrez was hit with a 10 place grid penalty for the US Formula One Grand Prix after impeding Williams driver Pastor Maldonado during qualifying on Saturday.
The Mexican, who had qualified 10th for Sunday`s race, will now start 20th after stewards ruled he had "unnecessarily impeded" the Venezuelan just minutes into the session at the Circuit of the Americas.
The stewards also said in a statement that the rookie had performed manoeuvres they considered to be dangerous.
Marussia`s Max Chilton was handed a drive-through penalty for impeding in the same session and must serve it during the first five laps of Sunday`s race, the penultimate round of the season.
The Briton had qualified in last place but Caterham`s Charles Pic, who was one place above, was handed a five-place grid penalty for an unscheduled gearbox change on Friday.
