Paddy Lowe, Chief Technical Officer: We had the best weather so far of this pre-season testing period with clear skies, and it was relatively warm without significant wind. We had a bit of a slow start with a small issue on the car which unfortunately took an hour to understand, but then Lance achieved a very good set of runs, running sets of new softs doing performance tests, and that took us to lunchtime. We managed a lot of work very quickly at lunchtime to get out just after two o’clock with Sergey doing extensive work on soft tyres at high fuel. The afternoon was interrupted by an electrical issue which again, lost us about an hour, but we continued that work into a race simulation, including the hypersoft tyre as we did yesterday. We ended the day with the FIA restart sequence tests. We managed a very decent lap count although it would have been far higher if we hadn’t lost an hour in the morning and an hour in the afternoon.
Lance Stroll: There is not an awful lot to say about today except, like yesterday, it has been another good day. I was just in the car this morning, got plenty of running and felt good in the car. We have certainly made another step, so now it is just a matter of continuing that good rhythm and seeing where we are at the end of the week.
Sergey Sirotkin: We had a good day in total, despite a couple of small issues. We covered a lot of laps during the afternoon, including my first race simulation, so that felt good. We boxed for a small problem but we managed to sort it quite quickly, so overall, I think we can be happy with how today went.
The FW41 returns to the track tomorrow with Robert driving in the morning session, before handing over to Lance in the afternoon.
