At Silverstone Ralf would set the fastest time with a lap time of 1m:19.790, completing 123 laps. His time was way ahead of his rivals from teams such as Renault and Jordan. Ralf continue to focus on the set-up for the Canadian Grand Prix at Montreal.

For Marc his day was spent concentrating on setting up the chassis of the WilliamsF1 BMW FW25. Moreover he did some tyre testing for the race at Monza. Marc would have a minor technical problem but he would still finish the day with the fourth fastest time with a lap of 1m:22.976.

Sam Michael, WilliamsF1 Chief Operations Engineer, commented on the three days of testing by saying: "We finalised a busy programme at Silverstone today with extensive tyre testing and set-up work for Montreal, as well as engine endurance running for BMW. In all we managed to complete 640kms of useful work in a single day, and over the course of this test and our simultaneous programme at Monza, we have made some useful progress for Montreal and beyond."

Mario Theissen, BMW Motorsport Director, ADDED HIS THOUGHTS: "We have been testing at two different circuits this week. In Monza, the focus was on preparation work for Montreal, set-up work for the Italian Grand Prix and general tyre development. In Italy we were also working on the engine's set-up and development. During these tests we have been able to learn plenty from two defects which will assist with future development of the engine. The Silverstone test was mainly concerned with chassis development and set-up work for the British Grand Prix. In summary we have had two intensive and positive tests."
