FIA considering drastic engine power restrictions for Formula 1 2026
The FIA could take an unprecedented step by introducing restrictions on engine power for the 2026 Formula 1 season. The aim is clear: to maintain safety on circuits where the new generation of cars might otherwise reach dangerously high speeds. The governing body is studying solutions that could fundamentally change how racing unfolds on certain tracks, with the focus firmly on safety and the balance between performance and risk.
The next regulatory cycle will bring cars and engines that are very different from what Formula 1 fans are accustomed to today. With radically revised hybrid power units and a stronger emphasis on electrification, teams and drivers will face new challenges that may be difficult to manage, especially during the early stages. Among the most critical concerns is the enormous power output expected from the engines debuting in 2026. The FIA has already expressed worries about how these new machines might behave on specific circuits that combine long straights with limited safety margins.
400 km/h speeds raise concerns
In recent weeks, early data and estimates about the 2026 cars have started to emerge. Mercedes team principal Toto Wolff even mentioned that in some scenarios, the cars could approach an astonishing 400 km/h, speeds that Formula 1 has never consistently seen before. These figures contradict the initial forecasts, which suggested that the next-generation cars would actually be slower than today’s models due to heavier batteries and more restrictive technical rules.
Instead, the combination of powerful hybrid engines and aerodynamic changes might create a situation where top speeds on some tracks could exceed the safety thresholds currently considered acceptable. This has led the FIA to explore measures that would prevent cars from running at full throttle for extended periods.
The FIA’s plan to limit full-throttle usage
According to reports from the German outlet Auto Motor und Sport (AMuS), the FIA is evaluating a set of extraordinary solutions to be applied on certain circuits. One of the key measures under consideration is regulating the amount of time drivers can remain at “full gas” – maximum engine deployment – on different tracks. Essentially, the FIA would introduce limits on how long the power unit can operate at peak capacity across a lap.
AMuS revealed potential figures for three key circuits: at Melbourne, cars could run full throttle for 4,630 meters out of the 5,278-meter lap; at Monza, the so-called Temple of Speed, the restriction would be set at 4,218 meters out of 5,793; while in Monte Carlo, one of the slowest and most technical venues on the calendar, the limit could be just 1,388 meters out of 3,337.
Special limits for Monaco and Singapore
The Monaco Grand Prix appears to be one of the circuits most affected by these potential changes. Along with Singapore, the Principality could see the introduction of a specific power restriction known as “Rev1.” This measure would reduce engine output in certain parts of the lap, preventing the cars from reaching excessive speeds that would be unsafe given the narrow streets, minimal run-off areas, and tight corners of these city circuits.
On high-speed circuits such as Monza, Silverstone, or Spa-Francorchamps, the approach would be slightly different. Instead of a constant reduction in power, the FIA may apply temporary restrictions designed to maintain a balance between outright performance and driver safety. These measures would ensure that cars do not generate extreme speed differentials that could compromise both racing quality and circuit safety standards.
Work in progress, with driver feedback crucial
At this stage, the proposals are still embryonic and far from finalized. The FIA will need weeks – if not months – to refine the regulations and to consider input from teams, engineers, and especially drivers. Pilot feedback will play a crucial role in shaping how these rules are applied in practice, since only they can fully assess how the new cars behave at the limit under real conditions.
What is certain is that Formula 1 is heading towards one of the most radical technical shifts in its history, and with it comes an urgent need to carefully balance innovation with safety. While the 2026 power units promise to deliver unprecedented performance levels, the FIA’s challenge will be to ensure that this performance does not compromise the well-being of the drivers or the integrity of the racing itself.
The full regulations are expected to evolve throughout 2025 as more data becomes available from simulations and early prototypes. For now, fans can expect discussions around safety, speed, and power management to remain at the forefront of Formula 1’s journey into its next era.
