What's happened
The FIA has announced staged changes to the engine-electrical power split for 2027 and 2028 to address driver frustration with energy management. The transition will begin at 58-42 in 2027 with a 5% fuel-flow rise, moving to 60-40 in 2028 alongside a larger power output from ICE. The adjustments aim to increase on-track outright pace without major hardware overhauls, while discussions continue with teams and manufacturers.
What's behind the headline?
Critical perspective
- This shift signals a strategic move to enhance outright speed while preserving racing dynamics. The incremental approach reduces the risk of costly, rapid changes to power units.
- The timeline keeps manufacturers like Audi and Ferrari engaged in the decision, balancing performance gains with cost and feasibility.
- The change could reshape team strategies over the coming seasons, with more engine power available for overtakes and potentially different energy-management tactics on track.
- Forecast: if approved, teams will adapt software and fueling strategies; hardware remains largely unchanged for 2027, with more substantial gains in 2028.
How we got here
Changes to F1 power unit rules have been debated for months, with drivers like Max Verstappen pushing for more aggressive shifts. The 2026 cars ran with a roughly 53-47 split, favoring the engine, and the current plan broadens the use of ICE power while gradually easing in more fuel flow. Formal approval is expected before the end of June.
Our analysis
The Guardian notes a staged 2027 start at 58-42 with a 5% fuel-flow increase, rising to 60-40 in 2028 and up to 13% fuel flow. AP News confirms the same 2027/2028 power split and emphasizes a move toward more engine power and less reliance on battery energy. Both publications highlight pressure from teams and manufacturers to avoid costly hardware changes while improving racing quality.
