Mark Gillan, Chief Operations Engineer: We had another good test day to end what has been a very productive pre-season test programme. We successfully ran the first race update package this morning with Bruno, and switched drivers to Pastor over the lunch break. The wind picked up throughout the day, making the afternoon conditions a lot trickier than those encountered in the morning. Over the last three tests we have completed all of our primary testing objectives and now eagerly turn our attentions towards the back-to-back opening races in Australia and Malaysia.

Bruno Senna: We had a productive morning completing a number of tyre tests and aero runs. It has been interesting to see the car developing. Overall we've had a good few days of running here in Barcelona. We are still improving, but I feel we are in a solid position to go to Australia.

Pastor Maldonado: We completed some good runs this afternoon and ended our test programme without issue. I'm feeling positive, and ready for Australia.

The Williams F1 Team will be back on track in Melbourne for the Australian Grand Prix, 16 - 18 March
