A series of targeted updates to the 2026 Formula 1 regulations have been confirmed following recent discussions between the FIA, Formula 1, teams and power unit manufacturers – with changes set to roll out from the Miami Grand Prix.
The refinements come after analysis of the opening races in Australia, China and Japan, alongside feedback from drivers and technical teams, with a focus on improving performance, safety and overall racing quality.
As outlined by the FIA, the agreed updates fall across four key areas:
Qualifying – promoting performance
Adjustments to energy management parameters, including a reduction in maximum permitted recharge from 8MJ to 7MJ, aimed at reducing excessive harvesting and encouraging more consistent flat-out driving. This change targets a maximum superclip duration reduced to approximately two to four seconds per lap.
Peak superclip power increased to 350 kW, previously being 250 kW, further reducing the time spent recharging, and reducing driver workload on energy management. This will also be applied in race conditions.
The number of events where alternative lower energy limits may apply has been increased from eight to 12 races, allowing greater adaptation to circuit characteristics.
Race – improved safety and consistency of performance
The maximum power available through the Boost in race conditions is now capped at +150 kW (or the car’s current power level at activation if higher) limiting sudden performance differentials.
MGU-K deployment is maintained at 350 kW in key acceleration zones (from corner exit to braking point, including overtaking zones) but will be limited to 250 kW in other parts of the lap.
These measures are designed to reduce excessive closing speeds while maintaining overtaking opportunities and overall performance characteristics.

Race starts – enhanced safety mechanisms
A new ‘low power start detection’ system has been developed, capable of identifying cars with abnormally low acceleration shortly after clutch release.
In such cases, an automatic MGU-K deployment will be triggered to ensure a minimum level of acceleration and mitigate start-related risks without introducing any sporting advantage.
An associated visual warning system is being introduced, activating flashing lights (rear and lateral) on affected cars to alert following drivers.
A reset of the energy counter at the start of the formation lap has also been implemented to correct a previously identified system inconsistency.
Wet conditions – improving safety and visibility
Tyre blanket temperatures for intermediate tyres have been increased following driver feedback in order to improve initial grip and tyre performance in wet conditions.
Maximum ERS deployment will be reduced, limiting torque and improving car control in low-grip conditions.
The rear light systems have been simplified, with clearer and more consistent visual cues to improve visibility and reaction time for following drivers in poor conditions.
These final proposals will now be put before an FIA World Motor Sport Council e-vote before their planned implementation.
Writing on X after the updates were agreed, Team Principal James Vowles shared: “These are sensible changes and the teams, FIA and Formula 1 have done good work over the past few weeks to agree them.
“F1 has seen some great racing so far this year but it is right that we always look at ways to keep improving. We look forward to seeing them in action from Miami onwards.”
