The world of Formula 1 has introduced the simplified terminology that will be used to explain the advanced features of its new 2026 rulebook.

The sport is introducing what is potentially the largest regulation change in its illustrious history next season, featuring fresh chassis and power unit regulations and the required adoption of eco-friendly fuels.

The updated 1.6-litre V6 turbo hybrids, which keep the hybrid V6 layout, boast a significantly increased battery power, requiring significant developments in the aero packages.

Throughout races, pilots will carefully oversee electrical energy – potentially on qualifying laps – to secure the optimal result.

Broad surveys were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which terms would aid comprehension of the main elements of the new regulations.

The key objective was to render a set of intricate features of the competition as accessible as possible for the global fanbase.

Consequently, initial designations for certain devices – such as "alphabetical mode names" for the adjustable aero – have been discarded in favor of intuitive labels that clearly indicate the actual function of the technology.

Exploring the New Tech

According to rule-makers that drivers will have greater control to make decisions regarding battery management, regeneration, and efficiency.

The upcoming changes mandate a range of settings that will be visually displayed on broadcast screens to aid the viewers' comprehension of the on-track action.

• Passing Mode: This replaces the existing Drag Reduction System. It provides a burst of extra electrical energy available when a competitor is less than a second the vehicle in front to facilitate an overtaking maneuver.
• Power Mode: This is a on-demand battery discharge from the energy recovery system that can be utilized during attack or defence. It grants the pilot full engine and battery energy at the activation of a control.

Both of these strategic tools will have to be used with calculation, as the available electrical charge is restricted.

• Active Aero: Both the front and rear wings move automatically – opening on the straights for low aerodynamic resistance and higher speed, and closing in the corners for maximum downforce.
• Recharge: Drivers can recharge the energy store with power recovered from braking, or during coasting at the conclusion of a straight or in sections where only reduced throttle is used.

What's Changing on the Cars?

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

Overall downforce is projected to decrease by approximately a significant margin, although squads will inevitably claw this back as they develop their cars.

Aerodynamic drag has been reduced by 40%. The vehicles will feature moveable wing elements – front and rear wings will move on the straights to cut resistance and enhance velocity and return into place for maximum cornering performance.

Pirelli tyres will retain the current rim size, but the rubber compounds will be narrower, by 25 millimetres on the front axle and 30mm at the rear.

What's Changing in the Engines?

The 2026 engines will have an roughly half-and-half distribution in energy output by the petrol engine and the electrical system, up from about one-fifth electric power this year.

The energy recovery system is made less complex through the removal of the Motor Generator Unit – Heat, the intricate and expensive device that generated electricity from the exhaust turbo.

Cars will be obliged to compete on 100% sustainable fuel, manufactured from biomass or synthetic production methods.
