Kerr quickest in practice on home soil

In a session that was stopped twice, the Team GBR driver set a 1:14.891 best in the final moments of the hour, eclipsing that of China's Congfu Cheng - who was running in a new Zytek engine.

Team USA's Jonathan Summerton was third quickest ahead of championship leaders Switzerland, with Neel Jani at the wheel.

Mexico race-winner Adam Carroll was fifth fastest for Team Ireland, with India's Narain Karthikeyan sixth.

The two red flags were caused by Indonesia, when Satrio Hermanto went off at Paddock, and Czech Repbublic's Filip Salaquarda, who also went off the track.
