Replaced by Sergio Pérez in 2021, Albon continued as a reserve driver for Red Bull and the re-branded AlphaTauri, contesting DTM with Red Bull AF Corse alongside Liam Lawson. Albon signed for Williams in 2022 to replace George Russell, ending his association with Red Bull at the conclusion of his first season.
