Nico Rosberg took over testing duties from Nico Hulkenberg at a sunny Jerez today. Concentrating on set-up work on the FW31 before Melbourne, Nico covered the most mileage of the five drivers on track today, clocking 123 laps of the 4.423km circuit while setting the fifth fastest time of the session with a 1:19.783.
Nico will return to the cockpit for his final day of testing tomorrow before Kazuki Nakajima takes over.
Dickie Stanford, Test Team Manager, Williams F1: "Nico Rosberg is having his final two days of testing in the car this week before the first race in Australia. We completed a very full programme, with the majority of laps spent on set-up work. Nico will carry on testing tomorrow."
