Rosberg secured pole with his first run on medium tyres in Q3, posting a best time of 1:24.681.

The Manors were slowest once again, with Will Stevens in 19th position nearly a full three seconds behind Perez.
Spaniard Roberto Merhi finished nearly another second behind, and was unable to run for a second time due to a false alarm from his ERS.
