The Federação Internacional of Automobilismo (FIA) has made official one of the most radical change packages in the history of the Redução of Arrasto).

The central objective of the reformulation is to create a more competitive show and increase opportunities for overtaking. With the introduction of innovative technologies, the category seeks not only to improve performance on the track, but also to reinforce its commitment to sustainability, through the use of 100% synthetic fuels and greater dependence on electrical energy.

In response to a long-standing request from drivers, the new single-seaters will be smaller and lighter. The 30-kilo reduction in minimum weight and the reduction in overall car dimensions are measures designed to facilitate wheel-to-wheel competition, especially on narrower street circuits, by making vehicles less susceptible to the negative effects of turbulent air generated by the car in front.

The end of DRS and the arrival of active aerodynamics

The most significant change to the regulations is the implementation of active aerodynamics, which retires DRS as we know it. The new system will allow drivers to adjust the angle of the front and rear wings during the race, switching between two distinct modes. The default mode, called “Z-Mode”, will offer high downforce to maximize cornering grip. Já “X-Mode”, a low-drag mode, will be activated on the straights to increase maximum speed.

This technology will be available to all drivers in pre-determined zones on the circuit, regardless of the distance to the car in front, unlike the current DRS. Managing these modes will add a new layer of strategy and skill, requiring drivers to optimize their car’s aerodynamic configuration several times per lap to balance cornering performance and straightaway speed, making driving more demanding and tactical.

Manual Override: the new overdrive button

To complement active aerodynamics, the FIA ​​has introduced “Manual Override Mode”, a feature that will act as an extra boost of electrical power to facilitate overtaking. Este system will allow the driver behind to use the maximum power of 350 kW of his power unit (MGU-K) for longer than the car in front.

The dynamics will work as follows: the electrical energy of the leading car will begin to be gradually reduced from 290 km/h, while the following car can activate manual mode to maintain maximum power until reaching 337 km/h. Essa momentary speed difference will create the necessary window of opportunity for the overtaking maneuver, promising more intense and strategic duels on the straights.

Engines and fuel: the focus on sustainability

The power units will also undergo a complete overhaul. The complex and expensive MGU-H (heat energy recovery unit) will be removed, simplifying the engine architecture and reducing costs, which was a key factor in attracting new manufacturers like Audi and ensuring the return of the Honda.

Power will be divided more evenly between the internal combustion engine and the electrical system. The energy coming from the MGU-K will be almost tripled, jumping from the current 120 kW to 350 kW, meaning that almost 50% of the car’s total power will come from electrical sources.

One of the pillars of the new era of Fórmula 1 is the commitment to the environment. From 2026 onwards, the use of 100% sustainable fuels, developed in the laboratory and with zero carbon emissions, will be mandatory. Esta measure aligns the sport with global sustainability goals and serves as a platform for the development of technologies that could be applied to street cars in the future.

Lighter and more agile cars for close races

The new regulations establish a significant reduction in the weight and dimensions of cars. The minimum weight will drop from 798 kg to 768 kg, making single-seaters more responsive and less taxing on the tires.

The wheelbase will be reduced from 3,600 mm to 3,400 mm, and the width will increase from 2,000 mm to 1,900 mm. Essas changes will help cars to be more agile and easier to maneuver in tight spaces.

Furthermore, the FIA ​​sought to simplify the design of the floor and diffusers to reduce the phenomenon of “dirty air”, the turbulence that impairs the performance of the car behind. With less reliance on clean air, pilots will be able to follow each other more closely, increasing the chances of head-to-head battles.

This philosophy of an “agile” car was developed to create more exciting races, where the driver’s ability in head-to-head competitions becomes an even more determining factor in the final result of the races.

Security as a fundamental pillar of the new rules

Despite the search for lighter and faster cars, safety remains the FIA’s top priority. The 2026 regulation introduces more robust impact structures and rigorous new safety tests. The front crash structure will undergo a two-phase test, and side intrusion protection has been significantly improved to provide greater safety in side collisions. The “santantônio” structures were also reinforced to withstand loads of up to 20G, preventing failures such as those seen in recent accidents. Rear safety lights will be brighter and integrated into the wings, ensuring better visibility in wet or spray conditions, a point of concern consistently raised by pilots. Essas improvements were designed to integrate with the new chassis without compromising weight reduction objectives, showing the engineering advancement in the category.

Paddock reactions and expectations

In the Fórmula 1 environment, the announcement of the new rules generated a wave of optimism mixed with a dose of caution. Chefes team and engineers recognize the enormous technical challenge they will face in designing and building competitive cars under such different regulations.

Teams are already dedicating thousands of hours in simulations to decipher the secrets of new aerodynamics and energy management, aware that whoever interprets the rules most intelligently could gain a crucial advantage at the beginning of this new era.

The impact on fans and the show

All of these changes were designed with one audience in mind: the fans. The promise is of a more unpredictable sport, with less procedural races and more genuine battles for position. The combination of more agile cars, new ways of overtaking and greater emphasis on driver skill has the potential to deliver an even more captivating and exciting sporting spectacle from 2026 onwards.
