Formula 1 will have important changes starting from the 2026 Miami GP, and the focus now shifts to understanding the real impact of these alterations on car behavior. After criticism in the first races, the FIA adjusted key points of the regulations to improve performance, safety, and the dynamics of disputes.

The changes mainly affect energy management, which had been the target of complaints for limiting driver performance. With the new parameters, the idea is to allow more aggressive driving and reduce situations considered artificial in the sessions.
In qualifying, the main change is the reduction of the energy recharge limit per lap, which dropped from 8MJ to 7MJ. With less energy available to recover, drivers should rely less on economy strategies and will be able to explore more of the car’s performance throughout the lap.
Another important point is the increase in super clipping power, which went from 250kW to 350kW. This reduces the need to lift off the throttle to recharge the battery, favoring more consistent laps closer to the limit. The FIA also expanded the number of stages with alternative energy limits, allowing greater adaptation to the profile of each circuit.
In races, the goal is to reduce abrupt speed differences between cars. The use of boost will now have a limit of +150kW, which should prevent dangerous approaches caused by power differences at certain moments.
MGU-K control has also been adjusted. While the maximum power of 350kW will be maintained in acceleration zones, in other parts of the track the limit will be reduced to 250kW. This should make power delivery more predictable throughout the lap.

Starts are also being evaluated, with the introduction of a system that identifies acceleration below expectations after clutch release. In these cases, the car automatically activates the MGU-K to ensure a more consistent start, in addition to alerting other drivers with light signals.
Another correction involves the energy system before the start, with the counter being reset at the beginning of the formation lap. The measure seeks to eliminate inconsistencies that affected car behavior already in the first laps.
For races in wet conditions, the changes aim to improve control and visibility. The temperature of intermediate tires will be increased to generate more initial grip, while the use of ERS will be reduced to prevent loss of control on slippery tracks.
The rear light system has also been simplified, with clearer signals to facilitate driver readability in adverse conditions.
With this package, Formula 1 tries to correct distortions seen at the beginning of 2026 and give drivers greater prominence. The practical effect of the changes will begin to be observed already in Miami, when the category enters a new phase within the current generation of cars.
