Aston Martin has taken a small step forward: at Suzuka, vibrations were reduced thanks to a solution tested on Friday, although it was not used on either Saturday or Sunday. For the first time this season, an AMR26 completed the full race distance, providing valuable data to analyze ahead of the Miami Grand Prix.
For the first time this season, Aston Martin managed to bring at least one of its cars to the chequered flag. However, there is not much to celebrate, especially as Lance Stroll was forced to retire due to a water leak from the internal combustion engine. Still, achieving more ambitious goals requires starting with small steps and acknowledging them, as in this case.
It is no secret that, before arriving in Australia, the AMR26 struggled to complete sufficient mileage to run a full race, with runs limited to around twenty laps due to severe vibrations. This phenomenon put not only the drivers under pressure — as seen in China, where Fernando Alonso was forced to retire due to a near loss of sensitivity in his hands and feet — but also the battery, which tended to fail under such conditions.
In recent events, it was not uncommon to see Honda and Aston Martin mechanics working intensively even between sessions, not so much to refine the setup or complete preparations, but rather to resolve power unit issues that were limiting track time. In Japan, however, the weekend was noticeably smoother, representing a small but encouraging sign for the team.
One of the main issues that has slowed down the AMR26 relates to strong vibrations, and on this front the Japanese Grand Prix weekend offered some interesting insights. Behind the scenes, Honda is working intensively to resolve the issue, which, as highlighted in recent races, is not linked solely to the engine but also to the chassis, which acts as a kind of resonance chamber, amplifying the phenomenon.
The vibrations reached the steering wheel and the pedals — the points where the drivers’ hands and feet are anchored. During testing, Honda had even requested maintaining a higher fuel level to partially dampen the effect. However, this was only a temporary solution, and the need for a deeper intervention quickly became evident.
For this reason, work is ongoing on two fronts together with Aston Martin engineers, addressing both the chassis side and the power unit. Honda had indicated that the objective was to have an initial solution ready for Suzuka, its home race, which, although not definitive, could gradually help reduce vibrations. Indeed, something was tested on Friday, before being removed on Saturday.
Speaking after qualifying, Fernando Alonso explained that, from a driver’s perspective, the solutions tested during free practice had delivered clear benefits, improving the situation by around 80% in his view: “Yes, from the tests and compared to the first two races, what we tried yesterday improved things by 80%,” the Spanish driver said at Suzuka.
This was positive news for the team, even though those updates were later removed and not used in the race. “We had some countermeasures to push things a bit further. There was an issue: during the sessions we tested a component that represented a step forward, but we were not in a position to use it in the race,” explained Mike Krack, head of trackside operations, after the Grand Prix.
“We are experimenting with several solutions. However, introducing new components always carries a certain degree of risk, and that must be weighed when making decisions related to reliability. These were freshly produced parts, so we preferred not to run them in the race. That said, the potential is there.”
While waiting for more definitive solutions, which will require time, it is clear that even reducing the vibrations reaching the steering wheel can help limit the numbness in the hands that has already affected both Alonso and Stroll in these early races. The encouraging aspect is that the feedback from Friday’s test was positive, and there will now be time to carefully analyze all the data collected.
The April break offers an opportunity to work both on reliability and performance, but at Silverstone there are no illusions about finding a miracle solution capable of transforming competitiveness overnight, especially as all rivals are expected to introduce updates in Miami during the first race weekend of May. Nevertheless, completing a full race distance provides a significantly larger pool of data.
“We completed the full race distance, and that is a good step forward in terms of reliability. In addition, we have worked extensively to improve battery reliability. At the same time, at the Sakura factory we are working intensively to increase engine performance and to evaluate and optimize energy management,” added Shintaro Orihara, one of Honda’s key figures.
“It is a multi-front effort. Even developing engine performance from a mechanical perspective is not a short-term task, so we continue to work hard in the background to improve it. Today, however, we gathered a lot of data over a full race distance — information that will help us improve drivability and energy management. These are valuable insights ahead of the next four weeks leading up to Miami.”
