At the end of the day it would be Juan Pablo would would set the fastest time as the team works towards further understanding the new FW26. It was not a day for really quick times, as indicated by the fact that Juan Pablo's time was over a second slower than the track record set by BAR's Takuma Sato.

Juan Pablo would set a time of 1m:14.804, completing fifty one laps as he worked through a programme of tyre testing evaluating various tyre compounds and constructions.

For Antonio Pizzonia he would spend his day conducting system checks while he familiarised himself with the new FW26. He would set a best lap time of 1m:15.112, completing fifty one laps. For Nelsinho Piquet it was again a case of coming to grips with a F1 car and a totally new circuit. He would use last years FW25, setting a best lap time of 1m:15.809.

WilliamsF1 Chief Operations Engineer Sam Michael said: "Antonio Pizzonia and Nelson Piquet picked up testing responsibilities alongside Juan Pablo today. Antonio concentrated on running systems checks today, while Juan focused on tyre testing. We had some interruptions but across the day managed a useful 700km or so. Nelson Piquet joined the programme today in an FW25 and made a good contribution.”

Juan Pablo and Antonio will be returning tomorrow for the last day of testing.
