Formula One teams have agreed on a set of adjustments to the 2026 power-unit regulations, refining how energy is recovered and deployed during races.
The changes follow extended discussions involving the Fédération Internationale de l’Automobile, team principals, engine manufacturers, and the sport’s commercial stakeholders, with the focus on improving how the new rules translate on track.
The current engine format remains in place. Cars continue to run 1.6-litre V6 turbo hybrids, but with a stronger reliance on electrical power than in previous cycles.
The removal of the MGU-H has shifted more responsibility onto the MGU-K, which now handles a significantly higher share of energy recovery and deployment.
Electric output peaks at around 350 kW, bringing it closer in balance with the internal combustion engine.
There will now be monitoring of how energy is managed across a lap. One of the key updates reduces the maximum energy that can be harvested under braking from 8 megajoules to 7 megajoules per lap.
The intention is to limit excessive recovery phases that had begun to influence driving patterns, particularly the need for drivers to lift earlier into corners to recharge systems.
That change also affects how energy is released on straights. Short bursts of deployment, often referred to as clipping phases, are now more restricted, with the window reduced to a shorter duration per lap.
This should lead to a more consistent power curve, rather than sharp variations between harvesting and deployment.
From a driving perspective, the aim is obvious. Cars should spend more time at full pace instead of alternating between saving and releasing energy.
That shift is expected to make race flow more natural, with fewer disruptions to rhythm through corners and acceleration zones.
The adjustments have been broadly accepted across the grid. Manufacturers, including Ferrari, Mercedes-Benz, Honda, Audi, Ford Motor Company-aligned Red Bull Powertrains, and Renault-linked Alpine, remain committed to the current engine direction.
This is clearly not a reset, just as teams confirmed before the meeting took place. The core structure of the 2026 regulations stays intact, with these updates aimed at refining how performance is delivered within that framework.
As more data comes in from races, further adjustments remain possible, but for now, the focus is on keeping the cars closer to full pace while maintaining the balance between efficiency and competition.
