Yasuhisa Arai will step down from his role as Honda's Formula 1 boss next week, having been moved to a different role within the Japanese corporation.
Arai has been Honda's motorsport boss since the manufacturer returned to Formula 1 as engine supplier to McLaren, though the partnership endured a troublesome 2015 and placed only ninth in the standings.
Effective March 1, Arai will be replaced by Yusuke Hasegawa while a new role has been created to oversee the entire project, with Honda confirming Yoshiyuki Matsumoto as a Supervising Director.
Matsumoto will take up his position at the start of April.
Arai has been moved to a new role as Senior Managing Officer, Honda R&D, which he will take up next Tuesday.
The Honda-powered McLaren MP4-31 made its track debut during testing on Monday.
