Active Aero & Overtake Mode - Understanding F1's Updated Regulatory Terminology

The world of Formula 1 has revealed the new terminology that will be used to explain the intricate details of its new 2026 technical rules.

The championship is introducing what is potentially the largest regulation change in its long history starting in 2026, featuring new chassis and engine rules and the compulsory introduction of fully sustainable fuels.

The revised engines, which keep the 1.6-litre V6 configuration, boast a significantly increased electrical capacity, driving key advancements in the aero packages.

During grand prix events, drivers will tactically deploy ERS energy – sometimes even flying laps – to extract the peak result.

Wide-ranging research were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to identify which terms would improve understanding of the main elements of the new regulations.

The stated goal was to make a range of advanced technical aspects of the racing as easy to grasp as possible for the broadest viewership.

Consequently, older technical labels for specific components – such as "alphabetical mode names" for the active aerodynamics – have been discarded in favour of straightforward terms that directly explain the actual function of the system.

What's the New Technology?

According to rule-makers that competitors will have increased agency to make decisions regarding power usage, regeneration, and conservation.

The 2026 rules introduce a range of settings that will be shown on TV overlays to improve the audience's understanding of the race battle.

• Attack Mode: This supersedes the existing Drag Reduction System. It provides a surge of additional ERS power available when a driver is within one second the leading car to assist with an overtaking maneuver.
• Power Mode: This is a manual energy deployment from the hybrid system that can be deployed for overtaking or defending. It provides the driver full engine and battery energy at the push of a button.

Both of these strategic tools will have to be managed carefully, as the overall battery capacity is capped.

• Active Aero: Both the front and rear wings move automatically – spreading on the straights for minimal air resistance and top speed, and sealing in the corners for peak grip.
• Battery Recharge: Drivers can recharge the energy store with energy harvested under braking, or during coasting at the conclusion of a straight or in sections where only limited engine output is required.

Car Design Evolution

The vehicles for the new era will be reduced in size and weight relative to current models, with a car length reduced by 200mm to 3,400mm, car width reduced by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.

Total aerodynamic grip is projected to decrease by approximately fifteen to thirty percent, although constructors will naturally regain performance as they refine their designs.

Aerodynamic drag has been cut by 40%. The vehicles will feature moveable wing elements – front and rear wings will move on the straights to reduce drag and boost top speed and return into place for optimal grip in corners.

Tyres will retain 18-inch rims, but the actual tyres will be reduced in width, by 25 millimetres on the front axle and 30 millimetres on the rear axle.

2026 Engine Regulations

The 2026 engines will have an near-equal balance in energy output by the ICE and the electrical system, a rise from about 20% battery contribution under present rules.

The hybrid system is made less complex through the removal of the complex turbo energy recovery device, the intricate and expensive device that recovered energy from the turbo.

Every car on the grid will be required to run on carbon-neutral fuel, manufactured from biomass or lab-created processes.
