Frederic Vasseur is to become Ferrari's new team principal in January after the departure of Mattia Binotto, the team announced on Tuesday.
Vasseur's newly vacant role as Alfa Romeo/Sauber's managing director is then expected to be filled by McLaren boss Andreas Seidl, ahead of Sauber's switch to becoming the Audi factory team in 2026.
Having been with Sauber in the team's various forms since 2017, Vasseur will join a Ferrari outfit that won four races in the 2022 season but remained well off the pace in challenging Red Bull and Max Verstappen for the constructors' and drivers' championships.
Ferrari announced in November that Binotto would step down at the end of the year, allowing Vasseur to join and reunite with Charles Leclerc.
He was in charge of Alfa Romeo during Leclerc's rookie F1 season in 2018.
Vasseur will be aiming to end Ferrari's long title drought, having not won a constructors' or drivers' championship since 2008.
Ferrari are still among the most prestigious and successful Formula One teams despite their long wait for more silverware, and Vasseur is thrilled to be joining such a historic constructor.
"I am truly delighted and honoured to take over the leadership of Scuderia Ferrari as Team Principal," Vasseur said in Ferrari's announcement.
"As someone who has always held a lifelong passion for motorsport, Ferrari has always represented the very pinnacle of the racing world to me."
Benedetto Vigna, Ferrari's CEO, added: "We are delighted to welcome Fred Vasseur to Ferrari as our Team Principal.
"Throughout his career he has successfully combined his technical strengths as a trained engineer with a consistent ability to bring out the best in his drivers and teams.
"This approach and his leadership are what we need to push Ferrari forward with renewed energy."
Vasseur's move comes in the wake of Jost Capito leaving his role as Williams team principal, having finished bottom of the 2022 constructors' standings.
