Formula 1 is set to undergo a major transformation from 2026, but there are still gaps in the new regulations and aspects that need to be ironed out. That is why F1 has made a last-minute change that affects the much-feared power unit. This change affects all teams and has a particular impact on Aston Martin and Honda, who are now looking for ways to adapt to a new context that is emerging as they go along and which could disrupt many of the plans they already have in place.
With the elimination of the MGU-H and the increased importance of the electrical system in powering the cars, the FIA has decided to modify certain parts of the regulations so that the cars do not depend too much on conservative driving strategies, especially during qualifying.
Aston Martin and Honda
The new regulations for next season were intended to give more prominence to electrification, with a 50% – 50% split between internal combustion engines and electric systems. Once the teams had carried out some simulations with the new prototypes, they discovered that there was a major problem, namely the lack of efficient energy recovery on some circuits. This poses a problem for the MGU-H.
The FIA has therefore introduced a key change, limiting the energy that can be recovered during qualifying to just 5 MJ per lap on tracks where this is required, compared to the 8.5 MJ initially planned. This measure aims to prevent drivers from adopting unnatural driving styles, such as lifting off the throttle early or braking strategically, as they believe this jeopardizes the spectacle and safety.
For Aston Martin and Honda, these changes represent a significant technical challenge. The Japanese manufacturer has been working on its new power unit for many months in accordance with the original parameters set by the regulations, and an adjustment of this kind could force them to change their roadmap in terms of power delivery and energy recovery.
Aston Martin’s energy management
Another important aspect has been the limitation of electric power. As speeds increase, this limitation will be gradually reduced to 345 km/h, at which point it will disappear, except when overtaking (replacing the current DRS), when there will be no limitation (355 km/h).
These restrictions will have a major impact on how drivers manage their energy per lap. Mercedes driver Antonelli said: “On circuits like Monza, you could end up relying solely on the combustion engine.” In the case of Aston Martin, they will have to optimize not only the performance of the car, but also the energy efficiency of the hybrid system.
In addition, the FIA is expected to complement these measures with new developments in aerodynamics to reduce drag on straights, which will also have a direct impact on energy management.
Key to 2026
With these latest changes, the FIA seeks to safeguard the competitiveness of F1 without sacrificing the spectacle.
The technical revolution of 2026 continues to advance, but with adjustments that highlight the difficult task of balancing sustainability, performance, and entertainment.
The 2026 season will be a new beginning for all teams and will mean a change to which they will have to adapt quickly. It is clear that next year’s F1 will demand a more comprehensive approach than ever before, where every detail can make a difference.
