When George Russell and Nicholas Latifi leave the pits at the Red Bull Ring for free practice this Friday, their cars will look noticeably different from when a Williams FW43 last graced the track in Formula 1 winter testing.
Williams has adopted a new colour scheme after splitting with former title sponsor ROKiT at the end of May. Now the team's 2020 challenger is a sleek overall white with blue flashes, where once it was jarringly splashed with red.
The FW43 does now look very clean, but definitely a little bare - with 'Williams' writ large on the rear wing in place of a sponsor's logo a reminder of what the team has recently been through. Off-track developments over the past few months point to deeper change at Williams than merely new colours. Indeed, if certain suggestions play out, they could result in the biggest change in the family-run squad's 42-year history as an F1 constructor.
