Williams: The car ran faultlessly

Williams report from day one of the second Formula 1 preseason test at Circuit de Barcelona-Catalunya in Spain.

Rod Nelson, Chief Test & Support Engineer: "Today was a very good day for us. The car ran faultlessly. We did lots of quite significant tests throughout the day as well as a bit of a qualifying simulation. We managed to get through our planned programme without any major problems, so overall we are really pleased."

Valtteri Bottas: "It was a good day today. We managed to run without any major issues with the car. It was very interesting discovering more about the FW38 and what kind of set-ups work for this car. I think we managed to make progress. We did some short runs today which I really enjoyed. I still agree with what I said last week – we have improved in the areas where we were weak last year. I am looking forward to tomorrow and continuing testing."
