Certainly, the Honda engine is an obvious weak point. It lacks power and suffers from reliability issues, including significant vibrations under real-world conditions.

But these vibrations, precisely, clearly illustrate the core of the problem: they are acceptable on a test bench, but become critical once integrated into the car. This suggests an integration flaw rather than a problem purely related to the power unit.
As Honda has acknowledged, the way the power unit is mounted in the chassis amplifies these phenomena, which directly implicates Aston Martin’s responsibility.
Overestimated potential
On the chassis side, the observation is even more worrying. The AMR26 is deficient in all key areas: top speed, performance in fast corners, traction on exit. The lack of aerodynamic downforce is particularly critical, with minimum cornering speeds up to 20 km/h lower than the best cars. Added to this is a weight problem — the car is not at minimum weight — which further penalizes all phases of performance.
The statements from the team principal and car designer
Adrian Newey at the start of the season, suggesting an immediate Q3 potential on the chassis side, now appear largely optimistic. For this analysis to be correct, the Honda engine alone would have to represent a deficit of more than two seconds per lap, which no one in the paddock considers credible. The current assessment tends rather towards shared responsibility, or even a chassis more problematic than the engine.
Lack of cohesion
In charge of operations, engineer Mike Krack adopts a much more clear-eyed stance:
Aston Martin faces a “mountain to climb,” and this also includes its own technical choices, such as the design of a potentially overweight internal gearbox. The overall project suffers from a lack of coherence, which is particularly penalizing in a 2026 regulation where everything is interconnected through energy management.

This situation highlights a classic difficulty of new team/engine manufacturer partnerships: trying to optimize both the chassis and the engine simultaneously can lead to harmful compromises. For example, Aston Martin’s demands for a more compact engine forced Honda to revise the integration of many peripheral elements, which may have weakened the whole, a mistake already made by
McLaren in 2015.
Disappointing for Alonso…
On
Fernando Alonso’s side, the discourse is pragmatic: he does not expect a major transformation in the short term. The planned developments should bring marginal gains (weight reduction, improved balance), but a deeper overhaul seems postponed to the second half of the season, or even the next technical cycle.
Aston Martin is today the typical example of an underexploited project: an engine in difficulty, but not solely responsible, a fundamentally poorly conceived or misunderstood chassis, and a faulty overall integration in an era where everything must work in symbiosis.
The potential mentioned may exist, but it is currently theoretical. Without structural correction, the AMR26 will remain a package far below its ambitions, and probably one of the most disappointing of this new regulatory era.
