As a result of heavy overnight rain, the track was damp when the session got underway. However, by mid-morning the track had dried, with temperatures gradually climbing to 17 degrees C.

Since this is the first time that the Williams BMW FW27 has run at Jerez, both drivers spent the day concentrating on set-ups.

Mark completed 78 laps on his way to posting a best time of 1:18.922, while Nick completed 99 laps with a best time of 1:18.743.

Tim Newton (Test Team Manager, WilliamsF1): ï¿½Mark and Nick were on testing duty today at Jerez, our first visit here with the FW27. We experienced a minor technical problem on Markï¿½s car early on in the session which we soon rectified, allowing Mark to continue his dayï¿½s programme of tyre testing and fuel system checks. Nick, meanwhile, was in a new car today so spent the session completing set-up work. Both drivers will continue testing tomorrow.ï¿½
