Andreas Seidl has been removed as head of Audi's Formula 1 project and replaced by former Ferrari team boss Mattia Binotto.
The decision to replace Seidl, after 19 months in the role of chief executive officer, comes amid concerns about the progress of the Sauber team that Audi has taken over as the basis for its F1 entry in 2026.
Oliver Hoffmann, previously chairman of the boards of all Sauber companies, has also been removed from his role.
Binotto, who was replaced as Ferrari team principal after the 2022 season, has taken on the role of chief operating and chief technical officer.
Gernot Döllner, who has been appointed the new chairman of the boards of Sauber companies, said: "With his extensive experience of more than 25 years in F1, [Binotto] will undoubtedly be able to make a decisive contribution for Audi.
"Our aim is to bring the entire F1 project up to F1 speed by means of clear management structures, defined responsibilities, reduced interfaces, and efficient decision-making processes.
"For this purpose, the team must be able to act independently and quickly."
Seidl started in his role for Audi in January last year, after four years with McLaren.
