The FIA (International Automobile Federation) and Liberty Media have intensified negotiations with engine manufacturers to finalize the Formula 1 power unit regulations for 2027. An agreement is expected to be concluded during the Spanish GP, between June 12 and 14, according to Motorsport.

The federation intends to adjust the rules and reduce the participation of electrical energy compared to the current model, which foresees a division close to 50% between electrical and combustion power. Before the Canadian GP, manufacturers seemed to agree on the need for changes, and the FIA presented a proposal that foresaw a 14% increase in fuel flow, raising the combustion engine power by 50 kW and reducing the electric system’s power by 50 kW.
According to the FIA, the new configuration, with 450 kW from the combustion engine and 300 kW from the MGU-K, would help eliminate problems such as superclipping and excessive battery management in qualifying laps.
However, Ferrari and Audi changed their position a few days later. The automakers argued that changes of this magnitude would require significant interventions in projects already under development, with impacts on costs, reliability, and internal planning.

Behind the scenes, the fear of losing the benefits guaranteed by the ADUO would have motivated the change in stance. As an alternative, a proposal gained traction that could achieve a 60% combustion power and 40% electric power ratio without requiring profound changes to the power units.
Meanwhile, the Formula 1 Commission approved a reduction in the aerodynamic load of the 2027 cars. This measure, combined with a limited 5% increase in fuel flow, could reduce the phenomenon of lift and coast and favor energy recovery.
