The FIA World Motor Sport Council has officially approved rule changes to the 2027 Formula 1 power unit regulations, moving towards a greater reliance on internal combustion engines. The decision, ratified during the WMSC's mid-2026 meeting at the FIA Conference in Macau, will see a 58-42 split between internal combustion and electrical power in 2027, followed by a 60-40 split in 2028. These changes directly address concerns raised by drivers, particularly Max Verstappen, who had threatened to leave the sport over the original 2026 rules.
Verstappen's Frustration with 2026 Rules
Verstappen had publicly stated in March 2026 that he was considering walking away from F1 at the end of the season due to frustrations with the new power unit regulations. The original 2026 rules mandated a rough 50-50 split between internal combustion and electrical power, forcing drivers to adopt unnatural driving styles to optimise lap times by conserving battery energy and regenerating power throughout a lap. The Dutch driver's discontent highlighted a broader issue within the paddock, as teams and drivers struggled to adapt to the all-new engines powered by fully sustainable fuels introduced at the start of the 2026 season.
Negotiations and Agreement
Following Verstappen's comments and widespread criticism from other drivers, talks were initiated between all parties across F1. It was quickly agreed that a move towards a 60-40 split in favour of internal combustion would reduce the need for excessive energy management, making the cars more natural to drive. The WMSC's ratification of these changes now formally incorporates them into the FIA Technical Regulations from 2027 onwards. The shift is designed to balance performance, sustainability, and driver satisfaction without compromising the championship's commitment to sustainable fuels.
FIA President's Statement
FIA President Mohammed Ben Sulayem commented on the decision: "The FIA continues to oversee the evolution of the 2026 regulations and work closely with all key stakeholders across the motorsport community. As with every major regulatory change, the process does not end when the cars first take to the track. Continuous dialogue and collaboration are essential to ensuring that the regulations meet the needs of the sport, its drivers, and its fans." He added: "Together we are exploring the future direction of the championship and considering how the sport can balance innovation, sustainability, performance and fan appeal in the years ahead. The discussions around future power unit concepts, including V8 engines powered by sustainable fuels, demonstrate the willingness of all parties to engage in shaping the next chapter of the sport."
Impact on the Championship
The rule changes are expected to have a significant impact on team strategies and car design from 2027. By increasing the internal combustion engine's share of power, teams may focus more on improving ICE efficiency while reducing the complexity and weight of hybrid systems. For drivers, the change promises a more intuitive driving experience, potentially leading to closer racing and more overtaking opportunities. The move also aligns with F1's broader goal of maintaining its position as a pinnacle of motorsport technology while ensuring the sport remains exciting for fans.
