Driver: Valtteri BottasChassis / Engine: FW38-02 / PU106C HybridLocation: Circuit de Barcelona-Catalunya, 4.655kmWeather: Warm and DryMaximum air & track temps: 20ºC / 27ºCRod Nelson, Chief Test & Support Engineer:It has been quite a positive day for us. We were aiming for some longer runs and reliability work. We also did some aero work and quite a lot of chassis work. It has been an interesting day for all the engineers and the driver. I am looking forward to Felipe getting in the car for the first time tomorrow to get a different point of view. We are all working hard and it has been a good day. Valtteri Bottas:We completed the whole programme we had for today, so that is always good. Everyone in the garage has been working very hard. I am pleased with the amount of laps we did today, with the mileage and reliability that we already have in the car. Like yesterday, we are just going through our programme and not focussing on the performance yet, so there is still a question mark as to where we are compared to the other teams. I think it will be interesting to follow what things Felipe is going to try with the car. I’m looking forward to next week now as well, to get back in the car and try to get a bit more out of it.

Williams Martini Racing will be back on track tomorrow with Felipe Massa at the wheel of the Williams Mercedes FW38 for day three of the test.
