Active Aero & Overtake Mode - Explaining F1's New Technical Jargon

Conceptual image of a future Formula 1 car

The 2026 Formula 1 cars are set to be lighter, more agile and sustainable compared to current models.

The world of Formula 1 has unveiled the simplified vocabulary that will be used to describe the advanced features of its new 2026 regulations.

The racing series is introducing what is arguably the most significant rules overhaul in its competitive history starting in 2026, featuring revised car and engine specifications and the compulsory introduction of 100% sustainable fuels.

The revised engines, which keep the hybrid V6 layout, boast a substantially higher electrical capacity, driving significant developments in the aero packages.

Throughout races, pilots will strategically manage ERS energy – sometimes even flying laps – to extract the optimal performance.

Extensive fan consultation were undertaken with a diverse audience, including new, casual and core fans, to understand which phrases would make things clearer of the central aspects of the new regulations.

The stated goal was to present a set of intricate technical aspects of the racing as easy to grasp as possible for the broadest viewership.

Consequently, previous placeholder terms for specific components – such as "x-mode and z-mode" for the active aerodynamics – have been discarded in favour of descriptive names that succinctly convey the real-world effect of the innovation.

Key Technical Innovations

The FIA states that competitors will have increased agency to determine tactics regarding battery management, energy recovery, and conservation.

The 2026 rules introduce a range of settings that will be visually displayed on TV overlays to enhance the viewers' comprehension of the on-track action.

  • Attack Mode: This supersedes the current DRS. It provides a burst of extra electrical energy accessible when a competitor is within one second the leading car to facilitate an overtake.
  • Power Mode: This is a on-demand battery discharge from the ERS that can be used in attack or defence. It grants the pilot full engine and battery energy at the activation of a control.

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

  • Active Aero: Both the front and rear wings move automatically – flattening on the high-speed sections for reduced drag and increased velocity, and sealing in the corners for maximum downforce.
  • Battery Recharge: Cars can harvest energy with regenerative braking, or during coasting at the straight's end or in certain corners where only reduced throttle is used.

What's Changing on the Cars?

The next-generation machines will be more compact and lighter compared to the 2025 spec, with a car length cut by 200mm to 3,400mm, width reduced by 100mm – down to 1,900mm – and the car weight reduced 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.

Air resistance has been reduced by 40%. The cars will feature adjustable aero systems – both wings will open on the straight sections to reduce drag and increase straightline speed and click back into place for maximum cornering performance.

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

2026 Engine Regulations

The 2026 engines will have an approximate 50-50 split in horsepower generated by the ICE and the ERS, up from about one-fifth electric power in the current formula.

The energy recovery system is streamlined through the elimination of the complex turbo energy recovery device, the sophisticated and pricey component that recovered energy from the turbo.

Every car on the grid will be obliged to compete on carbon-neutral fuel, produced using biomass or synthetic industrial processes.
