Jun.28 (GMM) The FIA has published the full technical regulations for Formula 1’s 2027 season, confirming sweeping changes aimed at improving the controversial new hybrid era.
After months of debate, the World Motor Sport Council formally approved the rules last week before the FIA released the complete 278-page regulations.
According to Auto Motor und Sport, the biggest changes further boost both the combustion engine and hybrid system after widespread criticism of the 2026 regulations.
Maximum fuel energy flow, maximum ERs output and useable battery energy per lap are all rising, while new speed-dependent power deployment and overtaking modes are also introduced.
The FIA has also simplified underfloor aerodynamics, revised flexibility tests, increased the minimum driver weight including ballast to 82 kilograms and streamlined several safety requirements.
The latest changes come after the FIA and Formula 1 already agreed to rebalance the engine regulations for 2027 and 2028 following extensive discussions with teams and drivers.
Austrian GP pole sitter George Russell believes the adjustments already made during the season have improved the current cars.
“I think the evolution with the regulation change from Japan onwards has been very good,” he said. “The cars do feel much nicer to drive.”
However, Russell said one major complaint remains.
“I think the one issue that all of the drivers are complaining about are the tyre pressures. But from what we hear and understand, Pirelli are trying to make improvements there.
“For all of us, it’s like you have big balloons you’re driving on. If they could make that step, I think it would be much better for the drivers, much better for racing, less overheating.
“We could fight even closer. I think that would be the next big step.”
Ferrari’s Charles Leclerc agreed the situation has improved, but said drivers are still forced to think too much about energy management.
“If you ask me what do I prefer between this year’s cars or last year’s cars, I think last year’s cars were… we could still push those cars to the absolute limits on some tracks.
“It’s true what George says, that it’s getting better. But still, you’ve got this energy management in mind on a track like this, for example.
“It was less the case in Barcelona or in Monaco, but there are still those tracks where you’ve got to keep that in mind, and that is a little bit less pleasure inside the car.
“But it’s like this for now. I’m sure things will improve.”
