After winter testing in Barcelona and Bahrain already proved problematic, the first weekend of Formula 1’s new era is unfolding even worse for Aston Martin. During the first free practice session Fernando Alonso was not able to take part at all, while Lance Stroll completed fewer than a handful of laps.
The big problem? Honda only has two batteries available and if something happens to one of those, it would mean the end of the race weekend for one car. The Silverstone-based team has to be extremely careful with all mileage in order to even take the start on Sunday, for which it must also comply with the 107% rule in qualifying – although the FIA can still grant permission if they fail to meet it.
Aside from this first concern about whether Aston Martin will be able to take part in Melbourne, there are multiple problems that go much further than that. While all other teams are trying to get a clear picture of their performance and the early pecking order, Aston Martin is absolutely not at that stage yet. For now, it is purely about survival for Lawrence Stroll’s ambitious project.
Most of this goes back to the severe vibrations Honda is struggling with. Those destroyed several battery cells in Bahrain, which is why there is now a shortage of parts Down Under.
A large deficit with the internal combustion engine?
The consequences are twofold, as Newey explained on Friday. On the engine side, Honda needs to focus on a significant performance deficit with the internal combustion engine, but that is not yet possible because vibrations – and therefore reliability issues – overshadow everything.
“I think there’s a very clear action on Honda to try to reduce the vibration,” Newey said in the FIA press conference. “They are working on that. It’s not going to be a quick fix because it involves fundamental balancing and damping projects that they will need to conduct. I can’t comment how quickly they can achieve that but that has to be the main drive.
“Once they’ve got past that then they can really start to concentrate on performance but at the moment this vibration issue is sucking all energy in every area.”

That does not change the fact that the shortcomings in terms of pure power are significant. To outsiders those issues appear mainly to lie on the electrical side of the power unit, but Newey has explained that most of them can in fact be traced back to the internal combustion engine.
Because the ICE is not powerful enough, Honda has to compensate by deploying more electrical power in certain parts of the track. But this means that there is no energy left to deploy for the second half of the straights, exactly where drivers actually need that electrical power.
With the ADUO system, there is a safety net for Honda to use. Manufacturers that are more than four percent down on power with the internal combustion engine receive two additional upgrades from the FIA after six race weekends, but Honda will need many more steps like that. And as Newey explained, behind the scenes the time is already ticking for a big step in 2027.
“Being realistic this season is first of all, as I mentioned, getting on top of this vibration problem so we can run reliably and from there to see how much performance they can add to the combustion engine in particular,” Newey explained.
“Then at the same time of course Honda need to start to be working on the 2027 engine because it’s clear that a very large step in combustion engine power is needed for 2027, and that has to be their sole focus.”
Honda limits low-fuel running, Newey lacks data for car development
Besides the engine-related issues, it also has a major impact on Aston Martin’s own car development. Newey explained during media day at Albert Park that his team currently has the fifth-fastest chassis on the grid, roughly three quarters of a second to a full second behind the very front.

But the 2026 season will more than ever be a development race. And in precisely that development race Aston Martin is extremely limited by Honda’s engine problems. Due to the limited running Newey cannot learn as much about the chassis and aerodynamic platform of the AMR26 as he would like to.
“I think it’s one where I kind of feel a bit powerless because we’ve clearly got a very significant PU problem and our lack of running also means at the same time we’re not finding out about the car,” he said. “Our information on the car itself is very limited because we’ve done so little running and particularly running at low fuel. Honda have limited us very much to how much low fuel running we can do.”
The latter is crucial. Because a higher fuel load can help to mask some of the problems with the battery, Honda has encouraged Newey’s team – if they are able to run at all – to run with slightly more fuel onboard. But to find the absolute limit of the car, low-fuel runs are crucial. That is precisely the information Newey is now missing for the further development of his creation. And exactly that aero development was a crucial part of his development philosophy, as the legendary designer initially only focused on the fundamentals because of his late start.
“So it just becomes a self-feeding problem, and of course, it’s using a lot of energy in the human sense as opposed to the kilowatt sense, on our part to try to work with Honda and to produce the best overall solution. We can turn around and say well it’s not our problem, but this is our problem because ultimately the car is a combination of chassis and PU.”
On the engine side Honda needs to address its deficit with the internal combustion engine, but reliability problems overshadow everything, while on the chassis side Aston Martin is missing crucial data.
The first part of this season has long since been written off, but on both fronts the consequences of this false start may go much further than just a painful showing in Australia and Asia.
