Back on track after the tremendous victory in Catalunya, Williams were back to work carrying out aerodynamic evaluations and the usual tyre and set up work on their FW34's. And luckily for Bruno Senna, he has been given the entire day to drive instead of switching with a reserve driver as seen in previous GP's.
• Aero evaluations
• Tyre runs and set-up work
Mark Gillan, Chief Operations Engineer: This morning we had a productive session with both drivers successfully working through their test programmes, but unfortunately the wet second session in the afternoon proved more problematic and limited useful running. Both drivers were happier with the car balance in the second session but we still have quite a bit more to do in preparation for Sunday.
Pastor Maldonado: The car is feeling really good this year and looks competitive in the running we have done today, so we’re happy with that. It's a shame we didn't get to run as much during the afternoon, as we would have liked to have gathered a bit more data on the tyres but we still have P3 on Saturday. I love this circuit and think it's going to be a competitive Grand Prix.
Bruno Senna: It was great to be able to do both sessions today as it meant that we could learn bit by bit. It's been quite a few years since I drove something competitive here so it was good to have extra time to remember the track. We’re chipping away and the afternoon session was hampered by the rain, but every little helps.
