Christian Horner, who has served as the Red Bull team principal for two decades, was dismissed on Wednesday. During his tenure, he achieved eight Formula 1 drivers’ championships, gaining celebrity status along the way.

While Red Bull didn’t specify the reasons behind this decision, the official statement expressed gratitude for Horner’s contributions and noted that he will “always be a significant figure in our team’s history.”

Laurent Mekies of sister team Racing Bulls will replace Horner in his role as chief executive of the Red Bull team.

Horner had been Red Bull team principal since it entered F1 as a full constructor in 2005.

He had performed his team and media duties as normal throughout the British Grand Prix last week.

Under Horner’s leadership, the team clinched eight drivers’ championships — four with Sebastian Vettel and four with Max Verstappen — in addition to six constructors’ championships.

But McLaren has dominated this season in F1, while Red Bull’s performance has dipped, though defending champion Verstappen remains third in the standings and the team is fourth.

Uncertainty for the future

Horner spent much of last week fielding questions over Verstappen’s future at the team after the Dutch driver declined to commit to stay with Red Bull for 2026. Zak Brown, boss of rival McLaren, told The Associated Press last week it would be a “disaster” for Red Bull if Verstappen were to leave.

Horner is the latest in a series of high-profile executives to leave the team over the last year and a half.

Car design great Adrian Newey joined Aston Martin and sporting director Jonathan Wheatley departed for Sauber, which is soon to become the Audi works team.

The team also shuffled drivers, dropping Sergio Perez at the end of last season before a brief failed experiment with Liam Lawson as Verstappen’s teammate, before he was replaced by Yuki Tsunoda, who hasn’t scored a point in five races.

“We would like to thank Christian Horner for his exceptional work over the last 20 years,” Oliver Mintzlaff, Red Bull’s chief executive for corporate projects and investments said in a statement.

“With his tireless commitment, experience, expertise and innovative thinking, he has been instrumental in establishing Red Bull Racing as one of the most successful and attractive teams in Formula 1. Thank you for everything, Christian, and you will forever remain an important part of our team history.”

The announcement comes more than a year after Horner was accused of misconduct toward a team employee.

An investigation conducted on behalf of the Red Bull company dismissed the allegation, as did a further investigation conducted after the employee appealed against the initial ruling, Red Bull said at the time.

Horner remained in charge of the F1 team throughout the entire process.

Red Bull’s next challenge

Horner’s departure comes in the middle of the team’s efforts to prepare for one of the biggest rule changes in F1 in decades next season.

At Racing Bulls, whose cars have sometimes outperformed the main Red Bull team this season, Alan Permane will be promoted from racing director to team principal to fill the gap left by Mekies.

“The spirit of the whole (Racing Bulls) team is incredible, and I strongly believe that this is just the beginning,” Mekies said in a statement released by Racing Bulls, which did not mention Horner.

“Alan is the perfect man to take over now and continue our path. He knows the team inside out and has always been an important pillar of our early successes.”
