We're finally here, after the return of ground effect single-seaters in 2022, Formula 1 is preparing to experience a new era. On the eve of the Canadian Grand Prix weekend FIA and F1 have finally revealed the new regulations which will debut in 2026. A regulation that in this new cycle will revolutionize the Power Units but also the single-seaters, with innovations both in terms of chassis and aerodynamics. Let's see all the news presented by the FIA, which has also published the first renderings of the 2026 single-seaters.
The long-awaited innovations of the 2026 regulation
Some information regarding these regulations was already known. In particular those relating to the new Power Units, with the elimination of the MGU-H deemed too complex and expensive. In fact, it will be up to the MGU-K to compensate for this loss, with an increase in electrical power. Another aspect linked to the new Power Units concerns the use of sustainable fuels. In essence, therefore, less expenses and fewer emissions.
But the news won't just stop at the Power Units. In fact, the single-seaters will undergo changes that will also have a great impact on aerodynamics. An important change is linked to the Venturi channels which will disappear, and the introduction of active aerodynamics, resulting in the end of the DRS. FIA and F1 have also reiterated their desire to reduce the volume and dimensions of the single-seaters in order to facilitate overtaking and battles on the track.
Active aerodynamics and the disappearance of DRS
The new overtaking mode is called MOS (Manual Override System), which will replace DRS. Specifically, while the power of a leading car reduces after 290 km/h, reaching zero at 355 km/h, the following car will benefit from the MGUK Override which provides 350 kW up to 337 km/h.
The front wing will have two active flaps and the rear wing will consist of three elements with the aim of having greater balance between the front and rear. The activation mode of this active system also changes since there will be no requirement to be within one second of the previous car to activate 'X mode' in the areas where it will be permitted.
In a statement the FIA has therefore listed the main elements of the 2026 regulation, relating to Power Unit, chassis, aerodynamics, safety and sustainability:
At the center of the 2026 Technical Regulations is the concept of "agility", to improve driveability and make races more competitive
- The 2026 cars will be narrower, shorter and 30kg lighter than the current generation F1, improving efficiency and handling.
- The redesigned Power Units are based on the most efficient engines in the world, with almost 300% more battery power and an even split between internal combustion and electrical energy.
- The single-seaters will have 30% less downforce and 55% less drag
- Active aerodynamics to meet the energy management requirements of the new Power Units
- Introduction of two new operating modes of active aerodynamics: “Z-Mode” and “X-Mode”. Z Mode will be the “standard” position with a lot of downforce, which will be used when cornering. X Mode will be the low downforce position, which will be used on the straight.
- A two-element active rear wing flap will be implemented
- There will no longer be "gull wings" above the wheels
- Greater overtaking opportunities thanks to the new manual override mode which allows greater use of electric energy for the car following
- Record number of six powertrain manufacturers: Ferrari, Mercedes, Alpine, Honda, Audi and Red Bull Ford Powertrains commit to participate in F1 from 2026.
- The 2026 cars will be powered by 100% sustainable fuel
- Greater safety thanks to more robust structures and even more stringent tests
