      Yesterday, the FIA introduced a series of adjustments to the somewhat contentious 2026 Formula 1 regulations. As is typical in F1, some teams supported these changes while others opposed them. Some voices were more vocal than others regarding the necessity of alterations, yet the regulations have been modified regardless.

      The information and details provided by the FIA can be somewhat challenging to interpret, especially for those unfamiliar with the legal jargon. While the changes are not extensive and primarily focus on the use of electric energy, several aspects could be explained in simpler terms.

      Here’s what you need to know about the updated regulations that will take effect at the 2026 Miami Grand Prix.

      Energy Management

      "Super clipping" has become a key term in discussions today. This concept can be understood as utilizing combustion power to produce electric power, similar to EV chargers powered by gasoline generators. In this instance, however, those generators will be towed behind an F1 car at all times.

      Starting next week, the management of battery energy will change during laps when harvesting or deploying energy. Specifically, the energy recovery during super clipping will increase from 250 kilowatts to a maximum of 350 kilowatts. In essence, this means that performance will not be as heavily penalized when a car is at its maximum speed at the end of a straight. Drivers will now be able to store more energy in their batteries while fully accelerating compared to before. This adjustment offers both performance and safety enhancements, which will be further explained later.

      Top speed will still be influenced as it was prior to the updates, so the challenges associated with super clipping will not be completely resolved. Depending on the circuit layout, a vehicle might run out of power before reaching the end of a straight (consider long straights like those in Baku or Mexico City). However, drivers will now be able to recover more energy at a lower cost, in a manner, allowing them to drive harder and faster, particularly during qualifying.

      Several adjustments regarding qualifying and starting procedures were also unanimously agreed upon by all teams. Notably, the energy harvesting limit will be decreased from eight megajoules to seven starting in Miami. This shift aims to decrease reliance on electric power and increase the use of the combustion engine throughout a lap, leading to less coasting and super clipping, while also resulting in slower speeds due to diminished battery power. Although this is likely to result in longer lap times than before, it will require drivers to push their cars to their limits without assistance, potentially making the qualifying sessions more thrilling. It seems that slower is now preferred?

      Safety

      Overall, the FIA aimed to enhance situations involving speed discrepancies and lift-and-coast techniques. Reducing the harvesting limit during qualifying will minimize the time a vehicle spends super clipping in a lap, expecting it to be cut down to just 2 to 4 seconds. Furthermore, the harvesting limit can be further reduced for several tracks on the calendar, depending on their configurations.

      This approach was tested in Japan and appears to have provided satisfactory results warranting its standardization, though, as mentioned earlier, adjustments may continue throughout the season.

      In terms of safety, MGU-K deployment remains at 350 kilowatts in “key acceleration zones,” but will drop to 250 kilowatts in other sections of the track. This should mitigate the risks associated with speed differentials, which could result in incidents like the crash involving Oliver Bearman and Franco Colapinto at Suzuka—although I think this issue is not solely responsible for that accident.

      The FIA will also modify deployment rules. MGU-K deployment will stay at 350 kilowatts in key acceleration zones but will be restricted to 250 kilowatts in other parts of the track. Additionally, the maximum power available through boost mode during races is now capped at +150 kW.

      In wet conditions, this latest set of adjustments will also raise tire blanket temperatures specifically for Intermediate tires, allowing drivers to achieve better grip right after leaving the pit lane. Similarly, energy deployment will be limited during wet races, and warning light sequences will be activated.

      A new "low power start detection" system will be trialed in Miami, which will essentially initiate automatic MGU-K deployment to assist a car’s start if the driver struggles with it. This measure aims to lower the chances of getting rear-ended by another car accelerating at full speed.

      Conclusion

      Despite Toto Wolff’s concerns that the FIA is employing a "bat" rather than a "scalpel" to address the 2026 regulations, these appear to be minor modifications with the
