Newey has decided to leave Red Bull after a two-decade stint as the team's stalwart designer, playing an instrumental role in designing the cars that propelled Sebastian Vettel and Max Verstappen to a total of seven drivers' world championships and six constructors' titles for Red Bull.
The news of Newey's impending departure was first reported by German outlet Auto Motor und Sport and since been confirmed to Autosport by sources with knowledge of the situation.
Despite only signing a fresh Red Bull deal last year, Newey's future at the Milton Keynes squad has been the subject of intense speculation in recent weeks.
Red Bull is still embroiled in an ongoing internal power struggle between the Thai side of the business, which supports team principal Christian Horner, and the Austrian side including team advisor Helmut Marko.
The issue came to a head at the start of the 2024 season after an internal investigation into allegations of misconduct by Horner against a female member of staff, a probe which dismissed the claims against the 50-year-old.
Newey is understood to be unsettled by Red Bull's situation and the saga around Horner, which has led to a shock decision to inform the team management that he has decided to walk out.
