Ferrari faces mounting pressure over ADUO approval amid SF-26 EVO engine deficit. Ferrari faces defining moment with ADUO ruling .

Ferrari’s 2026 Formula 1 campaign is entering a delicate phase, with growing concerns inside Maranello regarding the approval of the much-discussed ADUO engine adjustment. What initially appeared to be a technical necessity is now evolving into a broader political battle, one that could significantly influence Ferrari’s competitiveness against its main rivals.

The Miami Grand Prix weekend delivered a clear and concerning verdict for the Scuderia. On a circuit defined by long straights and high-speed sections, the Ferrari SF-26 EVO struggled to match the performance of its direct competitors, despite introducing the updated rear wing package often referred to internally as the “Macarena” specification. While the aerodynamic tweak aimed to reduce drag and improve top speed, the gains were not sufficient to offset the power unit disadvantage.

Data from the Florida round confirmed that both Mercedes and McLaren held a decisive advantage in straight-line speed. The Mercedes-powered cars, in particular, demonstrated superior acceleration and top-end performance, consistently pulling away from Ferrari on the straights. This gap exposed a fundamental limitation in the current Ferrari package, one that cannot be resolved through aerodynamic adjustments alone.

Both Lewis Hamilton and Charles Leclerc acknowledged the issue over the Miami weekend, indicating that the deficit on the straights remains too significant to ignore. Internally, Ferrari has recognized that only the introduction of the ADUO mechanism could help bridge this gap and restore a more balanced level of performance relative to its rivals. The expectation within the paddock is that a final decision could come after the Canadian Grand Prix, a circuit that will once again emphasize engine efficiency and top speed.

However, Montreal is also shaping up to be another challenging venue for Ferrari. The Circuit Gilles Villeneuve, with its long straights and heavy braking zones, tends to reward power unit performance, further amplifying the Scuderia’s current weaknesses. As a result, the pressure on Ferrari to secure ADUO approval is intensifying with each passing race weekend.

Rising concerns over FIA decision and political implications

The FIA, through its Single-Seater Director Nikolas Tombazis, has indicated that the Canadian Grand Prix will serve as a critical reference point for evaluating the current balance of power units across the grid. This benchmark could play a decisive role in determining whether Ferrari is granted the requested 4% ADUO adjustment.

Despite internal data suggesting that Ferrari has a legitimate case, there is increasing uncertainty within the team regarding the final outcome. Reports from the Italian media indicate that apprehension is growing in Maranello, with doubts emerging about whether the FIA will ultimately approve the measure. This cautious outlook reflects a broader awareness of the political dynamics at play within Formula 1’s regulatory environment.

Team principal Frédéric Vasseur has adopted a measured and restrained tone when addressing the situation publicly. Rather than making definitive statements, he has preferred to wait for official confirmation, a stance that suggests he may already be aware of complexities behind the scenes. His approach indicates that Ferrari is navigating not only a technical challenge but also a sensitive political negotiation.

Adding to the uncertainty is the potential regulatory intervention concerning the FTM system, specifically the flap positioned behind the exhaust. Ferrari introduced an updated version of this component in Miami, aiming to optimize airflow and extract additional performance. However, discussions within the FIA about a possible ban on such solutions could undermine Ferrari’s recent development efforts.

If enforced, this restriction would represent a significant setback for the Scuderia, not only from a technical standpoint but also in terms of political influence. It would effectively negate one of the Maranello team’s recent innovations while reinforcing the perception that competing interests are regaining strength within the sport’s decision-making processes.

In this context, Ferrari’s situation extends beyond pure performance metrics. The outcome of the ADUO discussion, combined with the potential FTM ban, could shape the competitive landscape of the 2026 Formula 1 season. For Lewis Hamilton and Charles Leclerc, the coming races will be crucial—not only in terms of results on track, but also in determining whether Ferrari can successfully defend its position within the complex political framework of Formula 1.

Ferrari is therefore facing a dual challenge: closing the technical gap to its rivals while simultaneously navigating the intricate regulatory environment that defines modern Formula 1. The next decisions taken by the FIA could prove pivotal, potentially influencing the trajectory of the Scuderia’s season and its ability to fight at the front of the grid.
