Behind Hamilton, who managed more laps than anyone else with 121, Fernando Alonso and Valtteri Bottas rounded out the top six, the latter sampling the new Williams FW35 for the first time.
Daniel Ricciardo, Paul di Resta and Nico Hulkenberg followed behind while at the bottom of the times, Max Chilton's Marussia managed to better the Caterham of Charles Pic despite the Briton bringing the session to an early end when he brought out the red flags when completing a planned fuel stoppage in the closing minutes.
“The work that we have been doing today is very important for improving some of the on-car systems but we've focused more on shorter runs and we weren't able to get into the tyre evaluation and set-up work that were part of my programme," Chilton said. "I did have the chance for one quick lap right at the end, which moved us ahead of Caterham on the timesheet, and that's why it would have been good to complete that part of the programme. It's been a good day in terms of what we have learned though as all data is good data at this important phase of our development.”
