Why was Christian Horner sacked as Red Bull F1 team boss?

4 hours ago 1

Christian Horner has been sacked as Red Bull team principal with immediate effect after 20 years, the Red Bull Racing Formula One team announced on Wednesday.

The 51-year-old oversaw a period of dominance by the team, winning the drivers’ championship eight times – including the past four titles with Max Verstappen – and adding six constructors’ crowns.

Who will replace Horner at Red Bull Racing?

Horner, who has been in charge of Red Bull since the team was formed in 2005, will be replaced by the principal of sister team Racing Bulls, Laurent Mekies.

A motorsport aerodynamics specialist, the French-born Mekies entered Formula One in the early 2000s and had stints working with Arrows, Minardi, Toro Rosso and Ferrari before joining Racing Bulls as team principal in 2024.

“I think he has a very, very good understanding of the business, having started as an engineer and then worked at the FIA,” said Fred Vasseur, current F1 team principal at Ferrari, when Mekies left the famous Italian team in July 2023.

No reason given for Horner sacking

Horner was sacked as Red Bull’s team principal with immediate effect.

The team’s official media statement, released on Wednesday, reads:

“Red Bull has released Christian Horner from his operational duties with effect from today [Wednesday, July 9, 2025] and has appointed Laurent Mekies as CEO of Red Bull Racing. Oliver Mintzlaff, CEO Corporate Projects and Investments, thanked Christian Horner for his exceptional work over the last 20 years.”

“We would like to thank Christian Horner for his exceptional work over the last 20 years,” said Mintzlaff. “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.”

Martin Brundle, an ex-F1 driver, current race commentator and friend of Horner, told Sky Sports News:

“I am due to speak to Christian later. I put a message to him saying, ‘I am sorry to read this, can we have a chat before I am due to go on TV because I want to know more about it from his point of view’.

“He wasn’t able to do that. What he did say was that no reason was given to him as to why he is being released.”

A difficult 18 months for Horner

Horner’s dismissal follows a challenging period on several fronts for the team principal.

His exit from the team comes nearly a year-and-a-half after it was leaked that a female employee had accused Horner of sexual harassment and coercive, controlling behaviour. Horner was twice cleared of the claims by Red Bull headquarters, situated in Austria.

At the same time, Max Verstappen’s father, Jos, called for Horner to leave his position and claimed that the Briton’s presence could tear the team apart in a March 4, 2024, interview.

Jos told The Daily Mail that “there is tension while he remains in position”, referring to Horner.

He added, “The team is in danger of being torn apart. It can’t go on the way it is. It will explode. He is playing the victim when he is the one causing the problems.”

The early-2025 departure of Adrian Newey – the former chief technology officer of Red Bull Racing and widely considered one of the greatest motorsport designers in F1 – to rival team Aston Martin was a huge loss to the Milton Keynes-based team and to Horner personally.

Newey had joined Red Bull in 2006, just months after Horner’s appointment, with the pair forming one of the most successful F1 management partnerships in history.

How successful was Horner as Red Bull boss?

Under Horner’s leadership, Red Bull won their first world championship in 2010, with German driver Sebastian Vettel taking the first of four consecutive drivers’ titles.

Following a multiyear period of dominance by archrival Mercedes, Red Bull, this time with Max Verstappen of the Netherlands as their star driver, entered a second championship window, winning four more drivers’ titles consecutively from 2021 to 2024.

In 2023, Horner presided over the most dominant season in Formula One history, with the team winning 21 of 22 races, and Verstappen setting a new F1 record with 10 consecutive victories.

Will Max Verstappen stay at Red Bull Racing?

At the midway point of the 2025 season, Verstappen trails McLaren duo Oscar Piastri and Lando Norris in the drivers’ standings and has all but conceded the drivers’ title for this season.

As far back as April 13, Verstappen was already pessimistic about the prospects of winning a fifth straight drivers’ championship.

“McLaren are not my rivals right now. I am just taking part in this world championship,” Verstappen said, as quoted by nl.motorsport.com.

When pressed further if he meant he doesn’t see himself competing for the 2025 drivers’ title, he replied: “No, I don’t.”

In recent days, and not for the first time, Verstappen has been linked with a move to rival Mercedes, possibly as soon as next season.

Brundle told Sky Sports News that Horner’s exit from Red Bull may defuse tensions, resulting in Verstappen re-signing with the only F1 team he has ever driven for.

“It makes it more likely that Verstappen will stay,” Martin Brundle said. “It became personal in Team Verstappen.”
