Driver Rubens BarrichelloChassis / engine FW33-01 / CA320Location Circuito de la Comunidad Valenciana Ricardo Tormo. 4.005kmObjectives Initial systems, performance and reliability checks with the FW33Weather Cold with some cloud in the morning, bright in the afternoonAir & track temps 18ºC / 20ºC

Sam Michael, Technical Director: It’s been a good day in terms of getting through things. We had a problem with KERS this morning so we didn’t use it in the afternoon. Besides that, everything else on the car is working and we didn’t have any problems with temperatures, pressures and all the systems are working fine. We now plan to do more mileage and setup work tomorrow. The moveable rear wing also worked fine today so all in all a pretty good first day.

Rubens Barrichello: I couldn’t wait to get back in the car. Unfortunately we lost a lot of time in the morning so we were trying to play catch up in the afternoon. We did some good laps and some long runs in the car. It is too early to say how we are performing but we will now spend time to try and understand the car a little better.

AT&T Williams will be back on track tomorrow, Wednesday 2 February, with Rubens Barrichello driving in the morning session and Pastor Maldonado driving the afternoon session for the second day of the test.

Photography from this week’s running will be available at the end of each day.
