Guenther Steiner was one of F1's longest-serving Team Principals currently in post before his shock exit from Haas.
The American-owned outfit has opted to change direction and instead promote Ayao Komatsu to the post to place greater focus on optimising the squad's engineering potential.
The departure means that the entire grid's Team Principals' total longevity can't surpass Christian Horner's tenure in charge at Red Bull, an incredible feat underlining just how perfect the two parties are for each other.
Ahead of the start of car-launch season and the 2024 F1 World Championship, take a look at the table below to see how long each Team Principal has held their posts.
