The final day of testing for the Williams Martini team would again see Felipe Massa take to the track. This first run would see Felipe run past the pits slowly conducting aero testing with constant speed runs. His slow pace was shown in his lap time a slow 1m:50.918. He would improve but again the lap time was slow, 1m:49.531. Felipe was running on unmarked Pirelli tyres. Felipe would pit having completed eleven laps. Quickest at this time was Magnussen with a 1m:25.263 followed by Raikkonen.

Felipe would continue his aero work and would set a 1m:38.216, not that meant anything. Two hours completed and Felipe had only finished nineteen laps. Another run from Felipe and he would continue to add to his laps. He would pit again having completed twenty eight laps. The final hour of the morning session would see Felipe still in his pit. Raikkonen will go fastest with a 1m:24.460, running on the soft tyre. Felipe was back out running on the medium tyre and would move up to eighth with a time of 1m:28.684. With the lunch time break Felipe had completed thirty three laps. At the front Raikkonen had improved on the quickest time using the ultrasoft tyre setting a 1m:23.477, while Magnussen was second.

With the lunch break over it would be a considerable amount of time before the FW38 returned to the track. He would improve with a 1m:26.942 on one run but he would pit and would return running on the soft tyres to set a 1m:26.483. He would again pit returning on medium tyres where he would lap in the 1m:27s. With a red flag he would be forced to pit but would returning quickly to complete the afternoon session.

Williams Martini Racing return to track on Tuesday 1st March for the second test in Barcelona, with Valtteri Bottas at the wheel of the FW38.

Rod Nelson, Chief Test & Support Engineer:
Today was one of those days I’m afraid. We spent most of the morning doing aerodynamic correlation work which was pretty successful. We are getting through our programme day by day. Sadly, we had an issue with one of the car systems over lunchtime and that curtailed a lot of our running this afternoon which we had planned. We know what the issue is, we’ve got a solution, and now we look forward to next week.

Felipe Massa:
I am not so happy with today - it was not really a useful day. The most important things was that we carried out our aerodynamic tests this morning, to understand the numbers and everything around the car. Unfortunately, we couldn’t run much this afternoon. I had hoped to do more laps than I did.
