SPIELBERG, Austria -- After his latest session behind the wheel for Williams Robert Kubica joked that the strongest feature of the team's problematic FW41 is its livery.
Austria was the latest in Kubica's scheduled appearances in a race weekend's opening practice session. The Pole, who is Williams' reserve driver for 2018, replaced rookie Sergey Sirotkin on Friday morning and completed 38 laps.
Williams has struggled for pace this year and had a car at the bottom of the order in both Friday sessions -- Kubica in FP1 and Lance Stroll in FP2.
In his Friday session which followed FP1, Kubica was asked what he felt was the car's strongest trait.
