Sebastian Vettel pipped Mark Webber to the top time by less than five-hundredths of a second. Worryingly for their opponents, the two RB9s set their times early in the session while the track was still improving.
The closest of their rivals was Romain Grosjean, who lapped within 0.153s of Vettel’s time on his second run on soft tyres. Grosjean ran wide during his first effort having gone fastest in the middle sector.
Kimi Raikkonen might have been closer but all three of his runs on the soft tyre were spoiled by traffic. He caught Jenson Button in the final sector on one run, almost touching the McLaren as they went through the final corner.
The Ferrari pair took fourth and fifth ahead of the two Mercedes drivers. Raikkonen was eighth ahead of Button, with Adrian Sutil tenth.
Valtteri Bottas was called into the pits shortly before the end of practice with a KERS problem. Max Chilton was back in his Marussia after Rodolfo Gonzalez took his place in first practice, and had to pit due to a problem with his helmet which caused buffeting.
