Felipe Massa for Ferrari clocked up the fastest time in the morning session - despite missing the final 30 minutes of the session after crashing at Stowe corner at 180mph when his car hit oil – while McLaren's Heikki Kovalainen was fastest in the afternoon.

Kovalainen's team-mate, top British hope Lewis Hamilton, was third in both sessions.

Ferrari's Kimi Raikkonen was fourth in the morning, but struggled in the afternoon, only managing the 12th fastest time.

Brackley-based Honda will be pleased with British driver Jenson's button second practice time, which put him in seventh spot, 10 places higher than his morning session performance. Silverstone-based Force India-Ferrari again struggled to keep pace with the bigger teams.
