The last hour of practice before qualifying saw continual changes at the top of the leader board as Ferrari, McLaren and BMW proved closely matched, and Anthony Davidson starred again for Super Aguri.

Raikkonen was the first of the leading drivers to take to the track, lapping in 1:33.480 after 19 minutes.

Massa and Hamilton went second and third shortly afterwards, each setting fastest sector times but not stringing a complete lap together.

Both drivers improved later on their first runs, as Massa went fastest on 1:33.307, while Hamilton improved to second, 0.149 seconds behind the Ferrari.

Raikkonen went off at Turn 13 as he tried to respond, but five minutes later he retook the top spot with a 1:33.231.

The second runs saw more place-swapping, as Massa reclaimed first place, three tenths clear of Raikkonen, moments before Hamilton beat the Brazilian by 0.028 seconds.

But Ferrari and McLaren were then usurped by BMW, as with 12 minutes remaining Nick Heidfeld produced two laps good enough to lead the session, and Robert Kubica moved up to complete a team one-two.

Massa looked set to retake first position until he came across yellow flags for Scott Speed's Toro Rosso, which had parked trackside on the exit of Turn 10. He continued and was about to go quicker still until he ran wide onto the sand at the final corner.

Raikkonen avoided such errors and went fastest with a 1:32.549, but seconds later Hamilton crossed the line with a time six-thousandths faster, which stood as the best of the session.

Behind Hamilton, Raikkonen and the BMWs, Davidson took fifth with a stunning late lap in the Super Aguri, ahead of Massa and Fernando Alonso, who had a low key session and ended the hour seven tenths of a second slower than his teammate.

Mark Webber was eighth for Red Bull despite going off the road at Turn 11, ahead of the two Renaults, who were both running with heavy fuel loads in order to test brake wear in race conditions.

It was an eventful morning for the four Red Bull-owned cars, as in addition to Speed's problem and Webber's error, Vitantonio Liuzzi nearly left the garage with a tyre blanket still attached to his car, and David Coulthard slowed to a crawl on track in the final minutes.
