Honda has finally said the quiet part out loud: the stop-start nature of its Formula 1 programme has left a dent, and Aston Martin is the one discovering how painful that can be when the clock is already ticking toward Melbourne.
At Honda’s annual press conference in Tokyo, HRC president Koji Watanabe described a very real “period of inactivity” between the first shape of the 2026 power unit rules becoming clear and Honda having the people in place to attack them properly. In a regulatory reset year, that’s not a minor inconvenience — it’s the kind of lost time that never really comes back, because everyone else keeps moving.
Honda’s path to 2026 has been anything but linear. It had been supplying Red Bull when it chose to step away, only to be tempted back by the new engine formula and the chance to return as a full works operation, this time with Aston Martin. In theory, it’s a clean, glamorous marriage: an ambitious team with factory-scale resources at Silverstone and a manufacturer with recent championship pedigree.
In practice, the early evidence from pre-season testing has been a bit more raw.
Aston Martin managed just 400 laps across the Barcelona and Bahrain tests, and Bahrain in particular was heavily compromised by vibration issues that Honda is now working to resolve. The fix is due to be proven — or otherwise — at the season-opening Australian Grand Prix, which means Aston and Honda are heading into the first weekend of their new partnership with more unknowns than any front-running outfit would ever choose.
Watanabe didn’t dress it up. He explained that when Honda ended full works participation in 2021, engineers were moved back onto production and other company projects. Many left in March 2022. A small group remained to support Red Bull, but the broader engine development muscle simply wasn’t there at the exact moment the sport’s next ruleset was beginning to solidify.
“When the broad framework of the new regulations was finalised in 2022, we did not have the necessary personnel in place,” Watanabe said. “So in reality, there was a period of inactivity. The impact of that is, frankly, being felt.”
That timeline matters. In the early stages of a new power unit era, the big gains aren’t just about clever ideas — they’re about iteration speed. It’s about having enough experienced hands to run concepts through design loops, validation, manufacturing and test cycles without the whole machine stalling. If you’re late to that rhythm, you don’t just start behind; you spend your first months trying to build the orchestra while everyone else is already playing.
HRC managing director Ikuo Takeishi went a step further, linking the delayed start not only to the staffing gap but also to the cost cap constraints that applied once Honda’s return was approved in 2023.
“There was a real time lag in bringing people back,” Takeishi admitted. “And because of the cost cap, we were structurally behind. This timing issue, along with the cost-cap constraints, contributed to our delayed start. It’s something I reflect on.”
If that sounds like a corporate post-mortem, that’s because it is. But it also reads like a message aimed squarely at managing expectations — inside Honda, inside Aston Martin, and among a fanbase that remembers what happened last time Honda entered a new turbo-hybrid era without enough runway.
Everyone in the paddock still has those McLaren-Honda years somewhere in their peripheral vision. Bernie Collins, speaking on Sky F1, suggested the current Aston Martin-Honda situation is “definitely better” than McLaren’s first steps with Honda back in 2014. But she also relayed a brutal detail from the factory side: that when Honda first decided to pull out, it began stripping the operation back — leaving the return effort effectively restarting from an “empty factory”.
That context doesn’t absolve a difficult test, but it does explain why Honda is talking so candidly now. It knows exactly how quickly a narrative can take hold when an engine programme stumbles early, and it also knows what it takes to dig out of it.
Because Honda has lived both versions of this story.
The first turbo-hybrid project began in public pain — reliability and performance shortcomings that were impossible to hide. Yet, with time and direction, Honda turned itself into the benchmark power unit supplier of the previous cycle, ultimately powering six world championship wins once it linked up with Red Bull. The lesson is simple: Honda can get there. The problem is that “getting there” is usually not a one-winter process.
For Aston Martin, the timing is awkward. This is the year it needs momentum, not noise. A new works relationship is supposed to deliver clarity and a sense of forward motion. Instead, Melbourne is shaping up as a live systems test under race-weekend pressure, with the success of a vibration-related reliability fix potentially dictating the tone of the debut.
That’s a precarious place to be, because it doesn’t just affect Sunday. It affects everything: how much of Friday is usable, how aggressive you can be with mileage, whether you can explore set-up instead of simply surviving, and how quickly the whole operation can start learning in a new era.
And if you’re Aston Martin, learning is the point. The team hasn’t partnered with Honda to merely participate in 2026 — it has done it to give itself a legitimate route to the top. But works deals don’t guarantee a fast start. They guarantee responsibility, scrutiny, and nowhere to hide when the first problems show up.
Australia will tell us whether Bahrain was an early gremlin now exorcised, or the first sign of a tougher opening chapter. Either way, Honda’s message is clear: the comeback began later than it should have, and the sport is already collecting interest on that lost time.
