Sauber has confirmed Frédéric Vasseur as its new Team Principal, with his position at the squad effective on Monday.
Vasseur, who heads up the ART outfit in junior categories, spent 2016 as Racing Director, latterly Team Principal, at Renault, but left the manufacturer during the winter break, due to differences over the direction of the team.
Sauber, meanwhile, was left without a Team Principal in the wake of Monisha Kaltenborn's exit, prior to the Azerbaijan Grand Prix.
Vasseur has now filled that role, and will take up his new position following this weekend's British Grand Prix.
"I’m very proud to be joining Sauber Motorsport AG, and wish to thank the company’s shareholders for their trust in me," said Vasseur.
"I’ve been impressed by the facilities in Hinwil and by the talent and ambition of the workforce, and I very much look forward to complementing the team with my experience and determination and drive all people in the right direction in everything they do: I am convinced that all together we will achieve ambitious targets.
"I cannot wait to start working with our drivers, engineers and all the staff. I look forward to contributing to the next important phase in the development of the team."
