Pressure from drivers forces F1 to rethink its hybrid revolution
Formula 1 rarely modifies such a significant technical regulation just a year after its implementation. However, that is precisely what has happened with the new generation of power units introduced in 2026. After months of criticism from drivers, engineers, and teams, the FIA, Formula 1, and the manufacturers agreed to reduce the role of electric power and give more weight to the combustion engine starting in 2027.

Since the 2026 regulations were introduced, several drivers warned that the planned power split between combustion and electricity could alter the very essence of the sport. The most vocal critic was Max Verstappen, who back in 2023 had already cautioned that he didn't want racing to become a competition based solely on battery regeneration.
When the cars began competing under the new rules, these concerns materialized. Drivers complained that they had to constantly manage available energy, lift off the throttle at unnatural moments, and modify their driving style to optimize electric power delivery. For many, performance no longer depended solely on pushing the limits, but on managing the battery.
Verstappen was particularly harsh. He went so far as to describe the new regulations as "anti-racing," claiming the cars were "more like Formula E on steroids" and asserting they weren't fun to drive. He also criticized the complexity of the energy regulations and maintained that many fans didn't even understand what was happening on the track.
But the criticism didn't stop at isolated statements. During the first half of 2026, the Dutchman began hinting at a possibility that set off alarm bells in the paddock: retiring from Formula 1 if the category's technical direction didn't change. In several interviews, he admitted he was considering leaving the championship because he no longer enjoyed the experience of driving these cars. Later, he publicly renewed this threat if the rules planned for 2027 weren't modified.
The concern for Formula 1 was enormous. This wasn't just any driver; it was the sporting icon of the current generation and one of the category's greatest assets. The possibility of losing their most high-profile figure right at the beginning of a new technical era represented a considerable sporting and commercial risk.
The 2026 regulations were born with a clear objective: to make Formula 1 a more attractive technological platform for manufacturers, significantly increasing the importance of the hybrid component.
The result was a power unit with an approximate distribution of:
53% combustion power.
47% electric power.
This was the closest to a 50/50 split in the modern history of the category.
On paper, the proposal aligned with the FIA's sustainability strategy and helped attract new manufacturers like Audi. However, in practice, unexpected problems arose.
On circuits with long straights, drivers could run out of electric power before the end of acceleration. This led to speed differences that were difficult for spectators to understand and forced drivers to manage energy even during qualifying laps. Some drivers even warned that sudden speed variations between cars could create potentially dangerous situations.
The FIA then begun to explore solutions. After several meetings with teams, manufacturers, and drivers, a compromise was reached that maintains the hybrid philosophy of the regulations but reduces their impact on driving.
Changes for 2027 and 2028
2026: Combustion 53% / Electric 47%
2027: Combustion 58% / Electric 42%
2028: Combustion 60% / Electric 40%
Furthermore:
In 2027, the maximum power output of the internal combustion engine will increase from 400 kW to 420 kW.
In 2028, it will increase to 450 kW.
Fuel flow will increase by 5% in 2027 and by 13% in 2028.
The amount of electric power used on a regular basis will be reduced compared to the original 2026 specification.
These changes represent much more than a simple technical modification.
First, they constitute a victory for the drivers. The FIA has implicitly acknowledged that the balance had tipped too heavily towards energy management and that it was necessary to recover some of Formula 1's traditional aggression.
Second, the decision demonstrates that the category continues to consider on-track entertainment fundamental. The aim is for drivers to push harder again during qualifying and races, reducing situations where they have to slow down to conserve energy.
There is also an important political consequence. The speed with which these newly introduced regulations were modified demonstrates the weight of criticism from figures like Verstappen. For years, the Dutchman was practically the only voice publicly questioning the 2026 regulations. Three years later, many of the concerns he raised ended up becoming the basis of the reform.
Ultimately, the decision redefines the technological direction of Formula 1. The category will remain hybrid and will use sustainable fuels, but it has made it clear that it is not willing to sacrifice the quality of racing in the name of electrification. The message is clear: innovation will remain important, but the priority continues to be enabling drivers to push to the limit and ensuring that the on-track spectacle retains the essence that has defined Formula 1 for decades.
