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

The world of Formula 1 has revealed the simplified terminology that will be used to describe the intricate details of its upcoming 2026 rulebook.

The sport is embarking on what is considered the largest regulation change in its illustrious history starting in 2026, featuring revised car and engine specifications and the mandatory use of eco-friendly fuels.

The new power units, which keep the 1.6-litre V6 configuration, boast a greatly enhanced energy storage, necessitating key advancements in the cars' aerodynamics.

Over a race distance, drivers will tactically deploy ERS energy – sometimes even flying laps – to extract the peak lap time.

Extensive fan consultation were carried out with a diverse audience, including new, casual and core fans, to determine which phrases would make things clearer of the central aspects of the 2026 changes.

The key objective was to make a set of intricate features of the competition as straightforward as possible for the broadest viewership.

Consequently, previous placeholder terms for some systems – such as "modes labelled X and Z" for the moveable wings – have been phased out in favor of straightforward terms that directly explain the primary purpose of the technology.

Key Technical Innovations

According to rule-makers that racers will have increased agency to choose strategies regarding power usage, regeneration, and saving energy.

The new regulations mandate a set of functions that will be shown on TV overlays to improve the viewers' comprehension of the strategic duel.

• Attack Mode: This supersedes the current DRS. It provides a surge of additional ERS power available when a driver is less than a second the car ahead to assist with an overtake.
• Power Mode: This is a on-demand power boost from the energy recovery system that can be utilized during offensive or defensive moves. It delivers the pilot peak output at the click of a switch.

Both of these key functions will have to be used with calculation, as the total energy is capped.

• Active Aero: Both the car's wings move automatically – spreading on the long straight sections for low aerodynamic resistance and higher speed, and closing in the corners for peak grip.
• Recharge: The system can recharge the energy store with regenerative braking, or during coasting at the straight's end or in sections where only partial power is applied.

Car Design Evolution

The vehicles for the new era will be smaller and lighter than this year, with a distance between axles shortened by 200mm to 3,400mm, width reduced by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.

Overall downforce is expected to drop by approximately a significant margin, although squads will undoubtedly recover some as they develop their cars.

Drag has been reduced by 40%. The vehicles will feature adjustable aero systems – both wings will adjust on the straights to reduce drag and increase straightline speed and return into place for peak handling.

Wheels will continue to use 18-inch rims, but the tyres themselves will be reduced in width, by 25mm at the front and 30mm at the rear.

2026 Engine Regulations

The new power units will have an approximate 50-50 split in horsepower generated by the ICE and the electrical system, a rise from about one-fifth electric power this year.

The energy recovery system is streamlined through the elimination of the MGU-H, the sophisticated and pricey device that recovered energy from the turbocharger.

Cars will be mandated to operate on 100% sustainable fuel, created from organic sources or synthetic industrial processes.
