Williams Racing are one of the longest serving teams in Formula 1, and for the 2020 season they will take part using the FW43.
The livery is a complete overhaul of their 2019 design (see here), and is the first Williams car to feature a significant amount of red since the FW21 in 1999. The car is predominantly white, with red sidepods and blue lining around the nose towards the cockpit. It's grounded by black front and rear wing endplates with red and white sections.
The design also features an outline of primary sponsor ROKiT's icon in the red section, and with a dashed line treatment on the engine cover.
