Sauber has confirmed that technical director Jorg Zander has left the team with immediate effect. The news came on Wednesday afternoon, and just a number of weeks after the Swiss squad appointed a new head of aerodynamics.
Zander joined Sauber at the end of 2016 when Audi Sport departed from the World Endurance Championship. Zander worked as the German outfit's Head of Technology, before linking up with Sauber for the start of the 2017 season.
A statement from Sauber confirmed that Zander has now left the squad. Team principal Frederic Vasseur will overlook Sauber's development of the 2018 car and the initial plans for its 2019 challenger "until a new organisation" is confirmed.
Sauber is currently in the process of rebuilding and re-organising. This year, it forms a title sponsorship with Alfa Romeo as it hopes to make gains towards the midfield, after it has struggled for the last number of seasons.
