Aston Martin has been one of the biggest disappointments of the early 2026 Formula 1 season, and arguably an even greater surprise than newcomer Cadillac. The AMR26 arrived with huge expectations, largely because it is the first Aston Martin Formula 1 car shaped under the technical influence of Adrian Newey.
Aston Martin’s difficult AMR26 start raises big questions
But the reality so far has been far less convincing.
While Aston Martin now boasts some of the most advanced facilities in Formula 1 thanks to its state-of-the-art Silverstone campus, there is a growing sense that the team has not yet fully developed the mentality or operational cohesion of a genuine front-running outfit.
The infrastructure may be world-class, but building a championship culture takes more than impressive buildings and high-profile hires. Organisational growing pains, rapid internal changes, and an evolving technical structure appear to have created friction at exactly the wrong moment.
When Adrian Newey agreed to join Lawrence Stroll’s ambitious project, even taking a small ownership stake, he likely did not expect to step into an environment still undergoing such major upheaval, with departures and restructuring continuing behind the scenes.
The Honda gamble created unexpected complications
The radical 2026 Formula 1 regulations have already created enough complexity, with the sport shifting to a new generation of agile cars powered by a near 50/50 split between internal combustion and electric power.
For Aston Martin, however, the challenge became even greater because of its strategic decision to leave behind its previous customer relationship with Mercedes.
As a Mercedes customer team, Aston Martin previously benefited not only from access to the German manufacturer’s power unit, but also its gearbox and rear suspension architecture. In practical terms, this meant a significant portion of the rear-end package came ready-made.
By moving to an exclusive Honda works partnership, Aston Martin was suddenly forced to develop far more in-house expertise, particularly around rear-end packaging, transmission integration, and mechanical architecture.
The partnership with Honda was built on trust, given the Japanese manufacturer’s successful championship-winning era with Red Bull and Max Verstappen. However, Honda’s earlier Formula 1 exit announcement in 2020 had already shifted some of its most experienced engineers to other programmes, and its return appears to have come with a less established engineering structure.
This created major integration issues when the AMR26 project came together. The power unit has reportedly lagged behind not only in outright performance, but also reliability, with harmful vibrations affecting the chassis and even compromising battery systems.
While Aston Martin could benefit from highly favourable ADUO concessions due to its competitive struggles, the immediate focus has been damage control rather than performance gains.
Gearbox troubles and Adrian Newey’s aggressive concept
Adrian Newey has also pushed Aston Martin toward an extremely bold design philosophy, with radical aerodynamic concepts and unconventional mechanical choices. The suspension layout, both front and rear, reportedly abandons traditional wishbone configurations in favour of complex multi-link arrangements.
But one of Aston Martin’s most underestimated problems may be the transmission.
For the first time, the team has had to develop its own gearbox rather than rely on Mercedes hardware, and the lack of internal experience in this area has clearly shown. The newly created transmission department has faced typical early-development issues, with gear shifts described as either too slow or overly abrupt.
At the Miami Grand Prix, Aston Martin faced criticism for not bringing major upgrade packages, but Adrian Newey is believed to be focused on a much more significant car evolution expected closer to the summer break, possibly even as late as Zandvoort.
Instead, Silverstone engineers concentrated on electronic gearbox management improvements in Miami, aiming to reduce shift times and improve drivability. However, based on driver feedback, the changes failed to deliver the expected gains, leaving the AMR26 unstable under braking and difficult to manage under acceleration.
Could Canada offer Aston Martin its first breakthrough?
Behind the scenes, both the engine and gearbox have been undergoing dyno testing at Honda’s Sakura facility in Japan. Fine-tuning work on electronic management systems is expected to improve integration between the power unit and transmission.
That could make the Canadian Grand Prix a meaningful test.
Montreal’s stop-and-go nature places heavy emphasis on traction, acceleration, and clean power delivery — exactly the areas where Aston Martin has struggled most.
The big question now is whether Canada will deliver the AMR26’s first small but meaningful step forward, or whether Aston Martin’s painful adaptation period still has much longer to run.
