Aston Martin arrived in Japan talking up fixes and a clearer picture, and left Suzuka with the same uncomfortable truth: the AMR26 is slow in more than one way, and pointing the finger at Honda alone won’t make it disappear.
Lance Stroll didn’t hide the pain on the stopwatch after qualifying, with Aston Martin again anchored near the back. The straight-line deficit has been obvious since the opening rounds of this new regulatory era, but Stroll’s read on it was tellingly blunt — and notably shared between the factory in Silverstone and Honda’s new works effort.
“I think it’s a combination of power unit and the car,” Stroll said at Suzuka. “We’re definitely losing huge amounts of time on the straights, but we’re not the rippiest beast in the corners. So it’s a combination of things.”
That last line is the key. In the early weeks of 2026, when everyone in the paddock is still trying to separate genuine concept problems from teething issues, it’s tempting to simplify the Aston story into “new partner, undercooked engine”. Honda itself had acknowledged heading into its home race that outright performance still wasn’t where it wanted it. But Aston’s problem doesn’t stop at the end of the main straight; the car isn’t giving back the time elsewhere, and that’s what makes the situation heavier than a single weak area.
It also complicates the narrative around the measures Aston has already been taking to get through races. After China, Fernando Alonso indicated the team had been turning down Honda’s RPM to manage vibrations felt in the cockpit — a compromise that, in the short term, is survivable only if the chassis gives you something to lean on. At the moment, it isn’t.
Stroll was asked directly in Japan how much of the deficit was tied to a turned-down power unit. His answer didn’t bite, but it didn’t absolve anyone either. The implication was clear: yes, the straights hurt, but the AMR26 isn’t bailing the team out in the technical sections. That’s a bigger structural problem because it limits the team’s ability to “develop out” of trouble quickly; you can chase drag, efficiency and energy deployment, but if the underlying aero platform isn’t working, you end up chasing your tail.
Suzuka, of all places, tends to expose those half-measures. It’s a circuit that punishes a lack of confidence in the car’s balance and rewards commitment. Aston didn’t look like a team with much to commit with across the weekend. Over a single lap, the AMR26 was the slowest package in the field, and the race offered only marginal consolation: Alonso made the finish ahead of Valtteri Bottas’ Cadillac, but it wasn’t the sort of “best of the rest” scrap Aston Martin’s project is supposed to be about.
Honda, for its part, arrived encouraged that it had addressed battery vibration issues enough to make a clean race distance possible. In that sense the weekend ticked a box — the car did reach the flag. Stroll didn’t, but his retirement was down to a water pressure problem rather than the vibration topic that’s been hanging over the partnership since the opening rounds.
The vibrations are still there, though. Stroll’s verdict after Friday practice was short: “Still some work to do on that front.” And Honda has suggested the situation worsens when the power unit is installed in the AMR26, a detail that feeds back into Stroll’s point about shared responsibility. Integration matters. Packaging, mounting, cooling, how the car behaves over kerbs and at high speed — all of it can turn an engineering irritation into a persistent performance and reliability headache.
Aston Martin’s chief trackside officer Mike Krack had spoken ahead of the Japanese weekend about measures being put in place and tested at Suzuka. The trouble is that early-season F1 doesn’t allow much breathing room, and Stroll admitted as much when asked what comes next.
“Progress in F1 is never fast enough,” he said. “So right now, there’s no progress, because we’ve been in China and then straight to Japan, and we haven’t had much time to throw things at the car in terms of development. But we have a plan for the next few months, and what that brings in lap time, time will tell.”
That’s as close as you’ll get to a realistic status report in April: there’s a plan, but the calendar hasn’t allowed the team to execute it yet. Still, “plan” is a word teams reach for when the present is awkward. In a development race expected to be fierce and unpredictable under 2026’s new rules, the first few upgrades don’t just need to add lap time — they need to tell you your direction is right. Aston Martin’s bigger risk isn’t simply being slow now; it’s spending the next chunk of the season finding out the hard way that the core concept needs a rethink.
For Stroll, the psychology of it is different to the outside noise. There’s no benefit in performing public blame-games when the reality is tangled and the fixes require both factories pulling in the same direction. But there’s also nowhere to hide from what the timing screens are saying: Aston Martin is losing “huge amounts of time” where it’s most visible, and it isn’t sharp enough in the corners to disguise it.
The next few months, as Stroll put it, will tell. The stopwatch usually does.
