The introduction of the 2026 Formula 1® power unit regulations has sparked considerable discussion within the paddock and among fans. Central to the debate is the increased emphasis on electric power in the new power units, which has drawn criticism from some drivers and observers. The FIA has now provided insight into why it was unable to intervene earlier to amend these controversial rules.
Nikolas Tombazis, the FIA’s single-seater director, explained that governance agreements signed before the 2026 season between the FIA, power unit manufacturers, and Formula One Management (FOM) restricted the FIA’s ability to make unilateral changes to the regulations. These agreements required a supermajority approval from manufacturers to alter the rules, limiting the FIA’s flexibility despite early awareness of potential issues. The agreements also aimed to maintain financial and operational fairness, particularly for new manufacturers such as Audi.
This governance framework meant that although driver feedback—including outspoken criticism from Max Verstappen and Oscar Piastri—highlighted concerns about the heavy electric power split and software complexity, the FIA was constrained from making significant adjustments before the season began. Verstappen notably described the new power units as "Formula E on steroids," while Piastri pointed to the unpredictability of the power unit software. Tombazis acknowledged these criticisms as expected and part of the natural process of introducing new technical regulations.
Despite these challenges, Tombazis noted that the first half of the 2026 season has delivered competitive racing, even though Mercedes has maintained a clear advantage. The shift in the automotive industry towards electrification has influenced the design of the power units, complicating efforts to balance combustion and electric power outputs effectively. The FIA regrets not being able to introduce planned adjustments for 2027 and 2028 sooner, which aim to move the power split closer to a 60-40 ratio between combustion and electric components.
The governance agreements were designed to protect the interests of all manufacturers, ensuring a level playing field and encouraging new entrants like Audi to join the championship. This approach, while limiting rapid regulatory changes, reflects the complexity of managing technical innovation alongside commercial and competitive fairness in Formula 1®.
Looking ahead, the FIA plans to implement the scheduled changes for 2027 and 2028, addressing some of the concerns raised during the current season. Meanwhile, the ongoing season continues to test the new power unit formula under real race conditions, providing valuable data and experience for all stakeholders involved.
Overall, the FIA’s explanation highlights the balance between regulatory stability and responsiveness in Formula 1®, especially when introducing significant technical changes. The constraints imposed by governance agreements have shaped the pace and scope of adjustments to the 2026 power unit regulations, reflecting the broader challenges of evolving the sport’s technology within a complex stakeholder environment.
