Koji Watanabe doesn’t mind a hard conversation. In fact, with Adrian Newey now at Aston Martin and Honda’s 2026 power unit taking shape, he says the best ones get a little fiery.
The Honda Racing Corporation president lifted the lid on how the partnership with Newey is bedding in ahead of F1’s next rules reset — and it sounds exactly like you’d expect from two serial winners reunited on the same side of the table.
“We laughed a lot in the first meeting… it was very much: ‘Well, here we are again!’” Watanabe said of his first sit-down with Newey at Silverstone. The pleasantries don’t last long, though. “I communicate with him frequently and it’s often a quite intense exchange of opinions, suggestions and feedback — but always with the focus on winning.”
Newey is now the heartbeat of Aston Martin’s 2026 project, running the AMR26 build and — crucially — stepping up to team principal next season. That move triggers a strategic reshuffle: Andy Cowell shifts to chief strategy officer to shepherd the three-way alignment between Aston Martin, Honda and Aramco. It’s a clear tell of how Lawrence Stroll wants this era to be run: a laser-focused technical boss with carte blanche, backed by a heavyweight operator keeping the alliances tidy and the dollars pointed in the right direction.
For Watanabe, the interface is where the magic — and the tension — lives. Honda’s hybrid unit and Newey’s chassis have to be designed around each other, especially under 2026 regulations that place even more emphasis on energy management, packaging and weight. That’s Newey’s playground. It’s also where the arguments start.
“It can be about anything,” Watanabe said. “A very detailed design issue… competitor analysis… how to manage people to get the best out of them, or even finance and using the limitations of the cost cap most effectively.”
If that tone feels familiar, it should. When Newey worked with Honda power at Red Bull from 2019 to 2024, the collaboration powered Max Verstappen’s four straight titles from 2021 and two constructors’ crowns along the way. The blueprint wasn’t just about raw horsepower or slippery aero; it was about locking the two together early and never compromising late.
That ethos is already showing at Aston Martin. Newey has hinted the 2026 rulebook — much like the 2022 ground-effect reboot — is more pliable than it first appears. “More flexibility for innovation,” was how he put it earlier this year, which set off the usual paddock radar. Damon Hill couldn’t resist the nudge: “He’s found something.”
Whether there’s a bona fide loophole in play or not, the timing matters. Aston Martin plans to roll out the AMR26 on February 9 — intriguingly, 10 days after the closed-door opening test at Barcelona. Teams have been asked to run temporary liveries for that one, with full race colours expected to break cover at the second test in Bahrain from February 11–13. Bahrain will also host the final pre-season running on February 18–20 before the season opens in Australia on March 8.
It’s an unusual cadence and a small advantage for the organised. If you’re confident enough in your early direction to hide your hand in Barcelona, then arrive in Bahrain with a fully dressed race car and systems synced, you save energy and you save noise. That’s typically Newey’s way: get the concept right, don’t chase every headline, arrive ready.
The relationship dynamic will be fascinating. Newey is famously uncompromising on packaging; Honda’s programme, by necessity, needs a clear timetable. When those meet, it often means tricky decisions: where to carry weight, how to cool the battery, how aggressive to be with split turbo placement and ancillaries, how to balance the FIA’s energy flow constraints with the car’s aerodynamic center of pressure. That’s where the “intense exchanges” live — and honestly, that’s what good looks like at this level.
There’s also the wider mood music. Aston Martin’s 2025 campaign has offered flashes and frustration in equal measure, but 2026 is the clean slate the project has been pointed toward since the Honda deal was announced. With Newey now formally in charge of the whole thing — not just the drawing board — the accountability lines are simple. If the AMR26 is quick out of the box, Aston Martin enters a new chapter. If it’s not, there’s nowhere to hide.
Watanabe doesn’t sound worried. He sounds engaged. And that matters, because Honda’s return as a full works partner is a pride play as much as a sporting one. The brand likes winning on merit and on message. A Newey-led Aston Martin gives them a platform to do both — as long as those “intense” talks end with the right compromises.
In the end, that first meeting probably told the tale. Two old collaborators having a laugh — then getting straight back to the hard stuff. For 2026, that’s exactly the energy Aston Martin needs.
