The FIA, team principals, and engine manufacturers’ CEOs have agreed on a series of Formula 1 regulation changes that will take effect starting with the Miami Grand Prix, scheduled from May 1st to 3rd. These modifications aim to address criticisms from drivers following the initial three races, which featured a new 50/50 energy split between internal combustion and electric power.
Some voiced concerns that the new powertrains require drivers to focus more on strategic energy management (switching between boost and overtake modes) rather than traditional driving skills, and that the sudden bursts of acceleration from electric power increase the risk of accidents. This concern was highlighted by Oliver Bearman’s accident in the final race before this brief hiatus in April.
The primary objectives of these new rules are to bolster safety, particularly through a system designed to detect cars with abnormally low acceleration, and to cap the maximum power available from boost mode during race conditions, thereby limiting sudden performance disparities.
Qualifying – Promoting Performance
Adjustments to energy management parameters include a reduction in the maximum allowed recharge from 8MJ to 7MJ. This is intended to curb excessive harvesting and encourage more consistent, flat-out driving. This change aims for a maximum superclip duration reduced to approximately two to four seconds per lap.
The maximum superclip power has been increased to 350 kW, up from 250 kW previously. This further decreases recharge time and the driver’s workload in managing energy. This measure will also be applied during race conditions.
The number of events where alternative lower energy limits can be applied has been increased from eight to twelve races, allowing for greater adaptation to different track characteristics.
Race – Improving Safety and Performance Consistency
The maximum power available from boost during race conditions is now capped at +150 kW (or the car’s current power level at activation if higher), which limits sudden performance gaps.
MGU-K deployment will remain 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. It can identify cars with abnormally low acceleration immediately after clutch release.
In such scenarios, an automatic MGU-K deployment will be triggered to ensure a minimum level of acceleration, mitigating risks associated with a slow start without introducing a sporting advantage.
An associated visual warning system is being introduced, activating flashing lights (rear and side) on affected cars to alert following drivers.
A reset of the energy counter at the beginning of the formation lap has also been implemented to correct a previously identified system inconsistency.
Wet Conditions – Improving Safety and Visibility
Intermediate tire blanket temperatures have been increased, following driver feedback, to improve initial grip and wet-weather tire performance.
Maximum ERS deployment will be reduced, which will limit torque and improve car control in low-grip conditions.
Rear light systems have been simplified, with clearer and more consistent visual signals to enhance visibility and reaction time for following drivers in poor conditions.
These are the latest changes announced by the FIA and Formula 1, which will be implemented at the Miami Grand Prix from May 1st to 3rd, pending approval by the FIA World Motor Sport Council. What are your thoughts on these changes?
