Honda F1 2026 Power Unit Upgrade: Real Progress, Driveability Challenges, and the 2026 Game

Zandvoort, August 2026. In the closed press room of the Paddock, Yasuo Orihara — Honda's technical director for the F1 project — placed a blank sheet of paper on the table. No numbers. No charts. Just a blank space sufficient to say everything. When journalists asked about engine horsepower after the first upgrade of the season was fitted to the Aston Martin AMR24 at Zandvoort, Orihara simply pointed to that paper as a way of saying "we are not disclosing." Ten days later, at Monza, he returned with a joke about that piece of paper — but this time, accompanied by a more serious message: the engine had made progress on performance, but the issue lay in how it responded to the throttle.

That was the beginning of a story I have witnessed repeat itself over four decades of following F1: when an engine manufacturer acknowledges driveability problems, that is not a sign of weakness — it is a sign of maturity. And this story has more layers than the surface reveals.

Technical Context: Engines Frozen, But Not Everything Frozen

Since the 2026 season, the power unit freeze regulations have transformed F1 into an entirely different chessboard. Manufacturers can no longer change hardware to improve performance at will — they are only permitted to refine reliability and driveability, meaning how the engine responds to driver inputs. This is a regulatory framework requiring technical finesse at a completely different level than the previous "arms race" era.

Honda's first upgrade of the 2026 season — fitted to the cars at the Zandvoort round — was entirely focused on the internal combustion engine (ICE). There were no changes to the ERS, MGU-H, MGU-K, or battery systems. This was a strategic decision aligned with current regulations: when hardware is frozen, all improvements must go through mapping, data settings, and control tools.

Orihara confirmed that Honda had "confirmed what they saw on the dyno" in absolute performance. This is an important statement: it shows Honda's development tools have high reliability in predicting absolute performance. But — and this is the key point — it does not confirm that everything from the dyno transfers perfectly to the race track.

Tactical Analysis: Driveability Is Not a Word — It Is a System

When Mike Krack, Aston Martin's team principal, said driveability is "also a chassis topic," he was not overstating. In modern F1, driveability encompasses at least four dimensions: shifting quality, combustion stability during braking, engine braking, and torque pickup. Each of these dimensions interacts with other car systems — brakes, aerodynamics, chassis balance — creating a multi-dimensional optimization problem that cannot be solved in a single laboratory.

At Zandvoort, where banking corners require heavy braking into low-speed turns, these issues were clearly exposed. Fernando Alonso — a driver with a late-braking, attacking style — was the first to feel the difference. Lance Stroll, with a more conservative driving approach, might be less sensitive, but feedback from both was sent back to Honda's HRC Sakura development center for analysis.

This is the point I see many people overlook: driver feedback is not soft data. In 41 years of following F1, I have witnessed cases where subjective driver feedback led to transformative changes that objective data could not detect. Alonso, with hundreds of Grand Prix behind him, can describe throttle response differences at a level of detail no sensor can replace.

Honda developed countermeasures at HRC Sakura within 10 days — from Zandvoort to Monza. This is an impressive speed, showing the advantage of calibration-based development over hardware changes. But will Monza — with its high-speed, low-downforce characteristics — be a representative test for these countermeasures?

Contrarian View: The Real Problem Is Not the Engine

There is something I commonly see in F1 analysis: people focus too much on the engine as an isolated entity. But in modern F1, nothing is isolated. Honda's engine is not just a horsepower-producing machine — it is part of a system including brakes, aerodynamics, and especially the chassis. And here, there is a factor I think is being underestimated: Adrian Newey.

Newey joined Aston Martin with the reputation of one of the greatest designers in F1 history. His first major upgrade package was introduced in Hungary, before Honda's engine upgrade appeared at Zandvoort. This is not a coincidence — it is a coordinated development plan. But when the chassis changes, it changes how the engine interacts with the car.

Krack said driveability is "also a chassis issue" — I believe he is telling the truth, but perhaps he is also distributing responsibility. This is something I have seen in many works partnerships: when there is a problem, both sides have incentives to avoid taking all the blame. But that does not mean the problem does not exist — it only means the solution is more complex than a single engine issue.

Another detail I find noteworthy: Orihara bringing the blank piece of paper to Zandvoort was not just theater — it was a signal. If the upgrade truly delivered a major leap, why not announce the numbers? The answer might be here: the raw performance benefit may be modest — perhaps in the range of 5-10 horsepower — rather than a significant step.

Competitive Analysis: The Real Game Is 2026

In the broader picture, the 2026 season is merely a prelude to the major change in 2026, when new engine regulations with higher electrification and sustainable fuels will take effect. Honda has strategically bet on Aston Martin as a works partner from 2026 — a significant commitment from a manufacturer that withdrew from F1 in 2026 before returning as a supplier to Red Bull Racing.

Current driveability work, while important for the 2026 season, has greater strategic significance: it is training Honda's team in lessons about combustion stability and control calibration that will directly transfer to the 2026 engine architecture. This is a long-term investment disguised as an ongoing season issue.

In the midfield battle — where qualifying gaps are often measured in hundredths of a second — driveability can be the difference between a strong and a weak race start, or between consistent and inconsistent lap times. Aston Martin is in the middle of that battle, with support from an engine partner learning to work with Newey's new chassis.

Questions to Monitor: Monza Is Not Everything

The Monza round is positioned as the validation point for driveability countermeasures. But I question: is Monza the right test? Monza's characteristics — high speed, little heavy braking, few low-speed corners — may not be representative conditions for the issues found at Zandvoort. If driveability truly is a problem at low-speed banking corners, then Singapore or Mexico — with their tight corners and heavy braking — are the real tests.

What I will monitor in the coming rounds: Alonso's feedback on throttle response and braking stability, Aston Martin's lap time consistency compared to other midfield rivals, and whether Krack continues to emphasize the "shared" nature of the issue or begins to differentiate the framing.

Conclusion: The Maturation of a Relationship

Honda faces a driveability challenge in the 2026 season, but how they are responding — with speed, transparency, and willingness to learn from driver feedback — shows an engine manufacturer maturing in its works partner role. Lessons from these issues will not only improve the AMR24 in the short term — they will shape how Honda approaches the 2026 engine, when the real game begins.

For Aston Martin, the question is not whether they can solve the driveability problem — I believe they can — but whether they can solve it fast enough to maintain their midfield position while still preparing for the bigger leap in 2026. That is a resource balancing equation not every team can solve.

But ultimately, in a sport where every collapse has a precursor and every advance is built from small failures, these may be the "good" problems to have — because they are being solved before they become bigger ones. And that, in my 41 years of experience, is always a sign of an organization that knows how to learn.
