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

Formula 1 has introduced the new vocabulary that will be used to reference the intricate details of its new 2026 technical rules.

The sport is implementing what is arguably the most significant regulation change in its illustrious history starting in 2026, featuring new chassis and engine rules and the required adoption of 100% sustainable fuels.

The revised engines, which retain the hybrid V6 layout, boast a greatly enhanced battery power, requiring significant developments in the aero packages.

Throughout races, pilots will carefully oversee electrical energy – including during flying laps – to secure the best result.

Broad surveys were undertaken with a diverse audience, including new, casual and core fans, to determine which terminology would make things clearer of the central aspects of the 2026 changes.

The stated goal was to present a range of advanced features of the racing as accessible as possible for the global fanbase.

Consequently, initial designations for specific components – such as "alphabetical mode names" for the active aerodynamics – have been phased out in favor of intuitive labels that clearly indicate the real-world effect of the technology.

What's the New Technology?

The FIA states that drivers will have greater control to choose strategies regarding power usage, energy recovery, and conservation.

The 2026 rules mandate a series of modes that will be clearly indicated on television graphics to improve the fans' insight of the race battle.

• Passing Mode: This takes over from the current DRS. It provides a surge of additional ERS power deployable when a car is close behind the leading car to facilitate an overtaking maneuver.
• Extra Push Mode: This is a manual power boost from the ERS that can be used in offensive or defensive moves. It delivers the driver full engine and battery energy at the click of a switch.

Both of these crucial modes will have to be managed carefully, as the available electrical charge is restricted.

• Adjustable Aero: Both the front and rear wings adjust their angles – opening on the long straight sections for low aerodynamic resistance and increased velocity, and sealing in the corners for maximum downforce.
• Recharge: The system can recharge the energy store with regenerative braking, or during partial power application at the end of straights or in certain corners where only limited engine output is used.

What's Changing on the Cars?

The 2026 cars will be more compact and lighter relative to current models, with a car length reduced by 200mm to 3,400mm, overall width narrowed 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 inevitably claw this back as they optimize their packages.

Aerodynamic drag has been slashed by 40%. The vehicles will employ moveable wing elements – both wings will move on the straights to cut resistance and boost top speed and click back into place for peak handling.

Tyres will continue to use 18-inch rims, but the tyres themselves will be slimmer, by 25mm at the front and 30 millimetres on the rear axle.

What's Changing in the Engines?

The revised hybrid units will have an approximate 50-50 split in horsepower generated by the petrol engine and the battery and motor, a rise from about 20% battery contribution under present rules.

The energy recovery system is simplified through the removal of the MGU-H, the sophisticated and pricey component that generated electricity from the exhaust turbo.

Every car on the grid will be mandated to operate on carbon-neutral fuel, produced using organic sources or lab-created processes.
