Overtake Mode & Active Aero - Explaining F1's Updated Technical Language

The world of Formula 1 has introduced the new language that will be used to explain the technical complexities of its upcoming 2026 technical rules.

The racing series is implementing what is potentially the most significant technical shift in its long history starting in 2026, featuring new chassis and engine rules and the required adoption of fully sustainable fuels.

The revised engines, which retain the hybrid V6 layout, boast a greatly enhanced electrical capacity, requiring key advancements in the cars' aerodynamics.

Over a race distance, drivers will carefully oversee battery power – including during flying laps – to achieve the best performance.

Extensive fan consultation were undertaken with a mix of viewers, including long-time followers and newcomers, to determine which terminology would make things clearer of the main elements of the 2026 changes.

The stated goal was to present a range of advanced technical aspects of the competition as straightforward as possible for the global fanbase.

Consequently, previous placeholder terms for some systems – such as "x-mode and z-mode" for the active aerodynamics – have been discarded in favor of intuitive labels that directly explain the real-world effect of the technology.

Key Technical Innovations

The FIA states that drivers will have more power to make decisions regarding power usage, harvesting, and saving energy.

The new regulations introduce a range of settings that will be clearly indicated on television graphics to aid the audience's understanding of the on-track action.

• Passing Mode: This supersedes the existing Drag Reduction System. It provides a short boost of battery power available when a competitor is within one second the vehicle in front to facilitate an pass.
• Extra Push Mode: This is a on-demand power boost from the energy recovery system that can be deployed for attack or defence. It provides the driver maximum power at the click of a switch.

Both of these key functions will have to be deployed strategically, as the available electrical charge is strictly limited.

• Adjustable Aero: Both the nose and rear wings change configuration – opening on the high-speed sections for low aerodynamic resistance and higher speed, and closing in the corners for peak grip.
• Recharge: Drivers can harvest energy with energy harvested under braking, or during partial power application at the straight's end or in corners where only limited engine output is required.

What's Changing on the Cars?

The next-generation machines will be reduced in size and weight relative to current models, with a distance between axles cut by 200mm to 3,400mm, overall width narrowed by 100mm – down to 1,900mm – and the minimum weight decreased by 30kg.

Cumulative downforce is projected to decrease by approximately a significant margin, although squads will undoubtedly recover some as they develop their cars.

Air resistance has been cut by 40%. The cars will employ moveable wing elements – both wings will adjust on the straights to improve speed and boost top speed and return into place for maximum cornering performance.

Pirelli tyres will continue to use the current rim size, but the tyres themselves will be slimmer, by 25 millimetres on the front axle and three centimetres on the rear.

Power Unit Revolution

The new power units will have an roughly half-and-half distribution in horsepower generated by the ICE and the electrical system, up from about one-fifth electric power this year.

The energy recovery system is simplified through the elimination of the Motor Generator Unit – Heat, the complicated and costly device that generated electricity from the turbo.

Every car on the grid will be required to run on carbon-neutral fuel, created from plant-based materials or synthetic production methods.
