Ferrari could be preparing one of the most important technical offensives of its 2026 Formula 1 campaign as the Scuderia awaits a crucial FIA decision regarding ADUO development concessions. With growing confidence that the team may qualify for additional engine development opportunities, Maranello is reportedly finalizing a two-step power unit upgrade strategy aimed at reducing the performance deficit to Mercedes.
Although the SF-26 has impressed with its aerodynamic efficiency, chassis balance and cornering performance, one area continues to attract attention inside Ferrari: outright engine power. Throughout the opening phase of the season, Lewis Hamilton and Charles Leclerc have frequently found themselves at a disadvantage on circuits where straight-line speed and power unit performance play a decisive role.
As a result, Ferrari’s technical department has been closely monitoring the FIA’s ADUO evaluation process, which could provide the team with a valuable opportunity to accelerate development and recover lost ground against its rivals.
ADUO could unlock additional Ferrari engine development
The FIA has spent recent months collecting and analyzing power unit data from all Formula 1 manufacturers in order to determine which suppliers may qualify for development concessions under the ADUO framework.
The system was specifically designed to prevent engine performance disparities from becoming too large by allowing manufacturers that fall behind the benchmark to introduce corrective upgrades during the homologation cycle.
Current expectations suggest that manufacturers found to be between two and four percent behind the reference power unit would be granted a single development step. Those exceeding a four-percent deficit could potentially receive authorization for two separate upgrade packages.
According to paddock speculation, Ferrari believes its current situation could place it in the second category, opening the door to a more aggressive development program than initially anticipated.
For a team determined to return to the front of Formula 1, such a decision could have major consequences for the remainder of the season and beyond.
First upgrade may arrive earlier than expected
Reports emerging from France suggest Ferrari is already preparing to accelerate its timetable.
According to information circulating within the paddock, the first ADUO-related power unit evolution could arrive at the Austrian Grand Prix rather than later in the season as originally expected. Such a move would underline the urgency Ferrari places on improving straight-line performance and reducing the gap to Mercedes as quickly as possible.
The Austrian circuit, with its long acceleration zones and power-sensitive layout, would provide an ideal environment to evaluate the effectiveness of any engine-related gains. For Lewis Hamilton and Charles Leclerc, even a modest increase in available power could significantly improve race performance, qualifying pace and overtaking opportunities against direct rivals.
A second evolution planned for the second half of the season
Ferrari’s strategy reportedly extends beyond a single upgrade package. Several sources indicate that a second and more comprehensive power unit evolution is being prepared for introduction after the summer break.
The Dutch Grand Prix at Zandvoort has emerged as the most likely target for this second phase of development. Introducing the upgrade there would also allow Ferrari to fine-tune the package ahead of the Italian Grand Prix at Monza, a circuit where engine performance traditionally becomes one of the most important competitive factors.
By splitting the development program into two stages, Ferrari hopes to progressively reduce the deficit rather than waiting for a single large update later in the year.
Internal projections reportedly suggest the first package could eliminate a substantial portion of the gap to Mercedes, while the second evolution would deliver additional gains and bring the power unit closer to the benchmark level.
Why reliability remains a critical factor
While performance gains are the primary objective, Ferrari must also balance development with reliability. Formula 1’s modern power units are among the most complex engineering systems in motorsport, and any increase in performance must be validated through extensive dyno testing and simulation work.
This explains why the second stage of Ferrari’s development plan would require additional preparation time. Engineers in Maranello are expected to conduct extensive bench testing before introducing further modifications to ensure the upgrades deliver both performance and durability.
The team is determined to avoid sacrificing reliability in pursuit of short-term gains, particularly during a season where every championship point could prove decisive.
Lewis Hamilton and Charles Leclerc could be major beneficiaries
If Ferrari receives FIA approval for the full ADUO development program, Lewis Hamilton and Charles Leclerc could soon have a significantly stronger package at their disposal.
The SF-26 has already demonstrated that it possesses one of the strongest chassis on the grid, particularly in technical sections and high-downforce environments. The missing ingredient has often been outright power and top-speed performance compared to Mercedes and, on some occasions, Red Bull.
A successful two-stage engine upgrade program could therefore transform Ferrari’s competitiveness during the second half of the season. By combining its highly praised chassis with a more powerful and efficient power unit, the Scuderia hopes to give Lewis Hamilton and Charles Leclerc the tools needed to challenge more consistently for victories.
With the FIA’s decision on ADUO expected soon, Ferrari’s engine development roadmap may become one of the most closely watched stories in Formula 1 over the coming months.
