For the AT&T Williams team the lead-up to today was encouraging with the Williams drivers finishing Friday with the fourth and seventh fastest times. Kazuki Nakajima was ahead of his team-mate Nico Rosberg so it would be interesting to see if Kazuki can continue this in the Saturday practice and qualifying. It would also be interesting to see if the Williams team can have a positive Saturday. First out in the session was Glock with Nico joining several other drivers out on the track. Kazuki would also come out for his installation lap with Raikkonen and Barrichello the only two yet to come out.

Trulli was second followed by Sutil and Glock. Massa would again improve with a 1m:29.046 while Trulli was down to a 1m:29.754.

Raikkonen was up to third, 1m:28.467, while Barrichello was up to fourth. Raikkonen would pit with just over fifteen minutes left in the session. Kazuki had dropped to ninth, 1m:28.645.

The drivers would again complete practice starts from the grid prior to returning to their pits.

Kazuki had again out performed his team-mate in this session. Will he repeat this in qualifying? Another solid performance from both Williams drivers in the lead-up to qualifying. Nico and Kazuki took different approaches to the session with Nico coming out early on the softer tyre to set his quickest time while Kazuki would wait until the final run late in the session.
