Alonso also implied the same thing. He said the AMR26 in Melbourne will be very different from the tests.

I just hope these upgrades address the vibration issues they are experiencing first. Then run reliably for the full 3 hours of practice 1-3, with both cars without any break downs. Aston needs a lot of mileage to get not only the car to a good baseline, but both Alonso and Stroll have had minimal running to learn how to drive these new cars at all. Simulator work is not the same as miles on track adjusting to the feel of the car, and trying different set ups, and deployment methods. Next weekend will tell us how much on the back foot they really are, and if the team have some fixes in place already. Or will this be another loooooong season again for Alonso fans.
On youtube "The race" said the parts AMR GP and Honda are trying to use to fix the issue aren't part of the homologation.V10FURY wrote: ↑28 Feb 2026, 19:57I just hope these upgrades address the vibration issues they are experiencing first.

I don't really understand this but I guess its not an obviously bad vibration, it's just at the right harmonic to make the battery fall apart?PlatinumZealot wrote: ↑28 Feb 2026, 22:46The vibration issues is harkens back to the Mclaren days.
It is two fold. The engine is producing vibrations at certain frequencies that is causing resonance, or underdamped vibrations at one or more places in the chassis and this is shaking the battery compartment.
Two things can happen: modify the engine to counter vibrations with tuned stiffness in the gears, mounts bearings etc or with dampeners. Could be the MGUK or the oil pump or the cam drive.. Or from combustion.. We do not know.. Or the second thing is obviously to modify the chassis side by either increasing stiffness to raise the naturalfrequency above that of the vibrations from the engine or add a few dampers here and there.
Both solutions will not be trivial!
Honda changed this for the 2021 engine, and I recall RBPT using a very similar design in an early prototype photo. RBPT seems to have taken it to an even more extreme level with their 2026 unit though.
You make a good point. Changing to a '2-stack' setup for the ES & CE (where the control electronics are now closer to and less isolated from the ICE) especially a late change, would help explain why they ran into issues with a (largely similar) part that was without issues for so many years at Red Bull.ispano6 wrote: ↑28 Feb 2026, 00:40The issue stems from the compounding of drivetrain vibrations that result from running the car on track.
It also looks like the ES+CE butts up against the ICE. Could they distance this in some way that the drivetrain vibration doesn't transmit as much directly? Is the chassis itself flimsy?
It's the reason they weren't pushing the car since Spain, they claim. The vibration could be coming from the gearbox or many things.Rasoose wrote: ↑01 Mar 2026, 03:07You make a good point.

The good news is it seems they'll finalize a solution during the Australian GP and expect to have it completely taken care of by China.
I don't think this battery/CE issue they ran into on the 2nd-to-last day of testing was the reason they'd been running de-tuned and with a limited top-speed though, so hopefully the other issues (presumably gearbox + half-shafts, etc.) are resolved as well or they may still have to run in a lower power mode for a while.
