Ferrari Targets Engine Gains via ADUO
Ferrari has identified the need for upgrades to its ADUO system to achieve meaningful performance improvements with its power unit during the 2026 season. The Scuderia views enhanced development in this area as essential for closing the competitive gap in the current campaign.
Ferrari's Power Unit Development Priorities
The Scuderia faces a crucial juncture in its 2026 power unit development strategy. Team officials have publicly acknowledged that meaningful performance gains will require dedicated attention to the ADUO system, signaling a focused technical direction for the remainder of the season. This assessment reflects the high-stakes nature of contemporary Formula 1 engine development, where incremental improvements across multiple systems can translate into decisive advantages on track.
Understanding the ADUO System
The ADUO component represents a critical element within modern Formula 1 power units. As engines have become increasingly sophisticated and regulated, manufacturers have concentrated development efforts across multiple integrated systems working in concert. The identification of the ADUO as a primary upgrade target demonstrates Ferrari's methodical approach to competitive improvement, pinpointing specific areas where engineering gains are both achievable and impactful.
Technical development in Formula 1 power units operates within strict regulatory parameters that define both performance capabilities and cost controls. Within these constraints, teams must prioritize their development roadmaps strategically, focusing resources on systems offering the highest return on investment. Ferrari's decision to emphasize ADUO upgrades reflects an engineering assessment that this particular area holds significant untapped potential for the Scuderia's competitive position.
The Path Forward
For Ferrari to achieve the "clear improvement" referenced in technical discussions, the ADUO upgrade program must progress according to schedule throughout the 2026 season. This developmental timeline underscores the iterative nature of modern power unit evolution, where teams continuously introduce refined specifications and enhanced components as engineering solutions are validated and manufactured.
The competitive landscape of 2026 demands that engine manufacturers balance immediate performance needs with longer-term strategic planning. Ferrari's commitment to ADUO development exemplifies this dual focus, addressing current performance requirements while establishing foundations for future competitiveness.
Sunday's Racing Intelligence
This assessment emerged from Sunday's detailed analysis of ongoing technical developments across the Formula 1 grid. The RaceFans round-up brought together key updates from multiple fronts within the sport, with Ferrari's power unit strategy representing one of several significant storylines shaping the 2026 season narrative.
Such technical revelations provide crucial insight into how teams approach the complex challenge of performance optimization within Formula 1's highly regulated environment. Engine development programs operate on multi-year timescales, yet individual season updates can prove decisive in determining competitive outcomes on the circuit.

Article 4.3
ADUO Operational and Financial Measures and Eligibility Criteria
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
This rule gives struggling power unit manufacturers extra development opportunities to catch up. If a manufacturer's engine is 2-4% slower than the best engine, they get 1 extra upgrade per season for two seasons. If they're 4% or more behind, they get 2 extra upgrades per season instead. These upgrades are one-time grants and don't stack within the same season.
- ADUO (Aid to Disadvantaged Users of Older power units) provides extra homologation upgrades for manufacturers falling behind on performance
- Eligibility is based on ICE Performance Index: 2-4% gap = 1 upgrade per season; 4%+ gap = 2 upgrades per season
- Upgrades are granted for two consecutive seasons (N and N+1) but don't accumulate within a single season
- Manufacturers must also reduce their Cost Cap spending downward when receiving these benefits
Official FIA Text
At the end of each of the ADUO periods specified above, every PU Manufacturer granted ADUO may implement further upgrades to their homologated Power Unit (as described in Article 3.3 of this Appendix), extend the usage of their Power Unit Test Benches for Restricted Testing (as described in Article F5.2.7) and must make a downward adjustment for Cost Cap purposes (pursuant to Article 4.1(t) of the Power Unit Financial Regulations). a. PU Manufacturers whose ICE Performance Index is at least 2% but less than 4% below the best-performing ICE will be eligible for: i 1 additional homologation upgrade in season N ii 1 additional homologation upgrade in season N+1 b. PU Manufacturers whose ICE Performance Index is at least 4% below the best-performing ICE will be eligible for: i 2 additional homologation upgrades in season N ii 2 additional homologation upgrades in season N+1 ADUO homologation upgrades are not cumulative within a season and will only be granted following the first occasion that the PU Manufacturer is assessed by the FIA as eligible for ADUO according to the criteria in this Article. [The proposed 2% threshold and subsequent resolution of the ICE performance index will be validated or adjusted after conclusion of the ongoing activities between PU Manufacturers and F1 Teams related to the on-track ICE performance measurement]
Article 4.4
Application of ADUO homologations
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
Power unit manufacturers can use engine upgrades (called ADUO homologations) that they've been granted in the current season, plus any upgrades they were approved for from the previous season. If they don't use an upgrade by the final race of the season, they lose it. Teams that don't get approved for upgrades in the first two review periods of the season can't try again in the final period.
- Manufacturers receive a limited number of engine upgrade slots per season based on performance-based grants
- Upgrades approved in the previous season carry over and stack with current season allowances
- Unused upgrades must be introduced by the final race or are forfeited permanently
- Missing upgrade approval in the first two periods disqualifies a manufacturer from the third period window
Official FIA Text
a. If a PU Manufacturer receives an ADUO grant for one or two ADUO homologation(s) upgrade(s) in season N, only the corresponding number of one or two ADUO homologation(s) is(are) permitted in that season in addition to any ADUO homologation(s) granted in season N-1 and applicable to season N. b. Any ADUO homologations awarded in season N-1 for use in season N will be in addition to those which may be granted in Season N. c. Any unused ADUO homologation upgrade awarded in season N for use in season N, if not introduced by the final Competition of the season, are forfeited. d. PU Manufacturers not granted ADUO following either of the first two ADUO Periods of season N are not eligible for ADUO in the last period of that season (as described in Article 4.2 of this Appendix). The FIA reserves the right to implement corrective actions, at its sole discretion, should the upgrades implemented under Article 3.3 result in a competitive imbalance. Any such actions will be discussed in good faith with all PU Manufacturers
Article 2.2
2026 Power Unit Regulations
Chapter: Chapter II - Power Unit Changes
In Simple Terms
2026 brings major engine rule changes. The complex MGU-H is removed to cut costs and attract new manufacturers. To compensate, the MGU-K becomes much more powerful and the battery is bigger. The goal is simpler, more sustainable power units that are still cutting-edge.
- MGU-H removed from power units
- MGU-K power increased significantly
- Larger energy store capacity
- Aims to attract new manufacturers
Official FIA Text
For 2026, the power unit will comprise a 1.6 litre V6 turbocharged internal combustion engine with a significantly enhanced electrical component. The MGU-H will be removed. The electrical power output will increase substantially with a more powerful MGU-K and larger energy store.
