SATURDAY 3 MARCH, 2012

Driver: Bruno SennaChassis / engine: FW34-02 / RS27-5281/1Location: Circuit de Catalunya, Barcelona 4.655kmObjectives: Aero tests and race simulationWeather: Dry and sunny in the morning, cloudy with some rain in the afternoonAmbient & track temps: 19ºC / 23ºC

Mark Gillan, Chief Operations Engineer: We had a productive day's testing today, with Bruno completing 111 laps without issue. We concentrated on aerodynamic testing this morning prior to moving onto a race simulation. At the end of the race simulation, it started to rain and we reverted from dry tyres on to intermediates.

Bruno Senna: Today was a very good day. We completed some runs on lower fuel, which I hadn’t done before, using all the different tyre compounds. I was then able to do a full race simulation this afternoon, to learn more about the car and tyres in a race situation. We have a lot of valuable information to look at now, which will enable us to improve for next time. Unfortunately we had to cut our race simulation a bit short due to the rain, however we still met all our objectives for the day.

The Williams F1 Team will be back on track tomorrow, Sunday 4 March, with Bruno Senna driving in the morning session and Pastor Maldonado driving the afternoon session for the final day of pre-season testing.
