Ferrari will have two additional engine homologation opportunities for the 2027 Formula 1 season under the FIA’s ADUO regulations, but claims that the Scuderia could gain 10, 20 or even 30 horsepower remain entirely speculative. The governing body’s latest assessment has confirmed that Maranello will retain significant development flexibility as it attempts to close the performance gap to its rivals. However, the official concessions provide no reliable basis for calculating exactly how much additional power Ferrari might extract from its future engine.
The FIA’s latest communication concerning Additional Development and Upgrade Opportunities (ADUO), released this week, has not substantially changed the situation established by previous assessments. It has nevertheless confirmed an important advantage for Ferrari: the Italian manufacturer will have meaningful opportunities to improve its power unit during the final part of the 2026 development cycle and, more importantly, ahead of 2027.
FIA confirms Ferrari’s 2027 engine development opportunities under ADUO
According to the FIA’s communication, Audi, Ferrari and Honda have been placed in the category covering manufacturers with a performance deficit exceeding 4%.
This classification grants two additional engine homologation opportunities for 2026, both of which Ferrari has already used, along with another two for 2027. These concessions also include corresponding increases in permitted development expenditure and opportunities to conduct additional testing on the engine dynamometer.
The regulations are intended to provide manufacturers whose internal combustion engines are less competitive with additional opportunities to recover performance, rather than leaving them permanently restricted by the normal homologation framework.
The FIA’s latest ADUO assessment and Ferrari’s remaining engine deficit therefore represent an important development for the Maranello team’s longer-term technical programme. For Ferrari, these additional allowances offer a valuable opportunity, particularly when compared with the situation facing other Formula 1 power-unit manufacturers.
Mercedes received only one additional homologation opportunity for 2026, which the German manufacturer has not yet used, together with another opportunity for 2027. Red Bull, meanwhile, has received no additional concessions because its internal combustion engine was identified by the FIA as the performance benchmark.
This means Ferrari has more supplementary homologation opportunities than Mercedes and Red Bull under the current ADUO allocations. However, having greater regulatory freedom does not automatically mean the Italian manufacturer will achieve larger performance gains.
Why Ferrari’s two ADUO slots do not guarantee 10, 20 or 30 extra horsepower
These are the officially established and verifiable details. Since the FIA released its latest communication, however, speculation about the potential performance of Ferrari’s 2027 power unit has intensified.
Some projections suggest an increase of 10 horsepower. Others have proposed 20 horsepower, while more optimistic estimates have reached 30 horsepower. More cautious assessments suggest considerably smaller gains.
The problem with all these figures is that, at present, there is no concrete technical evidence allowing a specific horsepower increase to be attributed to Ferrari.
More importantly, the issue concerns the methodology used to produce these estimates. The two additional homologation opportunities granted to the Italian manufacturer do not correspond to any predetermined amount of power that can be recovered. There is no automatic conversion between the number of development opportunities assigned by the FIA and the performance improvement an engine manufacturer can achieve.
Two ADUO slots are regulatory opportunities, not a guarantee of a particular number of additional horsepower.
The effectiveness of an engine upgrade depends on several factors, including the areas selected for development, the starting performance level of the existing power unit, the quality of the technical solutions identified and the manufacturer’s ability to turn the additional regulatory freedom into a measurable improvement.
Why Ferrari’s 2027 engine gains will depend on technical development
Two engine manufacturers given the same number of homologation opportunities could achieve very different results.
A manufacturer starting from a more disadvantaged position might identify greater potential for improvement than a rival whose engine is already operating closer to its development potential. Equally, the effectiveness of the engineering work can produce substantial differences between the results achieved by different manufacturers, regardless of how many additional homologation opportunities they receive.
This is why associating Ferrari’s two 2027 ADUO opportunities with gains of 10, 20 or 30 horsepower currently means making assumptions without a verifiable technical foundation. The distinction is particularly important given the wider work under way on Ferrari’s planned 2027 power-unit redesign, which forms part of Maranello’s efforts to address the limitations identified during the 2026 season.
Ferrari has an opportunity to improve its engine, but the eventual benefit cannot be established simply by counting the additional development slots available.
Enrico Gualtieri and Ferrari already know where their 2027 engine must improve
Of course, the absence of reliable public estimates does not mean Ferrari is waiting to decide how to proceed.
On the contrary, it is reasonable to believe that the manufacturer’s engineers have already identified the areas requiring attention and that the development programme has been established for some time. A Formula 1 power-unit development strategy does not begin when the FIA publishes its latest regulatory assessment.
The technical department led by Enrico Gualtieri understands the strengths, weaknesses and potential development opportunities of Ferrari’s engine far better than any outside observer. Its engineers know which components and systems require attention, which compromises must be considered and which technical solutions could deliver the greatest performance benefit within the applicable regulations.
The team’s existing development programme and the relationship between Ferrari’s engine development schedule and financial restrictions provide further context for the challenge facing Maranello.
The availability of additional homologation opportunities is therefore one element of a wider technical process, rather than the starting point for Ferrari’s preparations.
Ferrari’s 2027 engine expectations must be separated from confirmed facts
The essential point is to distinguish what is known from what is merely being imagined.
Ferrari has two additional homologation opportunities available for 2027. That is the official position established by the FIA.
Whether those opportunities eventually produce an improvement of 10, 20, 30 or some other number of horsepower is an entirely different question, and one for which there is currently no definitive answer. The numerical projections circulating in recent days may encourage debate and generate expectations about the work taking place at Maranello. However, presenting hypothetical figures as established developments risks confusing technical reporting with the creation of expectations unsupported by evidence.
Ferrari has access to an important regulatory mechanism that could help it recover ground and improve its power unit ahead of the 2027 Formula 1 championship.
The Scuderia must now demonstrate that it can make effective use of those opportunities. Until the results of its development work can be established, any precise horsepower figure remains speculation.
