Lewis Hamilton and Nico Rosberg repeatedly trade places at the top of the order as Valtteri Bottas goes third fastest with 1:211.296.
Ten minutes to go and 14 drivers have got at least one timed lap under their belts, still waiting for ones from the Ferraris, but the good news is that they have indeed managed to get Kimi Raikkonen out.

Felipe Nasr sets the initial pace with a 1:23.400 but Valtteri Bottas swiftly improves on that with 1:22.622.
Meanwhile, there's an engine firing up in the Ferrari garage. It looks like Kimi Raikkonen could be getting out, despite an exhaust problem in final practice.

Tom Clarkson
BBC F1 pit-lane reporter"As for cut off times it is really difficult to predict because conditions are changing all the time. Cars are out on medium tyres and still doing their homework. Based on what we know so far it looks like the cut off time will be 1:21.9."
