Aston Martin’s decision to abandon Mercedes power and align with Honda for the 2026 regulations was bold. Three races into the new era, it looks deeply problematic.
While Mercedes have emerged as the benchmark — taking pole position and victory at every round so far — Aston Martin find themselves anchored to the back of the field. The contrast could hardly be sharper.
The numbers tell a bleak story. Aston Martin have recorded just one race finish this season, with Fernando Alonso crossing the line in P18 at Suzuka. Reliability concerns, a clear lack of pace, and severe vibration issues have defined their campaign.
The situation has already triggered tension between Aston Martin and Honda. Although Honda deny that the relationship is deteriorating, both parties have publicly shifted responsibility onto the other.
Adrian Newey, who has stepped down as team principal to focus on developing the AMR26, was quick to point toward Honda. Yet at Suzuka, Honda’s “top officials” countered by blaming Aston Martin for the vibration problems, insisting the issue only emerged once the power unit was integrated into the chassis.
The vibrations are serious enough to raise health concerns for both Alonso and Lance Stroll — an alarming development just three races into a regulation cycle.
Compounding matters, Aston Martin have admitted that the Newey-designed chassis is not competitive in high-speed corners. According to a “very senior and knowledgeable figure” cited by Andrew Benson via BBC Sport, more than half of the team’s performance deficit stems from the chassis.
The precise split between chassis and engine losses may never be fully quantified. But the overall picture is clear: the package is fundamentally uncompetitive.
On average, Aston Martin are 3.6 seconds off the pace across all 2026 qualifying sessions, including the China Sprint.
Newey himself acknowledged in Australia that the chassis made Aston Martin the “fifth-best team”, though he admitted deficiencies elsewhere. The data does not support that claim in practice.
The fifth-fastest team on average is Alpine, now powered by Mercedes after shutting down their factory engine operation in 2025. Alpine sit 1.268 seconds off the pace.
Aston Martin, by contrast, are approximately 2.3 seconds adrift of that fifth-place benchmark. With the majority of that gap attributed to the chassis and the remainder to the engine, the conclusion drawn from GPS data is stark: with a Mercedes power unit, Aston Martin would likely be level with Alpine.
Instead, they remain rooted near the back.
The public blame game is an unhealthy dynamic so early in a long-term partnership. Honda maintain that relations remain stable, but visible friction undermines confidence.
At Suzuka — Honda’s home race — Aston Martin adopted a “mouth shut” approach, aware that open criticism would be ill-judged. That restraint may prove essential moving forward.
Jolyon Palmer observed that Aston Martin are making Alonso look like a “test driver”, with Suzuka marking the first race he managed to finish. For a team that entered the season amid significant winter hype, that is a damaging narrative.
A one-month break in the calendar offers a timely opportunity for recalibration. Aston Martin must address both the structural performance weaknesses of the chassis and the integration issues surrounding the Honda power unit.
The longer-term question looms large: can this partnership recover its footing before the project’s wider ambitions are compromised?
With just one year remaining in Lawrence Stroll’s five-year plan before 2027, the trajectory needs to change — and quickly. For now, Mercedes’ dominance only sharpens the regret surrounding the decision that reshaped Aston Martin’s future.
