Thanks. An interesting read.ispano6 wrote: ↑27 Mar 2026, 09:46Grasping at straws? You don't think like an engineer then.
From Yasuaki Asaki's active F1 column, in his own words.
https://sportiva.shueisha.co.jp/clm/mot ... 27/f1gppu/その推測が当たっていたら、オーストラリアGPと中国GPの開幕２連戦はおそらくあとづけの対策になったと思います。私の経験的に短時間での効果的な振動対策は、ダイナミックダンパー（動吸振器）のあとづけや、つっかえ棒のような部品追加での剛性アップです。
"If that guess was correct, the opening two rounds at the Australian GP and Chinese GP were probably retrofitted countermeasures. From my experience, effective short-term vibration countermeasures include retrofitting dynamic dampers (tuned mass dampers) or increasing rigidity by adding parts like struts."
It doesn't support your argument though. He speculates that the Honda engine developement leader is to blame, that he accepted late re-designs. I no way he blames the chassis.
What you quoted separately means they added mass to the car, to decrease vibrations, which he assesses that it didn't work. (unsurprisingly).
Though you highlighted struts, in no way he says it's because, or for the chassis. I guess the K might be vibrating around because it's only mounted at one end to the engine, which could certainly magnify the problem. Struts would help here for sure. He also says that the PU is the cause that generates the vibrations.
This is a tad contradictory to the other article. However I see no-one in particular quoted for these assertions.ispano6 wrote: ↑27 Mar 2026, 10:56https://sportiva.shueisha.co.jp/clm/mot ... /17/f1_20/The vibrations generated by the ICE (internal combustion engine) are not particularly significant on their own, even when compared to ICEs from previous years. Even in VTT (bench test) conditions, where the engine is connected to Aston Martin’s dummy monocoque and gearbox, there are no vibrations at levels that would be considered problematic.
However, once all the components are installed and the car is actually driven on the track, the vibrations are amplified.
Initially, the battery—which is directly connected to the ICE and the monocoque—was damaged, and drivers also reported experiencing vibrations. To ensure reliability, “vibration countermeasures for the battery” were urgently implemented and achieved some success. At the Chinese Grand Prix, the only issue that occurred throughout the weekend was a power supply problem experienced by Lance Stroll during the race (the cause is currently under investigation).
However, since no measures have been taken to reduce vibrations originating from the chassis itself, it is only natural that drivers continue to suffer from vibration issues.
There are limits to how much vibration from the ICE itself can be suppressed, as mentioned earlier, since the vibration levels from the ICE are already within normal ranges. If cockpit vibrations are truly severe enough to prevent drivers from finishing the race, it is obvious that relying solely on ICE-side measures will not lead to a fundamental solution.
“We are working together [with Aston Martin and Honda] to make improvements. We are discussing what the optimal measures are to mitigate the current issues and are moving forward with improvements together. Ideally, we would address the root cause, but what we are working on with Honda is what we can achieve within the limited time available.”
The fact that Alonso says his hands AND feet lost sensation is a bit suspect. His feet? In any case, there are many who doubt that the issue is solely Honda's doing. For it would be arrogance to not question the chassis package as a major contributor to the effects.
I don't know why you think that is suspicious. Vibrations don't just stop. The CF monocoque is rigid, it shakes from nose to rear crash structure.
