Aston Martin finally solves some key reliability problems in Miami
The Miami Grand Prix represented a small but significant turning point in Aston Martin’s difficult 2026 Formula 1 season. For the first time since the start of the championship, both Fernando Alonso and Lance Stroll managed to reach the checkered flag with the two AMR26 cars. On the surface, it may appear to be a modest achievement, but after a disastrous opening phase marked by heavy criticism and repeated technical retirements in Australia, China and Japan, the result carried important meaning for the Silverstone-based team.
Fernando Alonso sees improved reliability but no real pace
The core of Aston Martin’s early problems was linked to the violent vibrations generated by the new Honda power unit, an issue that had already emerged during pre-season testing in Bahrain. Thanks to the five-week break and close collaboration with Honda engineers in Sakura, effective countermeasures were introduced on both the chassis and engine side.
The work completed in Japan reportedly eliminated the resonance problems that had been systematically damaging internal components of the AMR26.
Or at least, that is the official version. Many observers noticed Fernando Alonso stretching his left hand at the end of practice sessions in Miami, almost as if it had gone numb. What is certain, however, is that with both cars reaching the finish line, the vibration issue — even if not completely eliminated — appears to have been reduced significantly.
The Spanish driver sounded unusually optimistic, emphasizing that solving the vibration problems represents the most important step forward of Aston Martin’s season so far. The two-time Formula 1 world champion finished fifteenth in Florida, while openly admitting that outright speed still remains a distant dream for the team.
Lance Stroll appeared considerably less satisfied. The Canadian finished seventeenth and complained about a chronic lack of aerodynamic load and engine power. His two-stop strategy failed to produce results and further highlighted how the AMR26 remains too slow compared to its direct rivals.
Although Stroll acknowledged the reliability improvements, the frustration of driving a car stuck near the bottom of the standings remained obvious throughout the weekend.
Honda and Aston Martin shift focus from survival to optimization
From Honda’s side, technical director Shintaro Orihara confirmed that the data collected in Miami validated the effectiveness of the solutions introduced to combat the mechanical failures seen earlier in the season. The Japanese manufacturer will now shift its focus toward optimizing energy management and improving the overall drivability of the power unit.
According to Orihara, there is still considerable room for improvement regarding the delivery of electric power throughout the lap.
Mike Krack defended the work carried out by Aston Martin, praising the speed with which engineers managed to resolve what he described as extremely complex and extraordinary technical problems. The Luxembourger nevertheless urged caution, openly recognizing that the performance gap remains enormous.
It will not be a recovery achievable within a single week, which is why the team has no intention of making unrealistic short-term promises. Aston Martin’s strategy remains focused on extracting the maximum potential from the current package before introducing major aerodynamic changes later in the season.
Gearbox concerns remain another major weakness
At the moment, Aston Martin shares the bottom of the constructors’ standings with Cadillac, as the only two teams still without points in the championship. The deliberate decision not to introduce aerodynamic upgrades in Miami allowed the team to focus entirely on stabilizing the foundations of Adrian Newey’s AMR26 project.
Even so, the car continues to operate with worrying performance deficits. Team management fully understands that without a major increase in aerodynamic efficiency, scoring points will remain an unrealistic objective.
The outlook for the next races therefore remains one of survival at the back of the field while waiting for the larger development package scheduled after the summer break. At the same time, the team must also address the gearbox problems highlighted by Alonso.
The road ahead for Aston Martin remains extremely difficult. Internally, there is already growing acceptance that the 2026 season may effectively be compromised. More worrying still is the feeling that the enormous gap accumulated relative to the rest of the Formula 1 grid may prove very difficult to recover — not only this year, but potentially next season as well.
