FIA approves power split crucial to Max Verstappen's F1 future

The FIA has ratified proposed changes to Formula 1 power units, moving away from the 50/50 power split that has frustrated drivers, most notably Max Verstappen. 

Ahead of May's Miami Grand Prix, proposals were discussed in a meeting between the FIA, F1, teams and power unit supplier, which would see the 50/50 power split between the internal combustion engine [ICE] and the electrical element dropped. 

While changes enacted for that round were widely welcomed, Verstappen described the action as just a "tickle", with large alterations needed. His continued threats to quit should the changes not be implemented were described as "real" by former Red Bull chief Richard Hopkins.

The approved proposals will see a steady increase in focus on the ICE across the coming seasons, with a 60/40 split being reached by 2028.

This will involve a 450kW output from the ICE - an increase of 50kW from the current power units - and a drop to 300kW maximum power from the MGU-K. However, overtake mode will remain at 350kW, and the maximum harvesting power will increase from 350kW to 400kW.

To gain the extra power from the ICE, the fuel flow rate will be increased by 5% in 2027, and 13% in 2028. This change previously caused concern, with suggestions that races could be shortened as a result. This is in part due to the cost cap implications of creating cars to all-new regulations this term, with some teams having hoped to carry their chassis into 2027 to balance the books. In this instance, simply fitting a larger fuel tank would not be an option.

The gradual switch to the eventual 60/40 split is likely a reaction to this, after there had been suggestions of shortening grand prix distances to negate the fuel difference. 

“The first half of 2026 has been characterised by progress," said FIA President Mohammed Ben Sulayem. 

"We have witnessed new race winners and emerging talent across our championships and celebrated iconic events including the Monaco Grand Prix and the 24 Hours of Le Mans, showcasing the very best of our sport to millions of fans globally. We continue to deliver on our commitment to create motorsport that is safe, exciting, sustainable and accessible. 

"These achievements are only possible because of the efforts of this World Motor Sport Council, our Members, and our entire FIA community.”
