At Jerez we would see Juan Pablo Montoya and at Imola Marc Gene, with both drivers continuing to work on the further development of the new FW25 and it systems. With only one week available for testing ahead of the season's opening race in Australian the need for this development is becoming even more urgent .

At Jerez Juan Pablo would complete sixty four laps while testing several tyre mixtures and specifications, different chassis settings as well as different aerodynamic features. His fastest time of the day would be a time of 1m:28.537, which was behind the fastest time of the day set by Michael Schumacher.

At the Imola circuit Marc would use a modified FW24. The Spaniard focused on extensive tyre tests and ended the day as the second fastest driver, setting a 1m:24.343. BAR driver Jacques Villeneuve, testing in his BAR005, was faster than Gené.

For Imola WilliamsF1 Test Team manager Tim Newton had the following comments: "The weather has been kinder to us here in Italy than our other test team in Jerez! Here we have been able to carry out some good work with Marc driving a development of last year's FW24. Despite the rain Juan Pablo has managed a decent number of laps in Spain however, which will also have produced some good data for us"
