Formula 1’s decision to overhaul its 2027 power unit regulations has been praised by FIA president Mohammed Ben Sulayem, who has highlighted the collaborative effort behind the agreement.
After weeks of discussions involving the FIA, Formula 1, and power unit manufacturers, an agreement has been reached on revisions to the sport’s upcoming engine regulations, paving the way for changes that are expected to improve racing while preserving the championship’s long-term ambitions.
The revised plans will alter the balance between internal combustion engine power and electrical energy from 2027 onwards, addressing concerns that had emerged over the original concept.
For Ben Sulayem, the breakthrough represents far more than a technical adjustment. It is evidence that Formula 1’s stakeholders can unite behind a common goal when the future of the sport is at stake.
“Formula 1 has always evolved to meet new challenges and seize new opportunities," he said.
A new direction for the next generation of F1 engines
The sport’s forthcoming power units had been designed around an equal 50:50 split between combustion-engine output and electrical power.
While ambitious from a technological standpoint, the concept attracted criticism as simulations and testing highlighted concerns over performance once battery energy was depleted.
Several drivers voiced frustrations that cars could become significantly less competitive during certain phases of a lap, prompting further evaluation of the regulations before their introduction.
The result is a revised roadmap.
From 2027, Formula 1 will move to a 58:42 balance between combustion-engine and battery power before progressing to a 60:40 split in 2028. To support the transition, fuel flow to the internal combustion engine will also be increased over the two-year period.
The proposals are scheduled to be formally presented to the FIA World Motor Sport Council later this month, with approval widely anticipated.

"These proposed changes reflect the collaborative work taking place across the sport to ensure the regulations continue to support exciting racing, technological innovation and long-term sustainability, he added.
"The FIA has a responsibility to protect the future of the Championship, and these refinements are part of that commitment."
Collaboration drives progress
Rather than becoming a source of division, the debate over the future engine formula evolved into a collective effort to strengthen the championship.
Teams, manufacturers, Formula 1 executives and FIA officials spent weeks assessing possible solutions, eventually arriving at a compromise that sought to balance performance, sustainability and entertainment.
The process left Ben Sulayem encouraged by the spirit of cooperation shown across the paddock.
"It is through working together that we will shape the future of our sport and deliver for fans across the world, and I would like to thank the FIA staff, the teams, Formula One Group, and the power unit manufacturers for this constructive approach."
As Formula 1 prepares for a new era of engine technology, the message from the FIA president is clear: innovation remains at the heart of the championship, but progress is achieved fastest when the entire sport moves forward together.
