Fórmula 1 will have an important structural change in the days following Grande Prêmio of Canadá, scheduled for Sunday, May 24th. Federação Internacional of Automobilismo will introduce the first application window of ADUO, an acronym in English for Oportunidades Adicionais of Desenvolvimento and Atualização. The system aims to grant technical concessions to engine manufacturers that present a performance disadvantage of more than 2% in relation to the best-rated power unit in the championship. The regulatory entity’s objective is to balance the grid’s forces after the implementation of the category’s new engine regulations.
The federation’s initial estimate was that monitoring would begin shortly after the fifth stage of the season, in Miami. Contudo, the cancellations of the Bahrein and Arábia Saudita stages changed the original schedule of the world championship. Diante of changes to the competition calendar, the entity revised the sampling periods to complete the performance reports of the five current manufacturers.
Federation monitoring Calendário divides the championship into three evaluation blocks
The federation’s technical council has established three specific windows throughout the 2026 season to analyze data from internal combustion units. The first period comprises the first five races of the year, starting from Grande Prêmio and Austrália until the end of the race in Montreal, in Canadá.
The second block of analyzes will cover the sixth to the eleventh stage of the season, covering the interval between Grande Prêmio of Mônaco and Grande Prêmio of Hungria. Finally, the third stage of capturing statistical data will occur from the twelfth to the eighteenth race, comprising the disputes from Holanda to México. The consolidated data from each block serves to decree which brands receive immediate improvement rights.
Automakers that meet the regulatory technical delay requirements will be able to apply the permitted modifications from the test following the entity’s official announcement. In the specific case of this first evaluation cycle, the brands approved for the recovery package will introduce the revised components in Grande Prêmio and Mônaco, scheduled for June 7th. The performance index exclusively considers the efficiency of the internal combustion engine, isolating energy delivery data from batteries and associated electrical systems.
Entidade changes rules to increase testing volume and readjust budget ceiling for registrants
The federation made changes to regulatory guidelines earlier this month with the aim of expanding the aid ranges for scenarios of extreme income disparity. The main change consisted of the creation of an unprecedented category aimed at manufacturers that record a deficit of more than 10% compared to the leader in the performance ranking. The projection of paddock engineers indicates that the Honda, exclusive supplier of the Aston Martin, should fit into this last technical tolerance band.
Manufacturers that present consolidated disadvantages will receive express authorization to exceed the standard limits of development hours on dynamometers and test benches. The gain in working time accompanies a proportional flexibility in the annual spending ceilings stipulated by the category. Atualmente, five industrial groups operate in the championship to supply the eleven teams that make up the current Fórmula 1 grid.
- Mercedes: operates with its own team and distributes engines for McLaren, Alpine and Williams.
- Ferrari: equips the factory team’s cars and sells units to Haas and Cadillac.
- Ford: Provides the propulsion technology for the Red Bull and Racing Bulls cars.
- Audi: works in a fully integrated format with a chassis and engine developed in-house.
- Honda: works dedicatedly to supply power blocks to the Aston Martin.
Technical compensation Escala distributes overtime on benches according to power deficit
The research time distribution criteria were scaled into six competitive bands by the federation’s technical management. Marcas with a disadvantage of less than 2% do not receive compensation and maintain the basic development schedule without the right to extra updates in the current season.
Para For manufacturers who register a performance delay of between 2% and 4%, the regulation passes on a bonus of 70 hours of additional testing, in addition to guaranteeing an extra update in 2026 and another in 2027. Engines that fall within the range of 4% to 6% disadvantage guarantee 110 extra dynamometer hours and two allowed updates. The 6% to 8% range grants 150 hours of testing, while the 8% to 10% range yields 190 hours for the affected brand’s engineering plan.
At the top of the aid table, automakers with losses above 10% gain the right to use 230 extra hours of technological development at their headquarters. The modification rights granted by the technical council are cumulative between the years of validity of the current regulation. Isso means that a manufacturer with severe problems can accumulate evolution packages if it does not close the gap to direct competition in the next cycle.
Mudança of forces can reposition Ferrari and Audi in the main platoon of the category
The start of the ADUO system seals raises expectations about changes in the dynamic behavior of traditional team cars. Red Bull must not reach the necessary rates to receive incentives governed by the federation, being prevented from making structural changes to its blocks provided by Ford. On the other hand, Ferrari and Audi emerge as the main candidates for receiving overtime work packages.
The Italian team faces problems with final speed on the long straights of world circuits, but has one of the best acceleration responses when exiting low-speed curves. Esse behavior is due to the compact design of the turbocharger assembly adopted by the Maranello engineers for this championship. Releasing focused upgrades can resolve aerodynamic drag and lack of bottom-end power, making the car competitive on high-speed tracks. If the brand makes significant progress before the race on the streets of Monte Carlo, the dynamics of the classification could give the red team a chance of victory.
