Driver: Felipe MassaChassis / Engine: FW37-01 / PU106B HybridLocation: Circuit de Barcelona-Catalunya, 4.655kmObjectives: Aero and chassis workWeather: Hot and Dry Air & track temps: 19 - 31 ºC / 26 - 52 ºC

Rod Nelson, Chief Test & Support Engineer:  We had a good day with development work on this and next years’ cars. The conditions are similar to the weekend so we had the chance to get straight on with our programme. We completed everything we had planned and made good progress with the focus on tyre degradation. We have had no issues throughout the day which has given us a lot of data to get through tonight whilst we prepare the car for Alex tomorrow.

Felipe Massa: It has been a productive day and we got through the programme without any issues. In the morning we looked at aero work so I had a lot of equipment attached to the car. We then looked at set-up work in the afternoon. We had data from the weekend to start off with as a base and could move forward from there. There was a little less wind today than the last few days hence why lap times are a bit quicker. I will now turn my focus to Monaco which I am really looking forward to.
