Formula 1 is about to enter a brand-new technological era and, as often happens when a major paradigm shift takes place, innovation is moving faster than certainty. Just over a month before the debut of the 2026 power units, a very specific concern is spreading among engineers up and down the pit lane: the possible return of clipping, a phenomenon capable of turning a straight into a real nightmare. However, according to several reports, some manufacturers may already have found a way to neutralise it.
The clipping issue: the biggest risk of the post-MGU-H era
The removal of the MGU-H, considered too expensive and overly complex, has forced Formula 1 to completely rethink the hybrid architecture of its power units. The new balance will be built almost entirely around the MGU-K, whose output will be tripled to reach 350 kW. It is a huge leap forward in electrical power, but one that inevitably comes with significant consequences.
Without the continuous energy recovery previously guaranteed by the MGU-H, there is a concrete risk that the battery may not be able to sustain maximum deployment for an entire lap. This scenario becomes even more critical on full-throttle circuits such as Monza, where long straights place extreme demands on the hybrid system.
The result could be the dreaded clipping effect: a sudden and noticeable loss of power on the straights, leading to a drop in top speed. Beyond the performance implications, clipping could also raise safety concerns, especially when two cars are running in close proximity and one unexpectedly slows down while in another car’s slipstream.
The solution: turning the V6 into an intelligent generator
According to information reported by Motorsport.it, Mercedes, Red Bull Powertrains and Audi are believed to have identified an innovative strategy to work around this potential problem. The concept is based on highly advanced engine mappings designed to convert part of the fuel’s energy directly into electrical energy.
In practical terms, during cornering phases or sections of the track driven at partial throttle, a portion of the V6 internal combustion engine’s power would be diverted to the MGU-K in order to recharge the battery. It is a carefully calculated compromise: a small sacrifice in thermal power during less critical moments of the lap, in exchange for a more stable and reliable electrical reserve over the full distance.
The benefits of such an approach would be twofold. On the one hand, it could help reduce turbo lag, improving drivability and throttle response. On the other, it would significantly lower the risk of clipping, ensuring more consistent speed along the straights and a more predictable power delivery profile.
If this solution proves to be genuinely effective in real-world conditions, the 2026 Formula 1 season could open the door to two opposing philosophies. Some teams may choose to run with more fuel on board to support aggressive battery recharging strategies, while others could opt for a lighter and more aggressive approach, accepting a higher level of risk. One thing is certain: the next great battle in Formula 1 will not be fought solely on the track, but also deep within software algorithms and energy management choices that will define the future of the sport’s new hybrid era.
