Honda handed extra development budget after new ADUO target
Honda Granted Financial Relief Under Revised ADUO Framework
Honda have been awarded an increased budget allowance to accelerate the development of their 2026 Formula 1 power unit, following the introduction of a new tier within the sport's ADUO — Additional Development and Upgrade Opportunities — framework.
The system was established ahead of the 2026 season specifically to prevent large, sustained performance disparities between engine manufacturers. In its original form, it operated on two tiers: manufacturers found to be more than two percent off the benchmark power unit received concessions, while those more than four percent adrift were entitled to a greater level of support.
But a new, third tier has now been added — targeting manufacturers more than 10 percent off the pace. Few in the paddock doubt who this measure is designed to help. Pre-season estimates placed Honda more than 80 horsepower behind Mercedes, widely regarded as the benchmark supplier heading into the new regulations, with Red Bull understood to be the second reference point.
The Scale of Honda's Challenge
Given that Honda have reportedly prioritised reliability over outright performance in their development programme to this point, there is little expectation that they have closed that gap significantly since pre-season. The budget cap increase granted through ADUO represents a meaningful injection of resources, though the scale of the deficit means the challenge remains formidable.
The situation at Aston Martin — Honda's sole works-aligned customer team — has been well documented. Fernando Alonso has spoken of needing meaningful upgrades around the summer break as the team searches for performance in a difficult opening phase of the campaign.
Newey's Calculated Candour
At the centre of the narrative surrounding Honda's struggles is Aston Martin's new technical figurehead, Adrian Newey. In a press conference ahead of the season-opening Australian Grand Prix, Newey delivered a strikingly candid assessment of the team's predicament — describing the battery situation as "scary" and revealing that vibrations from the power unit were so severe that drivers risked nerve damage after a certain number of continuous laps.
Such transparency is unusual in Formula 1, where technical weaknesses are typically kept firmly behind closed doors. Some within Aston Martin reportedly felt Newey had gone too far. But others in the paddock have drawn a more calculated conclusion: that the remarks were deliberately designed to apply pressure on the sport's rulemakers.
The suspicion is that Newey, aware that the existing two-tier ADUO structure was insufficient to address Honda's deficit, used his rare platform in front of the media to shape the narrative and force the hand of those responsible for the regulations. Whether or not that was the intention, the outcome — a new tier of support aimed squarely at manufacturers in Honda's position — appears to have delivered exactly what Aston Martin needed.
For a man who so rarely speaks to the press, the timing and content of Newey's comments have proven remarkably effective.
