HRC president Koji Watanabe says Honda’s latest F1 power unit update meets power goals but worsens driveability, echoing early Spec 1 behavior, after mid-season deployment on Aston Martin’s AMR26.

The package still trails rivals on output, and the car’s behavior remains inconsistent, with reports of turbo lag and erratic downshifts undermining confidence and corner entry stability.

Under current rules, energy management is pivotal, with roughly half the lap energy from electrification. That amplifies how combustion response, deployment strategy, and harvesting interact with chassis characteristics.

The update arrived via the Additional Development and Upgrade Opportunities program, targeting the power gap. Honda met its Spec 2 power aim, but combustion changes degraded throttle mapping and smoothness.

Watanabe concedes driveability regressed toward early Spec 1 levels. Honda continues hardware revisions and software refinement, yet acknowledges outright power remains a decisive competitive weakness.

Aston Martin’s recent form stabilizes somewhat. Six points across the last six races reflect incremental gains, but drivers still call for stronger deployment, cleaner downshifts, and more responsive torque delivery.

Honda’s timeline explains much of the deficit. After ending its Red Bull partnership in 2021, HRC restarted late, rebuilt staffing, and initially prioritized battery and motor systems over combustion progress.

By 2023, Honda estimates it is almost two years behind. Catch-up work then meets budget caps and limited operating hours, restricting dyno running and on-site integration with the team.

The task now is balance. Combustion efficiency, turbo response, and hybrid deployment must align, so energy harvesting and delivery support corner phases without spiking wheelspin or unsettling the rear.

ADUO allowances offer narrow windows, making calibration choices critical. Honda must turn dyno gains into track consistency within the ADUO framework in F1, where scope is tightly policed.

Watanabe targets parallel gains in output and control, promising further hardware tweaks and control software overhauls. Coordinated chassis integration at Aston Martin will be vital to translate lab steps.

The trajectory remains upward but uneven. Competitive midfield targets depend on restoring driveability while closing the power gap, with lessons also informing Red Bull ADUO talks across the paddock.
