Ford says it is “frustrated” with the lack of transparency concerning Red Bull’s investigation into allegations levied at Formula 1 Team Principal Christian Horner.
Horner is currently the subject of an investigation from Red Bull’s parent company following accusations of alleged inappropriate behaviour against a colleague.
The Red Bull boss, who attended a hearing with an external barrister earlier this month, has denied the allegations and claimed the F1 outfit remains “united”.
Horner has continued to manage his responsibilities at the helm of Red Bull, a role he has overseen since its inception in 2005, while the investigation continues.
Ford, who has been absent from F1 since 2004, is embarking upon a “long-term strategic technical partnership” with Red Bull to collaborate on a 2026 powertrain.
Global Head of Ford Performance Motorsport Mark Rushbook stated last week that the brand expects “high standards of behaviour” from all its relevant partners.
Now, according to a letter which has been read by the Associated Press, Ford CEO Jim Farley has urged Red Bull to give “prompt and serious attention” to the issue.
Farley has written that Ford is “increasingly frustrated by the lack of resolution or clear indication from you about when you anticipate a fair and just resolution of this matter.
“We are likewise frustrated by the lack of full transparency surrounding this matter with us, your corporate partners, and look forward to receiving a complete account of all findings.”
Farley reiterated the stance that Ford’s status as a family-owned company meant that its core values remain “non-negotiable” when it came to associated partners.
“As we have indicated previously, without satisfactory response, Ford’s values are non-negotiable,” it added.
“It is imperative that our racing partners share and demonstrate a genuine commitment to those same values.
“My team and I are available at any time to discuss this matter. We remain insistent on, and hopeful for, a resolution we can all stand behind.”
Horner was present at both Red Bull’s Milton Keynes base when it launched its 2024 car, the RB20, and for the entirety of pre-season testing in Bahrain last week.
Amid Horner being asked questions on the investigation, Formula One Management released a statement hoping it would be concluded at the “earliest opportunity”.
