Ferrari has emerged as one of the main potential beneficiaries of the FIA’s latest Formula 1 engine development ruling, despite confirmation that its 2026 power unit remains behind those of Red Bull and Mercedes. The results of the third Additional Development and Upgrade Opportunities (ADUO) review period have preserved the Scuderia’s access to extra development allowances, creating an important opportunity for Lewis Hamilton and Charles Leclerc ahead of the 2027 championship.
Although Ferrari’s continued engine deficit represents a significant competitive disadvantage, the additional upgrade tokens could provide valuable flexibility as the Italian team prepares a major power unit overhaul for next season. With Red Bull currently setting the benchmark and Mercedes enjoying a stronger position than Ferrari, the regulations could help the Maranello manufacturer narrow the gap during the next phase of the technical development cycle.
FIA’s latest ADUO findings confirm Ferrari remains behind Red Bull and Mercedes
The FIA has completed the third ADUO assessment of the 2026 Formula 1 season, determining which power unit manufacturers qualify for additional development opportunities under the new regulations.
Introduced for the 2026 championship, the Additional Development and Upgrade Opportunities system is designed to assist manufacturers whose engines fall sufficiently far behind the strongest power unit. Rather than allowing an established advantage to remain unchallenged, the mechanism provides additional opportunities for those struggling with performance to introduce improvements.
Red Bull has been identified as the leading power unit manufacturer throughout the season, placing its rivals in a position to receive development allowances according to their respective performance deficits.
During the first two ADUO review periods, Ferrari was assessed as being more than four per cent behind the leading Red Bull power unit. That classification resulted in the Italian manufacturer receiving two upgrade tokens.
The third assessment has maintained the same situation. Ferrari remains behind both Red Bull and Mercedes, while its deficit continues to place the team in the category that qualifies for two additional development tokens.
At first glance, the findings appear disappointing for a manufacturer with Ferrari’s ambitions. The Scuderia has once again been classified among the weaker power unit suppliers, reinforcing the technical disadvantage that has affected its competitiveness during 2026.
However, the regulatory consequences could prove valuable as the team shifts its attention towards next season.
Why Ferrari’s engine deficit could become an advantage for 2027
The most important aspect of the latest FIA decision is not simply that Ferrari remains behind its rivals, but that its current classification provides additional opportunities to improve the power unit.
The extra ADUO tokens are expected to give the Maranello manufacturer greater flexibility to introduce developments towards the end of 2026 and during the following campaign.
Ferrari is already expected to undertake a substantial overhaul of its power unit for 2027. The additional development allowances could therefore complement those planned changes and provide further opportunities to refine the engine as the season progresses.
This represents an important distinction between Ferrari’s immediate competitive position and its development prospects. Being more than four per cent behind the benchmark is clearly undesirable, but the associated upgrade allowances could help the team address that weakness.
The situation also adds another dimension to Fred Vasseur’s previous acknowledgement of Ferrari’s longstanding engine deficit, which has raised questions about the decisions taken during the development of the current power unit.
According to reports, Ferrari’s engine is also weaker than Audi’s, although both manufacturers fall within the same ADUO category, more than four per cent behind the leading power unit.
That comparison underlines the scale of the challenge facing the Italian manufacturer. Nevertheless, the ADUO system provides a mechanism through which Ferrari can pursue additional improvements rather than relying exclusively on the development opportunities available to its strongest competitors.
Lewis Hamilton and Charles Leclerc could benefit from extra Ferrari engine upgrades
The latest ruling is particularly relevant to Lewis Hamilton and Charles Leclerc, who have both repeatedly called for Ferrari to address the weaknesses of its 2026 power unit.
Engine performance has become one of the team’s principal technical priorities as preparations intensify for the 2027 championship. Although improvements introduced during the current season have helped in other areas, the power unit remains a major obstacle to Ferrari’s ambitions.
For Hamilton, the opportunity to benefit from additional engine development is especially important as the seven-time world champion continues to push for a competitive package capable of challenging for the title.
Leclerc shares that objective, with both drivers seeking improvements that would allow Ferrari to compete more effectively against its leading rivals.
The Italian team’s development programme is expected to focus heavily on addressing its existing disadvantages, and the additional ADUO allowances provide another opportunity to introduce changes beyond the initial 2027 specification.

Ferrari gains development flexibility while Red Bull and Mercedes face tighter allowances
The first ADUO review period of the 2027 Formula 1 season will cover the opening six Grands Prix, making the initial phase of the championship particularly important for manufacturers seeking to improve their engines.
Under the current assessment, Red Bull’s superior power unit performance means the manufacturer will not receive additional upgrade tokens at the beginning of the year.
Mercedes, meanwhile, has been allocated one token, placing the manufacturer between Red Bull and Ferrari in terms of the extra development opportunities available.
Ferrari’s allocation of two tokens therefore gives the Italian manufacturer greater regulatory flexibility than either of those rivals.
That advantage could become significant if the team makes progress with its planned engine overhaul and then uses the additional allowances to introduce further refinements during 2027.
The situation does not change the fact that Red Bull currently holds the strongest position in terms of power unit performance. However, it means Ferrari has access to development opportunities that are not available to the leading manufacturer under the same conditions.
For a team attempting to recover from a substantial engine deficit, that distinction could be important in determining how quickly it closes the gap.
Honda and Aston Martin also benefit from FIA engine development allowances
Ferrari is not the only manufacturer-related operation with reason to welcome the latest ADUO classification.
Aston Martin and its power unit partner Honda remain in the lowest performance category, meaning they also qualify for additional development opportunities.
Honda’s difficulties have been sufficiently severe during 2026 that rival teams provided extra assistance earlier in the season to help the Japanese manufacturer address its disadvantage.
Nevertheless, there are encouraging indications that Honda could improve its competitive position for 2027. Like Ferrari, the manufacturer will have access to additional upgrade tokens as it attempts to strengthen its power unit for the new championship.
That prospect is particularly encouraging for Fernando Alonso, who stands to benefit if Aston Martin and Honda make meaningful progress with their engine package.
The FIA’s latest assessment therefore creates opportunities for two manufacturers currently struggling to match the strongest power units, even though their immediate performance disadvantages remain substantial.
Can Ferrari turn its ADUO advantage into a championship challenge?
For Ferrari, the key question is whether the additional development opportunities can translate into a meaningful reduction in its engine deficit.
The latest ADUO findings confirm that the Scuderia still has considerable ground to recover against Red Bull and Mercedes. However, the regulations also provide a route through which the Italian team can introduce additional improvements as it prepares for 2027.
The combination of a planned power unit overhaul and extra upgrade allowances offers greater flexibility than Ferrari’s leading rivals currently possess under the ADUO system.
That opportunity could become particularly valuable during the opening six races of next season, when the first review period will determine how manufacturers are assessed under the new championship conditions.
For Lewis Hamilton and Charles Leclerc, the development allowances represent a potentially important step towards obtaining the performance they have been requesting throughout 2026.
Ferrari still faces the challenge of converting those regulatory opportunities into effective technical improvements, but the latest FIA ruling gives the Maranello team additional tools to pursue its ambition of returning to the front of Formula 1 in 2027.
