The Federation has yet to publicly announce the allocation of the ADUO bands, but the manufacturers already know where they stand. In Maranello, work on the power unit is already underway, and Ferrari’s championship fight has already entered a crucial phase.
One Grand Prix after the timeframe indicated for the announcement of the ADUO bands, one crucial element is still missing: an official FIA statement directed at the public. Transparency is what many within the Formula 1 community are calling for, yet it remains noticeably absent. This is not a minor issue or a secondary technical matter, because the system introduced to regulate power unit development is potentially one of the most influential tools available under the current Formula 1 regulations.
The way the ADUO mechanism functions could have a direct impact on the competitive order of the championship, influencing not only the manufacturers involved but also the balance of power across the entire grid. That is precisely why the absence of public communication has generated growing attention among fans, analysts, journalists, and paddock insiders alike.
The FIA knows, the teams know, the public does not: a transparency problem
The situation appears paradoxical and, in many ways, difficult to justify from a communication perspective. On one hand, reports suggest that at least three manufacturers have already received FIA approval to introduce the first update to their power units under the ADUO framework. On the other hand, there is still no public document clarifying which manufacturers have been placed in the recovery category and which have been excluded from it.
The result is a debate driven almost entirely by rumors, speculation, and competing interpretations. Three main scenarios are currently circulating throughout the paddock and among observers. The first possibility is that Mercedes has been granted ADUO status while Red Bull has not. The second is that both manufacturers have been excluded from the performance recovery category. The third is that Red Bull has been admitted while Mercedes has not.
All of these scenarios remain theoretically possible in the absence of an official announcement, which only fuels speculation and encourages further discussion. Every passing day without clarification increases uncertainty and creates room for additional theories regarding the actual competitive picture among the engine manufacturers.
The real anomaly, however, is not the speculation itself but the process behind it. According to information emerging from the paddock, the FIA has already distributed the relevant tables, calculations, and performance data to the manufacturers. The teams therefore know their position and are already acting accordingly. The only group left in the dark is the public, which continues to wait for official confirmation.
This inevitably raises questions about the transparency of the process, especially considering that the ADUO system was presented as a mechanism designed to balance performance and encourage technical convergence among engine manufacturers. The concept behind the regulation was relatively simple: prevent one supplier from enjoying an overwhelming advantage for an extended period while allowing those behind to recover some of the lost ground.
In such a context, full disclosure of the criteria, rankings, and allocation methodology would have seemed almost mandatory. Transparency would not only strengthen confidence in the system but would also help the wider Formula 1 audience understand how the regulatory framework is shaping the competitive landscape.
According to several reports and paddock reconstructions, one reason behind the lack of publication may be linked to objections raised by Red Bull regarding the FIA’s calculations and conclusions. If that is the case, the governing body may have chosen to delay public disclosure while addressing those internal concerns and reviewing any challenges that may have been submitted.
From a political standpoint, that decision might be understandable. The FIA may prefer to resolve disagreements before exposing sensitive information to public scrutiny. From a transparency standpoint, however, the situation is far less convincing. Formula 1 has spent years attempting to improve communication with its audience, and this type of uncertainty risks undermining that effort.
Ferrari and ADUO: an opportunity that cannot be wasted
Beyond the controversy, there is one aspect of particular interest to Ferrari. All available indications suggest that the Maranello-based team meets the requirements necessary to benefit from an ADUO allocation. If that is indeed the case, and all signs currently point in that direction, work on the Ferrari power unit has likely been underway for several weeks already. The engineers led by Enrico Gualtieri certainly do not wait for a press release before planning development work. Formula 1 operates according to strict timelines, and every day counts when championship ambitions are involved.
If the FIA has already communicated the technical details internally, Ferrari will know exactly how much development freedom is available and how best to exploit the opportunities provided by the regulations. Such information would allow the team to immediately begin evaluating performance targets, reliability considerations, and integration strategies for future upgrades.
It would therefore not be surprising to see a first, relatively modest evolution of Ferrari’s six-cylinder engine as early as the Austrian Grand Prix. Such an upgrade would not necessarily transform the competitive order overnight, but it could represent the first step in a development path intended to continue throughout the second half of the season. In modern Formula 1, gains are often achieved through a series of incremental improvements rather than a single revolutionary update. Even a small increase in efficiency, power delivery, energy recovery, or deployment performance can make a measurable difference over a race distance.
For Ferrari, ADUO is not merely a regulatory opportunity. It is a fundamental strategic tool that could influence the direction of the entire campaign. The 2026 Formula 1 season has so far been heavily shaped by Mercedes, which has secured six victories from the opening seven races. That level of success has established Mercedes as the benchmark against which every rival is measured.
The dominance displayed by the German manufacturer appeared to be supported not only by a highly effective chassis package but also by a significant power unit advantage. Throughout much of the season, the Mercedes package seemed capable of extracting superior performance across a wide variety of circuits and conditions.
However, the Spanish Grand Prix told a slightly different story. Lewis Hamilton’s victory demonstrated that the Ferrari SF-26 has become extremely competitive as a complete package. More importantly, the success achieved in Barcelona suggested that Ferrari’s aerodynamic and mechanical improvements are beginning to deliver the level of performance the team had targeted from the start of the season.
In Barcelona, the power deficit that had seemed more evident at other events appeared to have a much smaller impact on the overall outcome of the weekend. Ferrari looked competitive throughout the event, showing strong pace in conditions that had previously exposed some of its weaknesses.
That is a signal Ferrari will have analyzed very carefully. The significance of the Spanish Grand Prix extends beyond a single victory. It offered evidence that the SF-26 is capable of fighting at the front on merit and not merely through favorable circumstances. If the car has already shown it can beat what has been the benchmark team of the championship so far, then any gains delivered through engine development could become even more significant. In that scenario, ADUO would not simply help Ferrari close a gap. It could potentially help Ferrari create a genuine title challenge.
Ferrari’s objective is not simply to reduce a performance deficit. The goal is to transform an already competitive car into a complete championship-contending package capable of winning consistently across different types of circuits. From this perspective, access to ADUO could represent one of the defining moments of the season. It may become one of the key factors that determines whether Ferrari can sustain its challenge throughout the remainder of the championship and continue applying pressure to Mercedes.
The FIA must provide answers
There is, however, one final consideration that cannot be ignored. The FIA should publicly clarify what the manufacturers already know. A system this complex, built around coefficients, technical parameters, performance calculations, and differentiated development categories, requires communication that is clear, accessible, and transparent.
Without official information, the risk is that manufacturers continue working with certainty while fans, analysts, journalists, and observers are left navigating a landscape of assumptions and speculation. That situation benefits nobody and only creates unnecessary confusion around a topic that is already highly technical.
The credibility of the system depends not only on the quality of the calculations behind it but also on the willingness of the governing body to explain how those calculations are being applied. Formula 1 supporters increasingly demand transparency, and this is precisely the type of situation where greater openness would strengthen confidence in the process. Ferrari, meanwhile, cannot afford to wait. The championship battle is moving quickly, and development schedules do not pause while public announcements are delayed.
If the ADUO door is truly open, the team in Maranello has already walked through it. The engineers are almost certainly working on extracting every possible advantage from the opportunity in front of them, knowing that every improvement could prove decisive later in the season.
And if that is indeed the case, the first signs of progress may arrive much sooner than many expect—long before the FIA ultimately decides to publicly explain how the situation actually stands and which manufacturers have been granted access to one of the most important development tools in modern Formula 1.
