The Formula 1 Commission convened recently, where discussions primarily centered around the forthcoming 2026 power unit regulations. This marked their second meeting of the season, and a significant concern emerged regarding energy deployment from the vehicles.
Among the issues raised was the concern about how energy deployment might be tweaked due to fears over battery depletion during races. "There are concerns that at circuits where regeneration opportunities are limited, such as Monza or Jeddah, cars could run low on battery power toward the end of long straights," said a representative familiar with the discussions.
Next season, F1 will transition to a revised 1.6-liter V6 hybrid engine, with a 50/50 power output ratio between electrical deployment and internal combustion engines, specifically set at 350kW for electrical output. However, the sudden introduction of a proposal for a switch to naturally aspirated V10 engines burning sustainable fuels stirred significant controversy.

FIA President Mohammed Ben Sulayem had proposed this dramatic shift for 2026, but during a preliminary meeting between the power unit manufacturers, FIA, and FOM ahead of the Bahrain Grand Prix, the notion was quickly dismissed. "The initial resistance to the V10 idea signals a larger conversation about what F1 vehicles will look like in the future," explained an F1 executive.
At the Geneva meeting of the F1 Commission, chair Nikolas Tombazis, along with F1 President and CEO Stefano Domenicali, introduced the idea of reducing electrical output to 200kW while implementing a 'Push-to-Pass' system that would use the full 350kW. This approach was received with skepticism from several manufacturers, including Mercedes, Honda, and Audi, who opposed the decrease in energy deployment.
"Reducing the electrical output would strip our energy recovery systems of their performance potential, which is a significant competitive edge,” highlighted a spokesperson for Mercedes.
This sentiment was echoed by other manufacturers during discussions surrounding potential changes. Following the F1 Commission meeting, momentum for the V10 proposal effectively stalled. Only Ferrari and Red Bull's RBPT showed some openness about exploring this idea further, but neither committed to pursuing it.
"We're still open to discussing minor adjustments to the engine regulations, but reducing electrical output isn’t a minor tweak; it fundamentally changes the nature of our current strategy," a representative for Honda stated. Despite there being room to discuss soft refinements to the regulations, the overall consensus was that such a move raised critical fundamental issues.
As the Commission continues its work, topics such as energy deployment tactics and how to address the financial challenges faced by power unit manufacturers struggling with competitiveness or reliability issues will be reviewed by the Power Unit Advisory Committee.
Alongside these discussions, improvements to the current 2025 Sporting Regulations have also been green-lit. These updates will soon go before the World Motor Sport Council for approval, and they include changes like enforcing a mandatory two-stop strategy during the Monaco Grand Prix, updating parc fermé rules in relation to the new Heat Hazard regulations, and establishing measures to cope with freight delays during international races.
The future of F1's power unit regulations hangs in the balance as these discussions unfold, with manufacturers keen to protect competitive advantages while looking toward sustainable innovations. The decisions made in the upcoming months could set the tone for the sport’s technological trajectory in the years to come.
