The Williams FW42 finally started testing on Wednesday after numerous delays with the team’s new car.
A filming day on Saturday took place without the car, before the team announced it would miss the first day of testing due to build delays. That extended into Tuesday but after the car arrived at the Circuit de Barcelona-Catalunya overnight it finally appeared on track in the 30 minutes after the lunch break on Wednesday.
George Russell was tasked with giving the car its first run and duly completed just one installation lap before Williams could carry out checks back in the garage. Further short runs took place later in the afternoon, with the team limited in the work it could do due to a number of parts still being delayed.
Those missing parts are expected to arrive on Wednesday evening, and deputy team principal Claire Williams said the team will be able to get down to its aerodynamic program on Thursday.
Robert Kubica will drive on Thursday morning before handing back to Russell, with reserve driver Nicholas Latifi giving up his planned time in the car this week so the team can focus on making up lost time.
