Gearbox insufficient, chassis not well integrated
In addition to their Honda partnership, another impactful change for has been Aston Martin’s production of their own gearboxes.
Unlike previous seasons, the Silverstone-based operation is now making their own gearboxes. In the past, this responsibility was outsourced to Toto Wolff’s Mercedes.
On paper, this change gives Aston Martin complete control of their own fate. A team with full developmental overview of their engine and gearbox has more freedom than a customer team that relies on a manufacturer for certain components.
Simultaneously, this additional autonomy puts more pressure on Aston to put everything together.
At present, this is proving a great challenge. Whilst Honda’s power unit is not at the required level, the AMR26’s gearbox brings its own set of problems.
The gearbox has serious limitations and, per multiple outlets, struggles to meet the demands of these 2026 cars. Given how important gear shifts have become in order to harvest electrical energy, this is a massive vulnerability.
More basic issues, such as those brought by the AMR26’s ultra-compact design, are also present. Aston Martin are therefore not only under pressure to improve specific components, but also how they interact with each other as a cohesive unit.
This speaks to the core of the problem with Adrian Newey’s outfit. It would be overly reactionary to dismiss some of the compliments given to the AMR26 when it first debuted.
Aston’s 2026 package is undeniably bold and, aerodynamically, has some intriguing elements.
However, it is impossible to meaningfully assess the car’s potential when fundamental areas are lacking. In some sense, the team must take a few steps back if they want any hope of being able to move forward.
Reports from the paddock suggest that Adrian Newey remains confident that Aston Martin can recover. In terms of the AMR26’s chassis and overall design concept, the main issues have been identified and – at least on paper – solutions are being developed.
The AMR26 that arrives in Melbourne will look very different to the one currently in Bahrain.
Still, this does not erase the steep hill that the Silverstone-based team must overcome. It is understood that an updated engine spec will be ready after roughly one third of the season.
At roughly round 7 or 8, therefore, Honda hope to deliver a more competitive and reliable power unit. Andy Cowell, formerly team principal, is overseeing its development in Sakura Japan.
Because of how significant the deficit could be, Honda can capitalise on certain regulatory clauses that give them more resources to pour into development and close the gap.
Until then, however, it will be a painful process of learning for Aston Martin – who expect to occupy the lower positions when the season commences.
