The session would see some light showers but these would not disrupt the days testing.

Ralf Schumacher would continue to show the from that has seen him winning the last two Grand Prix by setting the fastest time of the day. He would complete ninety seven laps altogether without any problems. Ralf carried out setup work and tyre testing.

Marc Gené also was able to work through his test program, finishing second after completing eighty nine laps. In the morning Marc focused on testing aerodynamic components, while in the afternoon he would concentrate on tyre evaluation tests.

Both Ralf and Marc were able to set times well ahead of those of Ferrari and McLaren.

WilliamsF1 Test Team Manager, Tim Newton: “It is only two days until the impending test ban takes effect and we have plenty to get through, but today was productive. Ralf and Marc completed useful mileage and maintained station at the top of the time sheets.

There has been a high pressure system over Spain for some time, and today we had a typical high temperature, high humidity outlook but thankfully it only rained once briefly this afternoon and our progress was not impeded.“
