Nico Rosberg was back on track today for day three of the four day opening test of the year at the Autodromo do Algarve. After two days of severely disrupted running due to torrential rain in Portimao, the teams enjoyed a much drier day today as only the first couple of hours of this morning's session were disrupted by rain showers.

Of the drivers running 2009 cars this week, Nico was the quickest of the field today with a 1:29.729 and completed an impressive 143 laps of the 4.686km Portuguese track.

Sam Michael, Technical Director, Williams F1: “We had a wet track for the first couple of hours in Portimao today, but by late morning it had dried out enabling us to run slick tyres on the FW31 for the first time. It was a constructive day as we worked through a lot of the items on our job list, including systems checks, aerodynamic and mechanical performance tests. The FW31 reliably completed just over 670kms today on only its third day on track. Kazuki will take over from Nico for the last day of testing tomorrow and for his first run in the new car.”
