Driver: Pastor Maldonado / Bruno SennaChassis / engine: FW34-02 / RS27-5341/1Location: Circuit de Catalunya, Barcelona 4.655kmObjectives: Pitstop practiceWeather: Dry and sunny all dayAmbient & track temps: 23ºC / 31ºC

Mark Gillan, Chief Operations Engineer: Today the team concentrated on practicing our pit stops, completing 68 mostly in- and out-laps to get  the drivers and pit crew used to the new equipment and procedures. Pastor's morning session was compromised with an engine-related problem which, although easy to rectify, took some time to identify. Bruno's running in the afternoon was trouble free.

Pastor Maldonado: Our focus today was on pitstop practice, which is important to do before we get into a live race situation. Getting a clean, fast pitstop involves a combination of factors from both the team and driver. From my side, I have to position the car correctly in the box, get a good pull away from the stop and make sure I have clean in- and out-laps. We are trying many different things to improve all of these areas.

Bruno Senna: This afternoon was great as we did a lot of practice to understand our pitstop performance as a team. It is very important to practice as you come in at 100kph, the speed you would do on a motorway, and jump into a space just the size of the car. There is a lot of time to be made, and races can be decided by pitstops. I think we’ve really improved our performance today. I’m now looking forward to doing some stops in a race, and to being quick and precise when the pressure is on.

The Williams F1 Team will be back on track today Saturday 3 March, with Bruno Senna driving the FW34 for the third day of the test.
