The AT&T Williams team had another packed day of pre-season testing in southern Spain today. Nico Rosberg was once again on duty for the team at Jerez as the Williams-Toyota FW31 was put through its paces for the forthcoming season.
In a field of eight other teams, Nico posted a 1:21.412 and clocked up 125 laps of the 4.423km track.
Sam Michael, Technical Director, Williams F1:
"Nico had his last day in the car this week and concluded his run with set-up work for the majority of the day. He then carried out some aero and mechanical tests. It was quite wet on track this morning but it then dried out for the afternoon session which allowed us to get some good track time in. Kazuki will take over tomorrow."
