Massa would go fastest with a 1m:20.490 but Sutil would take this spot with a 1m:20.394.

Rubens had taken to the track and was up to fourth with a 1m:21.003. Vettel was also out on the track and would move up to third with a 1m:20.812. With that the session would be stopped as a result of water appearing on the section of track where the grid is located. The problem was sorted out and the session restarted. For Webber his session would come to an end as he was to suffer a gearbox problem that would see his stuck in gear. With an hour of the session completed Hamilton would set the fastest first sector but would remain second to Massa. But Hamilton would set a 1m:18.136 to go fastest. But he would be beaten by Rosberg with a 1m:17.991. Rubens would move up to seventh with a 1m:19.741. More drivers were finding improvements with their times as Alonso went fastest with a 1m:17.619.

Alonso was fastest with Massa now second, Rosberg third, Hamilton fourth and Button fifth. Schumacher was sixth with just over twenty minutes remaining, ahead of Rubens in seventh, Buemi eighth and Kovalainen ninth. Hamilton would find further improvements to go fastest with a 1m:17.350. Vettel was now seventh and Sutil eighth. Massa would again lower the quickest time with a 1m:17.316 while Vettel was now fourth. Vettel would continue to find time with a 1m:17.309 to be fastest. With under ten minutes remaining Schumacher would crash at Ste Devote sliding sideways into the barrier after locking up and not making the escape road. Rosberg was now quickest with a 1m:17.139 while for Williams Pastor would move into seventh with a 1m:18.527.

As the final minutes counted own Vettel would return to the top of the times with a 1m:16.781. Alonso was second with a 1m:17.109. But right at the end of the session Alonso would set a 1m:16.732 to go fastest but Vettel would retake this spot with a 1m:16.619.
