First, Adrian Newey. Then Christian Horner. Now, Paul Monaghan, the man who spent nearly 2 decades helping turn Red Bull’s fastest ideas into race-winning machinery, is preparing for the exit.
Monaghan, Red Bull’s chief engineer for car engineering, is understood to be leaving the Milton Keynes team for Cadillac. Red Bull has not formally announced the move, and the final timeline remains unclear. Still, the direction is loud enough. Cadillac wants proven F1 knowledge. Red Bull is watching another old pillar of its championship structure edge away. This is not a background engineer slipping out unnoticed. Monaghan joined Red Bull in 2005, the team’s first season in Formula 1. He worked through the Sebastian Vettel years, including the blown-diffuser force of the RB9, and remained central during the ground-effect dominance of Max Verstappen’s RB19 era.
Red Bull is not just losing a chief engineer. It is bleeding institutional memory right when its car, leadership and culture already face a brutal test.
Monaghan’s Value Was Built In The Garage
Monaghan’s title can sound dry from outside the paddock. Inside a Formula 1 team, it carries real weight.
A chief engineer sits close to the battle line between theory and lap time. The job means translating wind tunnel data into workable setups, helping shape race weekend priorities, reading driver feedback, and finding answers when tyres fall out of the window on a Sunday afternoon.
It also means dealing with the ugly parts of F1 performance. Parc ferme rules limit what teams can change after qualifying. Track temperature swings. Sprint weekends compress the schedule. A team can spend months designing a car, then discover on Friday that the balance disappears over kerbs or that rear tyre degradation will decide the race.
That is the territory Monaghan has lived in for years.
His expected exit lands at a difficult moment because Red Bull no longer carries the aura of total control. Verstappen has managed just 1 podium through the first 7 races of 2026, while Red Bull sits 4th in the constructors’ standings. At the Austrian Grand Prix weekend, Kimi Antonelli topped both Friday practice sessions for Mercedes, while Verstappen finished 4th in both sessions and Red Bull dealt with early technical problems.
Those facts do not mean Red Bull has lost its edge forever. They do mean every departure now feels heavier.
Mekies Tries To Hold The Line
Before Red Bull can fix the car, it has to control the noise around the team. That is where Laurent Mekies finds himself.
Mekies inherited the Red Bull job after Christian Horner left his team principal role on July 9, 2025, ending a 20-year spell that began with the team’s first F1 season. Horner’s departure already forced Red Bull into a new era. Monaghan’s expected move makes that transition feel even sharper.
During Friday’s FIA team representatives’ press conference at the Red Bull Ring, Mekies avoided a direct confirmation of Monaghan’s future. His answer was careful, but it still revealed the pressure around the subject.
Laurent Mekies said: “Paul is actually here today. He has been working very hard to get our cars out this morning.”
That was not a throwaway line. It was damage control with a paddock audience listening. Mekies had to show that Red Bull’s garage remained focused while questions about another senior exit circled the team.
He also stressed that retaining talent remains a priority. That point matters because F1 teams build confidence behind closed doors long before it ever flashes green on a timing screen. Engineers need to believe the structure around them is stable. Drivers need to believe the technical group can still deliver. Rival teams watch for cracks.
That is the bridge between Red Bull’s problem and Cadillac’s opportunity. When a champion team starts fighting to keep its people, a new team with money, ambition and open seats in its technical structure sees a chance to move fast.
Cadillac is Buying Hard-earned F1 Judgment
For Cadillac, the appeal is obvious.
The American team has entered Formula 1 with serious backing and an experienced driver pairing in Sergio Perez and Valtteri Bottas. It also has a clear roadmap: begin with Ferrari customer power before General Motors brings its own power unit in 2029.
That plan needs more than money. It needs people who know how F1 actually punishes new teams.
Cadillac can hire staff, build facilities and speak confidently about ambition. None of that replaces the kind of knowledge gained from years inside a front-running garage. Monaghan has seen title pressure up close. He has watched Red Bull turn concepts into trophies. His value comes from knowing how small decisions on a Friday can shape an entire Sunday.
You cannot buy an F1 championship. But poaching a veteran like Monaghan is one of the fastest ways for Cadillac to stop thinking like a rookie team.
His experience would help a new operation avoid the mistakes that waste seasons: chasing the wrong setup direction, misreading driver feedback, underestimating tyre behaviour, or reacting too slowly when development pressure hits.
Cadillac does not need Monaghan for headlines. It needs him for judgment.
Verstappen’s Shadow Looms Over Every Departure
Max Verstappen’s shadow now looms over every departure at Milton Keynes.
That does not mean Monaghan’s expected exit alone will shape Verstappen’s future. Drivers make career decisions around performance, trust and long-term direction. Still, the pattern around Red Bull is impossible to ignore.
Newey’s departure removed the most famous technical mind from the building. Horner’s exit ended the leadership model that defined the team for 20 years. Gianpiero Lambiase, Verstappen’s long-time race engineer and one of the most important voices on his radio, is also set for a future move to McLaren. Now Monaghan appears bound for Cadillac.
Each move has its own context. Together, they create a sharper question: can Red Bull prove the system is bigger than the people who built it?
That answer will not come from press conference lines. It will come from lap time, upgrade response and whether Verstappen feels the team can still give him a car worthy of his peak.
Monaghan’s expected departure will not end Red Bull’s competitive story. This team still has talent, resources and one of the strongest drivers in the sport. But it does mark another cut into the old Red Bull backbone.
Cadillac is chasing credibility. Red Bull is trying to protect its authority. Monaghan’s move sits directly between those 2 fights, which is why it matters more than another name on an F1 staff list.
