Vibrations shaking the Aston Martin/Honda relationship

The situation was clearly not good at Aston Martin heading into 2026, but just how not good became truly evident on the opening days of track running in Melbourne.

Aston Martin team principal Adrian Newey faced the media for the first time on Thursday morning, sitting alongside Honda Racing Corporation President Koji Watanabe in what you might have expected to be a united front. Except it proved to be anything but.

Newey has not been team principal before, and he has not always been front and center with the press either, perhaps partly due to a refreshing aversion to toeing the party line. But in this case, that trait blindsided Honda somewhat, as Newey explained the impact of the vibrations that are hampering the team so much.

“Fernando [Alonso] is of the feeling that he cannot do more than 25 laps consecutively before he will risk permanent nerve damage to his hands,” Newey said. “Lance [Stroll] is of the opinion that he cannot do more than 15 laps before that threshold.

“I think there is no point in [not] being open and honest in this meeting. On our expectations, it is something that unfortunately Koji and I haven't had a chance to discuss properly prior to this meeting, but we are going to have to be very heavily restricted on how many laps we do in the race until we get on top of the source of the vibration and improve the vibration at source.”

Honda was aware of the scale of the problem, but not aware of the claims that the drivers were fearing permanent nerve damage. And one source close to the team laughed at such a suggestion, describing it as nonsensical political drama (though neither source was disputing a significant issue exists).

The drivers downplayed the discomfort shortly afterwards, leaving Newey alone in being so openly forthright. While Honda is the catalyst thanks to an underpowered and unreliable power unit, Newey’s decision to publicly disclose something embarrassing to the Japanese manufacturer – having not spoke to Honda about it beforehand – was a clash of cultures.

And it wasn’t an isolated incident, as Friday saw a deepening of the crisis. Alonso did not get out on track at all in FP1, while Stroll’s running was ended after three laps. Prior to the pair enjoying a slightly more productive FP2 – completing 31 laps between them but some five seconds off the pace – Newey revealed another issue.

“We are short on batteries," he admitted. "We’ve only got two batteries left, the two that are in the car, so if we lose one of those then it’s obviously a big problem. So we’ve got to be very careful on how we use the batteries.

“The critical point is the number of batteries. We came here with four batteries. We’ve had conditioning problems or communication problems with two of those batteries, which means we’ve, as we sit here today, only got two operational batteries.

“That, given our kind of rate of battery damage, is quite a scary place to be in. Obviously, we’re hopeful that we can get through the weekend and start two cars and so on and so forth, but it’s very difficult to be concrete at the moment about that.”

Asked if there was any chance of flying more batteries in from Japan for the rest of the weekend, Newey replied: “Unfortunately not. There aren’t any.”

A huge challenge though it is, clearly this is not the dream new test that Newey had envisaged when he finally started work at Aston Martin last year. The design legend admitted he feels “a bit powerless” because the problems with the power unit are preventing him from learning about the car itself.

While there was a small hint at working as a team when Newey stated “it is our problem because ultimately the car is the combination of chassis and PU,” he soon was highlighting the root cause for Honda’s struggles by revealing how resource and experience levels had dropped in recent years, insisting it came as a surprise to Aston Martin to discover four months ago.

“A bit of history is important there. Honda pulled out at the end of 2021. They then re-entered the sport, kind of, at the end of 2022, so over roughly a year, a year and a bit, out of competition. When they reformed, a lot of the original group had, it now transpires, disbanded and gone to work on solar panels or whatever, and so a lot of the group that reformed are actually fresh to Formula 1. They didn’t bring the experience that they had had previously.

“Plus, when they came back in 2023, that was the first year of the budget cap introduction for engines, so all their rivals had been developing away through ’21, ’22 with continuity, their existing team, and free of budget cap. They re-entered with, let’s say, only, I’m guessing, 30% of their original team, and now in a budget cap era, so they started very much on the back foot and unfortunately, they’ve struggled to catch back up.

“No, we weren’t [aware when signing to partner with Honda]. We only really became aware of it in November of last year when Lawrence [Stroll], Andy Cowell and myself went to Tokyo to discuss rumors starting to suggest that their original target power they wouldn’t achieve for race one, and out of that came the fact that many of the original workforce had not returned when they restarted. So, no is the answer.”

Perhaps most damning, however, was when Newey barely sidestepped a question over whether he would have preferred to have remained with Mercedes power units if the choice had been up to him, before further emphasizing a power deficit.

“I think we are where we are with Honda. Obviously, our focus now is to work with Honda to get to the best possible place. Being realistic, this season is first of all, 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.

“Then at the same time, of course, Honda needs to start working on the ’27 engine, because it’s clear that a very large step in combustion engine power is needed for ’27, and that has to be their sole focus.”

We’re only two days into the first race weekend of the new season, but already on multiple fronts it appears that it’s going to be a long and painful road ahead for Aston Martin and Honda. Not only to recover performance, but also protect some bridges that look close to catching fire.
