F1 team principal shake-up: Fred Vasseur becomes second longest-serving after Christian Horner’s exit. Frederic Vasseur and Andrea Stella are now the second and third longest-serving F1 team principals.

In the fast-paced and ever-changing world of Formula 1, stability is becoming increasingly rare—especially at the top of the team structures. Following the shock dismissal of Christian Horner from his role as Team Principal of Red Bull Racing, the sport is witnessing a significant shift in the landscape of leadership. With Horner now out, Frederic Vasseur of Scuderia Ferrari and Andrea Stella of McLaren Racing have suddenly found themselves among the most senior figures on the pit wall.

Christian Horner’s departure marks the end of an era

Twenty years of leadership came to an abrupt end in just one morning. Christian Horner, who had led Red Bull Racing since its inception in 2005, is no longer at the helm after being dismissed by the team’s management in Milton Keynes. The decision reportedly came from the upper ranks of Red Bull GmbH, in particular from Oliver Mintzlaff, the company’s Head of Sports.

Horner’s departure effectively ends the longest active tenure of any team principal in modern Formula 1 history. The British manager had been with the team for two decades, guiding it to multiple Drivers’ and Constructors’ World Championships with stars such as Sebastian Vettel and Max Verstappen. His leadership played a central role in building Red Bull Racing into one of the most dominant forces on the grid.

Toto Wolff now leads in seniority among team principals

With Christian Horner out, it is now Toto Wolff of Mercedes who holds the title of longest-serving team principal currently on the grid. The Austrian executive assumed his role back in January 2013, and more than a decade later, he continues to guide Mercedes through its current transition phase.

Right behind him, in terms of longevity, are Frederic Vasseur and Andrea Stella, both of whom were appointed to their current roles on the same day: December 13, 2022. Frederic Vasseur was officially announced as the new team principal of Scuderia Ferrari, replacing Mattia Binotto. Just hours later, Andrea Stella was confirmed as the team principal of McLaren, succeeding Andreas Seidl, who left to join Sauber.

Fred Vasseur formally began his work at Ferrari’s headquarters in Maranello on January 9, 2023. Since then, he has been tasked with bringing Ferrari back to championship-winning form, a goal that has remained elusive in recent years.

Different paths for Fred Vasseur and Andrea Stella after two seasons

While Vasseur and Stella were appointed at the same time, their journeys have taken markedly different paths in terms of performance and results. Andrea Stella, an experienced engineer and former race engineer for Fernando Alonso, has overseen a sharp resurgence at McLaren. Under his leadership, the Woking-based team has not only claimed a Constructors’ Championship title but is also well on its way to repeating that success—possibly even adding a Drivers’ Championship to its achievements, with Lando Norris and Oscar Piastri leading a dominant campaign in 2025.

In contrast, Frederic Vasseur’s tenure at Ferrari has been defined by ups and downs. Despite a few promising moments and race victories, the Italian team has not yet returned to consistent front-running form under his management. The pressure remains high, particularly with the comments from Ferrari CEO Benedetto Vigna, which have cast doubt over Vasseur’s long-term role with the team. These uncertainties suggest that even the relatively “longer-serving” team principals are far from secure.

F1’s team principal turnover in 2025 underscores the lack of continuity

If one word does not describe modern Formula 1, it is “continuity.” This has been especially evident in the 2025 season. In just one calendar year, half of the grid—five teams out of ten—have changed their team principals. Aston Martin, Kick Sauber (soon to be Audi), Alpine, Red Bull Racing, and Racing Bulls (Red Bull’s junior team) have all seen leadership transitions, indicating just how volatile the top management positions in F1 have become.

Such instability at the top can have widespread consequences. In a sport where long-term vision, internal culture, and consistency often underpin sustained success, this high turnover can disrupt performance and delay development. While some teams like McLaren appear to be thriving under new management, others continue to struggle with direction and identity.

As Formula 1 enters a new technical era in 2026—with sweeping regulation changes affecting both chassis and power units—the importance of having strong, stable leadership will only grow. Whether the current group of team principals can provide that kind of long-term vision remains an open question.
