Sauber have parted ways with Technical Director Jorg Zander with immediate effect, just four races into the 2018 Formula 1 season…

Zander only joined the Swiss team ahead of the 2017 campaign from Audi as Sauber carried out a restructure of the outfit following the arrival of new owners the previous summer.

He and his team overhauled the design concept of the 2018 challenger, the C37, and it has shown promise, with Sauber scoring points in two of the first four races.

But on Tuesday, Sauber announced Zander, who was chief designer for BMW Sauber between 2006 and 2007, “will stop working for the team with immediate effect”.

The team added: “Various heads of departments and the current project leaders will continue to work on the development of the C37 and the 2019 car with the supervision of [Team Principal] Frederic Vasseur.

"We would like to thank him for his dedication and we wish Jorg Zander all the best and success for the future."
