Kimi Raikkonen would come away from the 3rd practice session with the fastest time. Now, as the teams prepared for qualifying, he would have one more practice session to stamp his authority on proceedings. After having missed the first Saturday practice it was not surprising to see Minardi's Zsolt Baumgartner and Gianmaria Bruni be first out in the session. Next out were the Jaguar's of Mark Webber and Christian Klien. A 1m:21.161 for Webber while Klein would go slightly slower with a 1:21.437.

Kimi Raikkonen was out early and would easily move to the top of the times with a 1m:20.311. He would quickly improve his time with a 1:19.752. Renault's Fernando Alonso would go second with a 1m:20.881, while Sauber's Giancarlo Fisichella moves into third. Raikkonen would pit.

McLaren team-mate David Coulthard would set a time of 1m:22.942 on his first lap, finishing in seventh. Renault's Jarno Trulli would move into fifth with a 1m:21.460. BAR's Jenson Button was now in fourth with a 1m:21.255. Both Button and Trulli would improve their times to move into third and fourth respectively.

Michael Schumacher would finish his lap in second with a 1m:19.929. With fifteen minutes of the session run Michael would return to his pit while team-mate Barrichello would move into third with a 1m:20.012. Even with Raikkonen's pace both Ferrari's were looking strong. For WilliamsF1 Marc Gene was in seventh with a 1m:20.748.

Showing that McLaren still to contend with Ferrari Rubens would set a time of 1:19.484 to go fastest. Juan Pablo would move up to seventh with a time of 1m:20.724, pushing Marc down one place. In a continuation of his good form in France Fernando Alonso would go fastest with a time of 1m:19.169.

With twenty minutes left all the teams were getting ready for this afternoon's qualifying. Joining the drivers who had gone fastest was Jarno Trulli who would go fastest with a time of 1m:19.171. But this would not last long as Raikkonen would drop his times into the 1m:18 second bracket with a time of 1m:18.280 to go back on top of the times.

Michael Schumacher was back out on the track but in his effort to set a quick time he would go off the track seeing him with a walk back to the pits. But one of the favourite teams to find the going difficult was BAR with Takuma Sato only in tenth with a 1m:20.837. Juan Pablo would suddenly find some extra speed and his times would move into the 1:18 seconds with a 1m:18.912 to be second.

Felipe Massa would set a time of 1m:20.285 to be ninth. Joining Juan Pablo at the front a time of 1m:18.832 from Marc Gene would see him move into second pushing his team-mate in third. Everyone was pushing hard to see how they would go in qualifying. With eight minutes remaining in the session the next driver to set a quick time would be BAR's Jenson Button who would set a time of 1m:18.414 to now be in second. This was a surprise as they seemed to be struggling. Trulli would go third with a 1m:18.694.

Rubens Barrichello would go fastest through the first sector with a 24.8 but in sector two he would lose time to Kimi. A 1m:18.623 would see him in third. Team-mate Michael Schumacher was back on the track after his earlier problems. He would set a time of 1m:18.951 to be down in eighth.

So with the end of the session Marc and Juan Pablo would finish in fifth and sixth, with a test driver, like Anthony Davidson for BAR, again their good form. Qualifying will be difficult for the WilliamsF1 drivers as they have not been near the top of the times.
