The FIA has formalized a series of changes to the Formula 1 regulations for 2026 and took another step in defining the rules that will come into effect from 2027. The decisions were approved during the World Motor Sport Council meeting held in Macau.

Among the new measures for 2026, the entity determined that the extreme heat risk declaration may be applied separately for a Sprint and for the GP, provided it is communicated at least 24 hours in advance. Additionally, in low grip conditions, wet track, or reduced visibility, the energy boost mode was reintroduced exclusively to avoid power reduction of the cars, without generating additional performance gain. In these situations, the overtaking mode will be disabled.
The World Council also approved the increase of pre-season testing for 2027, which will go from three to four days. The FIA also ratified the first edition of the 2027 technical regulations, described as a set of structural, wording, and technical updates aimed at improving clarity, consistency, and application of the rules, incorporating learnings obtained during the 2026 season.
Another important topic was the evolution of power units. The entity confirmed the changes already proposed for the power distribution between the combustion engine and the electric systems and until 2028, will adopt a ratio of 60% for the combustion engine and 40% for the battery. The approved package also includes specific adjustments in the thermal engine power, fuel energy flow, use of the energy recovery system, and greater flexibility in energy management.

Measures related to the supply of power units, management of reconnaissance laps, race distances at certain circuits, and changes to financial regulations linked to the technical and sporting packages of 2027 and 2028 were also approved.
FIA President Mohammed Ben Sulayem highlighted that work will continue after the new rules come into effect. “The FIA continues to oversee the evolution of the 2026 regulations and is working closely with all stakeholders in the motorsport community,” he said.
“Together, we are exploring the future direction of the championship and assessing how the sport can balance innovation, sustainability, performance, and fan appeal in the coming years. Discussions about future engine concepts, including V8s powered by sustainable fuels, demonstrate the willingness of all parties to help shape the next chapter of the sport,” he added.
