Red Bull Racing chief mechanic Matt Caller will depart the team at season's end to join Audi's Formula 1 program ahead of the manufacturer's 2026 entry into the championship. The move follows Audi's recent hiring of Ferrari engineers Wolf Zimmermann and Lars Schmidt, and both work under former Ferrari team principal Mattia Binotto, who serves as Audi's chief operating officer and chief technical officer. Audi will assume control of the Sauber team for its debut season under new team principal Jonathan Wheatley, who previously worked at Red Bull.
Caller joined Red Bull in June 2015 as a number two mechanic before earning promotion to chief mechanic in 2022. The veteran technician will assume a senior position at Audi, but the German manufacturer has not disclosed specific details about his new role. Caller's twin brother Jon remains at Red Bull as chief mechanic for driver Yuki Tsunoda, and the siblings will compete against each other when Audi enters the grid.
