Andy Cowell – the respected former Mercedes engine guru who returned to Formula 1 with Aston Martin amid great fanfare less than two years ago – is reportedly preparing to exit the Silverstone-based squad altogether in the coming months, capping a rapid rise and equally swift sidelining inside one of the grid’s most ambitious projects.
While no formal announcement has yet been made, reports suggest the separation is less a gentle farewell and more a slow-burn fracture behind the polished green façade.
Cowell’s trajectory at Aston Martin has been anything but linear. Lured back to Formula 1 in mid-2024 by Lawrence Stroll’s lavish investment drive, the former Mercedes High-Performance Powertrains managing director arrived as Group CEO and quickly reshaped the leadership structure.
By 2025 he was both CEO and team principal – a commanding position for a man widely credited as the mastermind behind Mercedes’ hybrid-era dominance.
From Power Broker to Peripheral Figure
But Formula 1 is rarely static. The arrival of Adrian Newey – design legend, minority shareholder and technical partner – dramatically altered the internal balance of power.
Late in 2025, Newey stepped into the team principal role himself, while Cowell was reassigned as chief strategy officer, a move many observers interpreted as a clear demotion despite diplomatic wording from the team.
Officially, the reshuffle was framed as a logical redistribution of expertise, especially with Aston Martin transitioning from Mercedes engines to a bespoke Honda power unit for 2026.
Unofficially, the chemistry between two engineering heavyweights with very different philosophies was always going to be volatile: Cowell’s deep roots in power units versus Newey’s aerodynamic and chassis-centric worldview.
Now, a report from PlanetF1 indicates Cowell could finish with the team as early as June 2026 – shortly after the new engine regulations are locked in – a timeline that would neatly coincide with the diminishing need for his specific technical oversight.
Newey’s Vision – and the Unspoken Tension
Late last year, Adrian Newey was careful, at least publicly, to paint Cowell’s transition as collaborative rather than confrontational. Yet his comments reveal how the internal restructuring unfolded and why his colleague’s influence may have inevitably waned once the 2026 engine programme reached maturity.
“To be perfectly honest, it became very evident that, with the challenge of the ’26 PU, Andy’s skillset, in terms of helping the three-way relationship between Honda, Aramco and ourselves, is absolutely his skillset,” Newey told Sky Sports F1 following the confirmation of the changes.
“So he very magnanimously volunteered to be heavily involved in that through the first part of ’26.
“And that left [the question], ‘OK, well who’s going to be TP?’
“Since I’m going to be doing all the early races anyway, it doesn’t actually particularly change my workload because I’m there anyway, so I may as well pick up that bit.”
The language is courteous, even generous – but it also underscores a crucial reality: once the engine homologation milestone passed, Cowell’s sphere of influence naturally narrowed.
In a team increasingly defined by Newey’s design vision, there was less room at the strategic helm for a powertrain specialist whose primary mission had effectively been completed.
Cowell’s reported exit carries an air of inevitability rather than shock. He has remained visible – attending Honda’s power-unit launch in Tokyo and appearing at the team’s 2026 car unveiling – but insiders suggest relations have grown strained as his responsibilities shrank.
The contrast between his initial return as a central architect of Aston Martin’s transformation and his later repositioning has been stark.
For a figure accustomed to steering championship-winning operations, a strategic advisory role may have felt like a holding pattern rather than a destination.
If Cowell does indeed depart in mid-2026, it would close a brief but consequential chapter: a return to Formula 1 fueled by ambition, infrastructure promises, and the allure of building a new powerhouse — only to be overtaken by another legend’s gravitational pull.
