Formula One returns from its five‑week hiatus in Miami with a revised regulatory framework, following a coordinated effort by the FIA, Formula One Management, team principals and power unit manufacturers to refine the 2026 technical and sporting rules.

The adjustments—finalised during an online meeting on 20 April—are the result of several weeks of consultation involving FIA technical staff, team engineers and extensive driver feedback, all informed by data from the opening three rounds of the season.

While the 2026 regulations were originally shaped through a long collaborative process, the early phase of the championship exposed areas where performance consistency, safety margins and operational clarity required immediate intervention. FIA Single‑Seater Director Nikolas Tombazis stressed that the governing body’s response remains rooted in the same cooperative spirit.

“These 2026 regulations, as we’ve said a few times, are one of the biggest changes we’ve had probably in the history of Formula 1,” Tombazis said.

“They were quite important to maintain the relevance, the technological developments, with the increased electrification and so on. We knew always that they presented certain challenges, and we always said we were going to review them after the first few races.”

He added that while the new era has delivered excitement, some areas required immediate refinement: “The first few races have gone quite well in many ways.

"It has been exciting with lots of close racing and overtaking, but there certainly have been areas where we needed to intervene. So the approach we took here was one of evolution and refinement, not revolution. We don’t think there was any need for revolution.”

The most significant changes concern energy management in qualifying. The FIA has reduced the maximum permitted recharge from 8 MJ to 7 MJ, aiming to shorten the extreme harvesting cycles that have defined the early races and to allow drivers to push flat‑out for longer.

Drivers had been vocal about the difficulty of delivering a clean lap under the previous parameters, and Tombazis confirmed that their concerns were central to the revisions: “The position of the drivers was quite uniform among them.

"They were all pushing for some changes in qualifying in order to enjoy the driving more, to push more, but they were also pushing for us to address certain safety concerns they had, so they were quite united, and their input in this was very important.”

Race‑related refinements include a new cap on Boost power in race trim—limited to an additional 150 kW or the car’s current power level at activation if higher—to prevent the dramatic performance swings that contributed to several near‑misses and one major accident.

The MGU‑K will continue to deploy at 350 kW in key acceleration zones, but deployment elsewhere will now be restricted to 250 kW. This dual‑level model is intended to reduce excessive closing speeds without compromising overtaking.

Tombazis acknowledged that the Bearman–Colapinto collision in Japan accelerated the need for action: “The type of problem we saw with Oliver Bearman’s accident at Suzuka should be essentially avoided starting from the next race in Miami.”

The FIA has also introduced a new “low power start detection” system to address the inconsistent torque delivery seen at several starts this season. If a car fails to accelerate normally after clutch release, the system will intervene automatically.

Tombazis explained the rollout: “On the risks at race starts, it will probably take two or three Grands Prix to implement all the changes, but we will already carry out some tests in Miami and Montreal, putting a safety net in place.”

He detailed how the system will function: “If it is detected that a car has an extremely problematic start, the electrical system will activate and take control, ensuring that the car moves off safely to avoid risks for the drivers behind.”

Following strong driver feedback, tyre blanket temperatures for intermediates have been increased to improve initial grip. Maximum ERS deployment in wet conditions will be reduced to limit torque spikes, and rear light systems have been simplified to improve visibility in heavy spray.

Tombazis emphasised that the regulatory process is collaborative and ongoing: “There is a governance that underpins the Formula 1 regulations, which means that while the FIA lead the process and guide and carry out the work, we do need to have a level of consensus achieved with the various stakeholders – mainly the teams and the power unit manufacturers – and that is the work we have been carrying out recently.”

He also highlighted the importance of driver input: “But we have also been discussing the matters with the drivers, because ultimately they are sitting in the car, they experience things first‑hand, and it is invaluable to get their input.”

And he cautioned that the refinement process is far from over: “Clearly, when the regulations are new, like we have in 2026, that is a slightly more intense process of discussion than maybe when the regulations have had a few years of maturity.”

“We are all still learning about these regulations; it’s not as if the work is now finished and we can all go on holiday.”
