New rules ’not a failure’ as FIA confirms 2027 changes

Formula 1’s governing body has announced significant changes to the controversial new engine regulations, following months of debate about the sport’s power unit direction.

The compromise follows sustained criticism of the original framework, which many had feared placed too much emphasis on electrical power and energy management.

Under the revised rules, fuel flow will increase by 5 percent in 2027 and by 13 percent in 2028. At the same time, the balance between combustion and electrical power will shift further towards the internal combustion engine.

The already-tweaked 53-47 split will now become 58-42 in 2027 and 60-40 in 2028. The FIA said the decision came "following concerns identified in relation to energy management under the new Power Unit framework".

"These latest amendments reflect the continuation of this collaboration with all stakeholders working collectively to refine the framework and address identified operational challenges," the governing body added.

"The FIA will now expedite the formal approval process to provide all parties with early clarity and sufficient time to adapt to the revised requirements."

The move represents a significant victory for drivers and fans who argued Formula 1 needed to move away from excessive battery dependence.

It is believed the changes will require some shortened race distances because of the upgraded fuel flow.

The agreement also indicates that resistance from manufacturers including Ferrari and Audi has now been overcome.

Honda Racing Corporation president Koji Watanabe welcomed the outcome.

"We don’t consider the new regulations to have been a failure," he told Soy Motor. "Any major new challenge comes with difficulties.

"We are pleased with our willingness to make adjustments when necessary and we maintain close communication with the FIA, FOM, and all other power unit manufacturers."
