The world of Formula 1 has unveiled the new language that will be used to explain the technical complexities of its upcoming 2026 technical rules.

The sport is embarking on what is arguably the biggest rules overhaul in its illustrious history starting in 2026, featuring revised car and engine specifications and the required adoption of eco-friendly fuels.

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

Over a race distance, competitors will tactically deploy ERS energy – sometimes even qualifying laps – to extract the peak result.

Wide-ranging research were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to understand which phrases would improve understanding of the main elements of the upcoming rules.

The key objective was to present a range of advanced features of the competition as straightforward as possible for the global fanbase.

Consequently, initial designations for specific components – such as "alphabetical mode names" for the adjustable aero – have been abandoned in favor of straightforward terms that succinctly convey the primary purpose of the system.

Exploring the New Tech

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

The upcoming changes feature a series of modes that will be clearly indicated on television graphics to enhance the viewers' comprehension of the on-track action.

• Attack Mode: This replaces the existing Drag Reduction System. It provides a surge of additional ERS power available when a driver is within one second the leading car to execute an overtaking maneuver.
• Boost Mode: This is a on-demand 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 key functions will have to be deployed strategically, as the available electrical charge is restricted.

• Active Aerodynamics: Both the car's wings move automatically – opening on the high-speed sections for low aerodynamic resistance and increased velocity, and closing in the bends for maximum downforce.
• Energy Harvesting: Cars can replenish their battery with power recovered from braking, or during partial power application at the straight's end or in sections where only limited engine output is required.

Car Design Evolution

The next-generation machines will be more compact and lighter relative to current models, with a car length reduced by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.

Cumulative downforce is expected to drop by approximately fifteen to thirty percent, although squads will inevitably claw this back as they optimize their packages.

Air resistance has been slashed by 40%. The vehicles will utilize moveable wing elements – both wings will open on the straight sections to reduce drag and enhance velocity and revert into place for maximum cornering performance.

Pirelli tyres will keep 18-inch wheel rims, but the rubber compounds will be slimmer, by a quarter-centimetre on the front and 30 millimetres on the rear axle.

What's Changing in the Engines?

The 2026 engines will have an approximate 50-50 split in energy output by the petrol engine and the battery and motor, increasing from about 20% electrical this year.

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

Every car on the grid will be required to run on carbon-neutral fuel, produced using organic sources or synthetic production methods.
