As part of the commemorative livery, the engine cover of the Williams FW45 driven by Alex Albon and Logan Sargeant has been draped in the Union Jack. The Grove-based team’s 800-race landmark is also referenced on the sidepods.
Its sponsor Gulf has received more prominent branding on the car's rear wing endplates.
The Silverstone weekend was set to be Williams' 800th grand prix, but due to the cancellation of Imola's Emilia Romagna Grand Prix, that landmark had inconveniently shifted from the squad's home race to the following round in Hungary.
Williams has decided to keep the livery on the car for both race weekends so it can still celebrate its anniversary in front of its British fans in Silverstone.
According to the team, the livery "pays homage to the team's British heritage and to its beloved founder, the late Sir Frank Williams."
Williams, who died in November 2021, was at the helm of the team for most of its 800 races, overseeing nine constructors' championships and seven drivers' championships between 1977 and 2020.
