Joining Albers on their first visit to the circuit was Patrick Friesacher, Narain Karthikeyan, Tiago Monteiro and Red Bulls' Tonio Liuzzi.

For the BMW WilliamsF1 team the FW27 would be carrying several new parts as they aim to improve the cars performance. The practice session would see many drivers make their installation lap, including the likes of Montoya, Wurz, Klein. The first driver to set a time would be Wurz with a 1m:24.835.

With twenty minutes of the session run Liuzzi would set a time of 1m:23.305 to be second. Wurz was back out and would set a time of 1m:21.835 to push Liuzzi down one spot but the Italian would set a time to take the spot back.

At the front Wurz would go fastest with a 1m:20.244. Joining him would be the two Ferrari's of Michael Schumacher and Barrichello. Wurz would lower his time with a 1m:19.601.

Mark would move into seventh with a time of 1m:22.840, while Rubens was thirteenth and Ralf Schumacher fourth. But is a stunning piece of drving Michael Schumacher would go fastest with a time of 1m:19.522 after just one lap. But Kimi Raikkonen and Mark Webber would push him down the order as the McLaren and WilliansF1 drivers moved into first and second respectively.

Michael would return to the top of the times. Renault's Fernando Alonso would set a time of 1m:18.936 on his first lap. Toyota's Jarno Trulli, a previous winner, would set a time of 1m:23.957, good enough for only seventeenth. Klien would go fastest with a time of 1m:17.511.
