Programme:
The track was wet in the morning; therefore the team began testing in the afternoon after it had dried out. Robert Kubica continued his work from yesterday and concentrated on further improving the mechanical set-up of the car, as well as fine-tuning the electronic systems. He then made a tyre comparison, also doing some long-runs. Despite the difficult weather conditions, the team was finally able to complete the programme in preparation for the Italian Grand Prix.
What comes next:
The BMW Sauber F1 Team will be testing again from September 18 to 20 in Jerez.
