FIA preparing major Formula 1 power unit changes for 2027
The FIA is continuing to reshape the future of Formula 1 by defining the expected regulations for both the 2026 and 2027 seasons. From promoting the safety package tested during the Miami Grand Prix to introducing a significant power unit revolution involving the transfer of 50 kW toward the internal combustion engine — alongside an equivalent reduction in recoverable electric energy — several major changes have now been approved in principle.
FIA summit focuses on Miami lessons and Formula 1 safety
The evolution of Formula 1 shows no sign of slowing down. During an extremely important virtual summit convened directly by the FIA, the highest levels of the sport outlined the strict guidelines that will shape the coming seasons.
All institutional stakeholders attended the meeting, including team principals, Formula One Management delegates and key representatives from the power unit manufacturers.
Throughout the session, participants examined a dense package of proposals designed to modify both the hardware architecture of the 2027 regulations and certain aspects of the 2026 rules as well. The discussions ultimately led to a broad principle agreement that could become a major turning point for the entire championship.
The meeting opened with an extensive review of the recent modifications introduced during the Miami Grand Prix weekend.
After already changing the Formula 1 parameters linked to the ADUO concession system, the FIA also focused on long-term regulatory considerations. The overall conclusion emerging after the implementation of the Miami updates — specifically designed to raise safety standards and reduce the excessive exploitation of technical resources — was widely positive.
According to all parties involved, those interventions helped improve competitiveness while representing a clear step in the right direction for the future of Formula 1.
Further Formula 1 changes already under evaluation for Canada
Following extensive analysis, the FIA formally confirmed that no significant problems or major safety concerns were detected during the Miami Grand Prix weekend.
However, the evaluation process surrounding the new package remains ongoing as the governing body continues studying its future implementation for upcoming events.
The FIA agenda already includes further revisions aimed at constantly improving safety during the delicate starting phases of races, as well as additional measures designed to better protect drivers in wet-track conditions. These directives will be communicated to teams once finalized. In the short term, ahead of the upcoming Canadian Grand Prix, important improvements to visual signaling systems are also being rigorously evaluated.
Formula 1 2027 power units set for major rebalance
Moving to the examination of longer-term measures, a strong agreement reportedly emerged between all involved parties. There is now unanimous commitment toward introducing structural modifications capable of further improving both sporting fairness and safety standards across Formula 1.
The FIA’s objective is to make the regulations more intuitive both for drivers and for the operational dynamics of teams, always acting in the best interests of the sport.
The central element of this revolution — whose essential measures have already been approved in principle for the 2027 season — directly targets the architecture of the power units themselves.
In order to rebalance the relative importance of the propulsion systems, the FIA plans to introduce a nominal increase of approximately 50 kW in power generated by the internal combustion engine. This increase would be achieved through a proportional rise in fuel flow.
At the same time, however, a natural counterbalance has also been approved. The FIA has agreed to reduce the deployment power of the energy recovery system (ERS) by approximately 50 kW. In practical terms, Formula 1 would therefore shift part of the current hybrid emphasis back toward the traditional combustion engine. Despite this broad agreement, all parties also acknowledged that further detailed discussions between technical groups, teams and manufacturers will still be necessary before the final package can officially be defined.
All of this unfolds while discussions about a potential future return of V8 engines continue gaining momentum behind the scenes.
Formula 1 continuing discussions before final approval
These proposals represent the result of countless consultations carried out over recent weeks between the FIA and all major stakeholders involved in Formula 1, including valuable contributions from the drivers themselves.
The next institutional step will involve formally presenting the finalized regulatory changes for electronic approval by the World Motor Sport Council. This process will take place only after the power unit manufacturers have fully expressed their positions regarding the proposed package. The 2026 Formula 1 regulations were originally developed through close collaboration between the FIA, Formula One Management, teams and manufacturers. According to those involved, the latest discussions have maintained that same spirit of cooperation.
The immediate objective remains clear: while waiting for the deeper 2027 revolution, Formula 1 is already trying to make the 2026 regulatory framework more efficient, balanced and sustainable for the future of the sport.
