After three days of testing the team fairly confident of a positive result in the Spanish Grand Prix next weekend.

WilliamsF1 Chief Operations Engineer Sam Michael commented on the three days of testing: “Although we progressed through the test program at Silverstone this week it was hampered by Juan-Pablo’s crash yesterday afternoon and by bad weather today. However, we have still learnt a great deal and tested some new parts ready for the Spanish Grand Prix next week. Marc finished off the test today by verifying some wet and dry tyre choices for Michelin”.

BMW Motorsport Director Mario Theissen added: “The test has been focussed on specific set-up work for the Silverstone circuit as well as on intense tyre testing. With regards to the engine, we have been working on further improvements of the traction control as it is now assured that we will be allowed to use this feature for the entire 2003 season. For today, the final day of the Silverstone test, a race simulation had been scheduled but was hampered and interrupted by changing weather conditions and heavy rain”.
