Williams: Interesting day working with different set-ups 21 February, 2012 Bruno Senna Feb.21 (Williams) Team and driver report on day one of Formula 1 testing from Circuit de Catalunya in Barcelona. Mark Gillan, Chief Operations Engineer: “Bruno was on track today as we began the penultimate test before heading off to the first race of the season. We completed 97 laps around Barcelona’s Circuit de Catalunya, working successfully through a detailed aero correlation test programme in the morning before moving on to car set-up optimisation, utilising a range of tyre compounds throughout the afternoon. We continue tomorrow with Valtteri in the FW34 before Pastor takes over for the final two days.” Bruno Senna: “It has been a very interesting day working with different set-ups to assess the reliability of the FW34. We need to keep working hard to understand the car even better. The team will continue working over the next few days with Valtteri and Pastor, as we look to improve both pace and consistency.” The Williams F1 Team will be back on track tomorrow, Wednesday 22 February, with Valtteri Bottas driving the FW34 for the second day of the test.
