Zsolt Baumgartner is first out, both Minardi drivers having sat-out the first session following the news that the team's sporting director John Walton, died late last night, following a massive heart attack on Tuesday morning.

The Australian posts the benchmark, crossing the line at 1:22.161, moments later, his Austrian teammate goes quicker with a 1:21.437.

Having completed only a couple of laps in the first session, Kimi Raikkonen is eager to get back on track, and proves that his earlier performance was no 'flash in the pan' by posting a 1:20.311 then a 1:19.752.

Meanwhile Alonso goes second and Fisichella fourth, as Panis slots into sixth place.

Raikkonen goes quickest in the first sector but then returns to the pits, as Alonso improves with a 1:20.685 and Fisichella improves to third.

Next time around he again goes quickest in the first sector, as Barrichello goes fourth with a 1:20.576. Unable to maintain the pace in the second sector (again), the German returns to his garage.

Raikkonen remains quickest, ahead of Alonso, Trulli, Coulthard, Barrichello, Schumacher, Button, Webber, Montoya and Gene.

With just over fifteen minutes remaining, we reach one of the lulls that we've come to expect during Saturday sessions, the proverbial 'calm before the storm'. The drivers have less than a quarter-of-an-hour to find the ideal set-up for qualifying.

Felipe Massa is the only driver that hasn't posted a time in this session, he finally exits the Sauber garage. There are only a few drivers on track - da Matta, Webber, Heidfeld, Gene, Pantano and Massa. The Brazilian goes ninth with a 1:20.285.

From (seemingly) out of nowhere, Gene produces a 1:18.832, to go second.

Meanwhile, Webber has completed the most laps (20), but remains twelfth.

The WilliamsF1s appear to have found some pace, Montoya goes third with a 1:18.912.

As Coulthard appears to begin what looks like a fast lap, Gianmaria Bruni stops in the first sector, bringing out the yellow flags.

Schumacher is back on track and immediately goes quickest in the first sector, but loses a heap of time in the second. He's got a couple more laps in which to improve.
