Driver: Alex Lynn
Chassis / Engine: FW38-01 / PU106C Hybrid
Location: Silverstone Circuit, 5.891km
Weather: Cold and dry in the morning, rain in the afternoon
Maximum air & track temps: 20ºC / 17ºC
Rod 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.
Alex Lynn: 1.34.433 (3rd) on lap 24/54.
Quickest time: F. Alonso, 1:31.290 on lap 32/105.
The Williams Mercedes FW38 will be back on track tomorrow for day two of the test with Valtteri Bottas at the wheel.
