Owned by the Williams family since its creation in 1972, the Williams F1 team changed owners in the fall of 2020, with the purchase from Dorliton Capital and the injection of US capital. Team manager is now Jost Capito, who has experience in the VW group. The FW43B for 2021 now adopts the Mercedes gearbox and has been completely redesigned in terms of aerodynamics and flat bottom. The engine is the Mercedes M12 EQ Power. The Williams driver duo does not change: high hopes are placed in George Russell, who has shown a lot of potential by replacing Hamilton at the 2020 Sakhir GP. The other driver, Latifi, who ensures part of the team's budget, showed promise in 2020 and seems to have a good margin for improvement.
