Active Aero & Overtake Mode - Understanding F1's New Technical Language

Formula 1 has introduced the official language that will be used to reference the technical complexities of its revolutionary 2026 regulations.

The sport is introducing what is considered the most significant rules overhaul in its illustrious history for the 2026 campaign, featuring fresh chassis and power unit regulations and the compulsory introduction of fully sustainable fuels.

The revised engines, which keep the hybrid V6 layout, boast a significantly increased battery power, necessitating significant developments in the cars' aerodynamics.

Throughout races, drivers will strategically manage electrical energy – potentially on flying laps – to extract the optimal lap time.

Wide-ranging research were undertaken with a diverse audience, including long-time followers and newcomers, to determine which phrases would make things clearer of the key features of the upcoming rules.

The stated goal was to present a set of intricate features of the sport as straightforward as possible for the broadest viewership.

Consequently, older technical labels for specific components – such as "modes labelled X and Z" for the adjustable aero – have been phased out in favor of descriptive names that succinctly convey the actual function of the system.

What's the New Technology?

Regulators explain that drivers will have more power to choose strategies regarding power usage, energy recovery, and conservation.

The upcoming changes introduce a range of settings that will be visually displayed on broadcast screens to aid the audience's understanding of the strategic duel.

• Passing Mode: This replaces the current DRS. It provides a surge of additional ERS power available when a car is less than a second the leading car to facilitate an overtake.
• Extra Push Mode: This is a driver-operated power boost from the ERS that can be deployed for attack or defence. It provides the driver full engine and battery energy at the click of a switch.

Both of these crucial modes will have to be used with calculation, as the total energy is restricted.

• Adjustable Aero: Both the car's wings change configuration – flattening on the high-speed sections for low aerodynamic resistance and higher speed, and angling down in the bends for peak grip.
• Battery Recharge: Cars can replenish their battery with regenerative braking, or during throttle lift at the end of straights or in sections where only reduced throttle is required.

What's Changing on the Cars?

The next-generation machines will be reduced in size and weight compared to the 2025 spec, with a car length shortened by 200mm to 3,400mm, car width reduced by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Total aerodynamic grip is anticipated to be reduced by approximately fifteen to thirty percent, although squads will inevitably claw this back as they develop their cars.

Aerodynamic drag has been slashed by 40%. The cars will employ adjustable aero systems – front and rear wings will move on the straight sections to improve speed and boost top speed and return into place for maximum cornering performance.

Wheels will retain the current rim size, but the rubber compounds will be narrower, 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 energy output by the petrol engine and the ERS, a rise from about 20% battery contribution in the current formula.

The ERS setup is simplified through the elimination of the Motor Generator Unit – Heat, the sophisticated and pricey component that generated electricity from the exhaust turbo.

Cars will be mandated to operate on 100% sustainable fuel, created from plant-based materials or synthetic industrial processes.
