Driver: Alex Lynn Chassis / Engine: FW38-01 / PU106C HybridLocation: Silverstone Circuit, 5.891kmWeather: Cold and dry in the morning, rain in the afternoonMaximum air & track temps: 20ºC / 17ºCRod Nelson, Chief Test & Support Engineer:Our running was affected by rain this afternoon, which is a shame because it limited the work we could complete today. We did some pretty reasonable testing this morning though, looking at mechanical set-ups, aerodynamic work and testing some new components on the car, and that’s something we’ll be looking to push forward with tomorrow when Valtteri is in the car and we expect better weather.Alex Lynn:I think we had a really productive morning. We got a lot done, collected a lot of interesting data for the team and completed many laps on the medium compound tyre. It was a shame I didn’t get to try out the soft tyre because the car felt really nice in the high-speed sections on the mediums. It was a bit of a shame that it was such a wet afternoon as well, but it is what it is with Silverstone playing its usual part. So aside from the weather setbacks in the afternoon, it was a good day.

Williams Martini Racing will be back on track tomorrow with Valtteri Bottas at the wheel of the Williams Mercedes FW38.
