For the BMW WilliamsF1 team the second Friday practice session at Silverstone would see the day end with a similar result to that achieved in France. Both drivers would be down the order with Mark and Nick finishing the session in twelfth and eighteenth positions. Based on the teams performance in France, and even taking into account the fact that the team does tend to run slower on the Friday, the times that both drivers were able to achieve may be something that they can not improve upon.

The practice session would see several drivers quickly setting times with de la
Rosa fastest with a 1m:23.129. In second was Red Bull's Vitantonio Liuzzi with a time of 1m:24.705, followed by Toyota's Ricardo Zonta in third with a 1m:25.129. Renault's Fernando Alonso would make his first appearance and his first lap would see him set a time of 1m:23.336.

He would improve on his time with a 1m:22.060 to go fastest. Joining Alonso would be McLaren's Juan Pablo Montoya.

Michael Schumacher was out and he would set a time of 1m:21.569 which would see him in third. Montoya would set a time of 1m:21.364 to be in second while de la Rosa would again secure the fastest time but Michael would move ahead of the Spaniard with a time of 1m:21.261.
