Rosberg fastest on day one of Barcelona Test

The AT&T Williams team would return to the Circuit de Catalunya for a further three days of testing at the Spanish circuit. The last time the team had visited this circuit they had to abandon their test due to a failure with the front wing which could not be resolved at the track.

This time the team would return with a front wing with a new design for the front wing mounting points. Present for the days testing were race drivers Nico Rosberg and Kazuki Nakajima.

The day would see difficult weather conditions with cloud and intermittent rain affecting the circuit. Nico was able to make the most of the conditions and set the fastest time of the day with a 1m:30.675. Kazuki was second fastest but some 1.6 seconds slower than Nico.

Kazuki would complete ninety six laps compared to Nico's seventy three. Kazuki was focusing on shorter runs whereas Nico completed longer one's.

Williams F1 Test Team Manager Dickie Stanford commented: “The weather really hampered play today in Barcelona. The intermittent rain, in particular, made the track very greasy for the duration of the session. Rosberg and Nakajima were in the cockpit for us and concentrated on set-up work and endurance runs so our running wasn’t as adversely affected by the conditions as it perhaps was for others.”
