With the AT&T Williams team finishing Friday practice in first and second, with Nico Rosberg leading Kazuki Nakajima, Saturday practice would give the Williams team a further opportunity to assess their performance. Most teams had found the softer Bridgestone tyre durable in the conditions while the harder tyre was more difficult to get grip from. It would be interesting to see what strategies the Williams team would come up with. The session would get underway with the drivers, including Nico and Kazuki, completing their installation lap.

Everyone would complete their lap and with ten minutes of the session complete it would be Glock who would set the first lap time, a 1m:25.987. Glock would improve with a 1m:24.640. Team-mate Trulli was also out on the track and would go fastest with a 1m:24.512. Glock would lower his time by a fraction with a 1m:24.635. Kubica would move from third to first with a time of 1m:23.741. Team-mate Heidfeld was now second while Alonso would move to the top of the times with a 1m:23.261. Alonso was on the harder tyre. Both Nico and Kazuki were also out on the track as Raikkonen, on the harder tyre, moved into fourth. Alonso would improve his time with a 1m:23.074.

As the track became busier it would be Massa who would move to the top of the times with a 1m:22.387. Team-mate Raikkonen would move up to second pushing Buemi to third. Kazuki, 1m:23.263, was in eighth while Nico, 1m:23.352, was in ninth. Both Ferrari's would pit briefly with just over thirty minutes left in the session. Barrichello was in fourth followed by Vettel, Hamilton, Bourdais, Alonso, Kazuki, and in tenth Nico. Fisichella had spun his Force India between Turn seven and eight but was able to continue. Both Williams drivers would pit joined by most of the field as we had Heidfeld crash his BMW heavily at Turn twelve. He was able to get out of his car but it was badly damaged in the front left corner.

After his car was removed drivers would return to the track. Nico was back out while Alonso continued on the harder tyre. Nico was currently in twelfth and Kazuki tenth. Nico would improve one place to be eleventh, 1m:23.294. At the front Barrichello would split the Ferrari's moving into second with a 1m:22.483. Buemi was now third with a 1m:22.565. Barrichello was now fastest with a 1m:21.906 while Vettel moved into second. Raikkonen would move ahead of Vettel with a 1m:21.928. Massa would join Kimi at the top setting the fastest time with a 1m:21.547, running on the harder tyre.

Some drivers would start their soft tyre runs with Bourdais moving up to fifth from tenth. Fisichella was sixth while Bourdais improved with a 1m:22.044 but remained fifth. Glock would move to the top of the times with a 1m:21.419 using the soft tyre. Raikkonen was able to move to fifth using the harder tyre. Nico would make a mistake at the Campsa corner running wide onto the access road. He was able to continue as Glock lowered his time with a 1m:21.377. Button was now second with a 1m:21.466. Button's time was on the harder tyre. Massa was now third followed by Hamilton, using the softer tyre, Raikkonen, Webber, Kovalainen, Barrichello, Piquet, and Vettel in tenth.

Kazuki was now thirteenth while Nico had dropped way down the order to be seventeenth. With the final six minutes counting down the drivers would return to the track for their final practice qualifying runs. Both Kazuki and Nico had returned to the track. Everyone was back out on what was now a very busy track. Massa would return to the top of the times on a soft tyre run, 1m:20.533. Raikkonen would join on in second with a 1m:20.635. Button was now third followed by Barrichello. Raikkonen would improve with a 1m:20.635 to be just behind Massa. Kubica would move up to fifth followed by Trulli, Hamilton, and Glock in eighth. Buemi had been able to move from fifteenth to ninth.

Nico would finish the session in twelfth while Kazuki was down the order in eighteenth with a 1m:22.043. Nico's time was a 1m:21.594. Both Nico and Kazuki had struggled with traffic as they tried to set a better time. Neither driver was able to better their Friday times. Based on their Friday results this was not the result that the Williams team had hoped for as they prepare for qualifying.
