Sauber's head of track engineering Giampaolo Dall'Ara is set to leave the team and move to DTM, with Red Bull's Tim Malyon replacing him.
Dall'Ara has been at Sauber since 2000, initially joining as a test engineer before moving through the ranks to become head of track engineering in 2009 when the team was owned by BMW, retaining the role following the German manufacturer's departure from the sport at the end of that year.
While he became senior strategy engineer in 2013, Dall'Ara reverted to the title of head of track engineering for the past two seasons. The Italian is now set to leave Sauber to join BMW in DTM following 15 years in Formula One, with Malyon - who was most recently race engineer (car performance) at Red Bull - replacing him.
"Giampaolo Dall’Ara has decided to leave our company after more than 15 years of service to pursue another challenge," a Sauber spokesperson told F1i. "We would like to thank Giampaolo for his dedicated and highly valued collaboration over all these years. We wish him all the best for the future.
"At the same time, we are very pleased to announce Timothy Malyon as our new Head of Track Engineering. Tim has been working for more than ten years for one of the big F1 teams. We are confident that we can benefit from his longtime experience in order to improve our performance."
