The FIA has confirmed a change to the F1 regulations from the 2027 season following complaints from several drivers during the opening rounds of the current campaign.
Many drivers have taken issue with the new power units and the influence of the battery, feeling that extracting performance relies more on who has more energy, rather than the drivers being able to exploit their talents.
The FIA has communicated that the proposed changes aim to “make qualifying more flat-out while not impacting the positive and exciting racing generated by the new regulations.”
From 2027, the FIA has confirmed it will adjust the regulations, which will see the power split skewed in favour of the combustion engine.
This element will see its power output increase to 420kW, with a fuel flow increase of five per cent.
The battery will decrease to 300kW, however, the drivers will have more harvesting power available with an increase to 350kW.
There will then be a further swing for the 2028 season, with the engine power raised again to 450kW and the fuel flow increased by 13 per cent.
The electrical element will retain a 300kW output while the harvesting power will also increase to 400kW.
Now, the proposed changes will be submitted to the World Motor Sport Council for formal approval on June 23.
