Formula 1 has introduced the simplified language that will be used to explain the intricate details of its upcoming 2026 rulebook.

The sport is implementing what is arguably the biggest rules overhaul in its illustrious history next season, featuring new chassis and engine rules and the compulsory introduction of fully sustainable fuels.

The revised engines, which retain the hybrid V6 layout, boast a greatly enhanced energy storage, driving significant developments in the cars' aerodynamics.

Throughout races, pilots will carefully oversee ERS energy – including during qualifying laps – to achieve the optimal performance.

Broad surveys were carried out with a wide range of fans, including new, casual and core fans, to determine which terminology would improve understanding of the main elements of the 2026 changes.

The key objective was to make a series of complex features of the racing as straightforward as possible for the global fanbase.

Consequently, older technical labels for certain devices – such as "alphabetical mode names" for the moveable wings – have been abandoned in preference for descriptive names that clearly indicate the real-world effect of the technology.

Key Technical Innovations

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

The upcoming changes introduce a set of functions that will be visually displayed on TV overlays to improve the audience's understanding of the race battle.

• Attack Mode: This supersedes the current DRS. It provides a burst of extra electrical energy accessible when a competitor is within one second the car ahead to facilitate an overtake.
• Extra Push Mode: This is a on-demand power boost from the hybrid system that can be deployed for offensive or defensive moves. It delivers the driver peak output at the push of a button.

Both of these crucial modes will have to be deployed strategically, as the overall battery capacity is restricted.

• Active Aero: Both the nose and rear wings adjust their angles – opening on the high-speed sections for low aerodynamic resistance and top speed, and angling down in the turns for maximum downforce.
• Recharge: Drivers can recharge the energy store with power recovered from braking, or during partial power application at the conclusion of a straight or in corners where only partial power is required.

What's Changing on the Cars?

The 2026 cars will be more compact and lighter compared to the 2025 spec, with a wheelbase reduced by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the minimum weight reduced by 30kg.

Cumulative downforce is anticipated to be reduced by approximately a significant margin, although teams will undoubtedly recover some as they refine their designs.

Aerodynamic drag has been slashed by 40%. The cars will employ adjustable aero systems – both wings will adjust on the straight sections to improve speed and enhance velocity and return into place for peak handling.

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

2026 Engine Regulations

The 2026 engines will have an approximate 50-50 split in energy output by the internal combustion engine and the battery and motor, increasing from about 20% electrical under present rules.

The energy recovery system is made less complex through the elimination of the complex turbo energy recovery device, the complicated and costly unit that harvested power from the turbo.

Cars will be mandated to operate on carbon-neutral fuel, produced using biomass or synthetic production methods.
