F1 Approves Engine Rule Changes for 2027 After Driver Criticism of Hybrid Power Units

Posted : 09 May 2026

Formula 1 stakeholders have reached an agreement to revise engine regulations for the 2027 season following widespread criticism of the current hybrid power unit regulations introduced this year.

Drivers have expressed concerns that the near equal split between internal combustion and electrical power has made qualifying less natural and overly dependent on energy management strategies. Many have argued that the current system reduces the ability to push consistently at full speed.

Under the proposed changes, the proportion of power generated by the internal combustion engine will be increased by 50kW (67bhp), while electrical power output will be reduced by the same amount. The aim is to allow drivers to operate more traditionally during qualifying laps.

The adjustment is also expected to reduce the need for complex energy harvesting techniques, which currently require drivers to recover energy under full throttle. This often leads to noticeable drops in speed before corners and through high-speed sections.

Officials believe the revised balance will significantly reduce these effects, although some circuits with limited energy recovery demand may still require strategic management.

The agreement was reached unanimously during a meeting involving Formula 1 management, team representatives, and the FIA. However, the final technical details will still be refined through further discussions with teams and engine manufacturers.

Additional proposals are also being explored to further simplify energy recovery systems or reduce their influence on race performance. These discussions are part of a broader effort to improve racing quality while managing costs and technical complexity.

Some teams have raised concerns about cost implications, particularly regarding chassis continuity and potential modifications such as fuel tank adjustments. Despite this, insiders suggest there is strong willingness across the paddock to embrace the challenge of development.

The meeting also acknowledged feedback from drivers regarding recent operational tweaks introduced at the Miami Grand Prix, which were widely seen as an improvement but still insufficient.

Lando Norris summed up the sentiment by saying that while the changes were a step in the right direction, current regulations still penalise drivers for pushing at maximum performance, something he believes should not happen in Formula 1.
