Bruno Senna
Williams promoted test and reserve driver Valtteri Bottas to a full-time racing seat alongside Pastor Maldonado, replacing Bruno Senna. Bottas, the 2011 GP3 Series champion, made regular appearances for Williams during the season, in official practice sessions at fifteen Grands Prix. Faced with the loss of his seat, Bruno Senna initially sought a drive with Force India, but instead moved to the World Endurance Championship, joining Aston Martin Racing.
