The world of Formula 1 has unveiled the simplified terminology that will be used to explain the intricate details of its upcoming 2026 regulations.

The racing series is introducing 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 updated 1.6-litre V6 turbo hybrids, which maintain the 1.6-litre V6 turbo hybrid, boast a significantly increased battery power, driving major innovations in the cars' aerodynamics.

Over a race distance, pilots will tactically deploy ERS energy – sometimes even hot laps – to secure the optimal lap time.

Wide-ranging research were carried out with a wide range of fans, including dedicated enthusiasts and casual observers, to identify which terminology would improve understanding of the main elements of the new regulations.

The key objective was to make a set of intricate new areas of the racing as accessible as possible for the widest audience.

Consequently, initial designations for specific components – such as "alphabetical mode names" for the moveable wings – have been abandoned in favor of straightforward terms that directly explain the actual function of the innovation.

Key Technical Innovations

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

The 2026 rules mandate a set of functions that will be shown on television graphics to aid the fans' insight of the on-track action.

• Passing Mode: This replaces the existing Drag Reduction System. It provides a surge of additional ERS power available when a car is within one second the car ahead to execute an overtaking maneuver.
• Extra Push Mode: This is a on-demand energy deployment from the hybrid system that can be used in overtaking or defending. It grants the driver full engine and battery energy at the click of a switch.

Both of these strategic tools will have to be managed carefully, as the available electrical charge is restricted.

• Active Aero: Both the front and rear wings move automatically – spreading on the long straight sections for reduced drag and top speed, and sealing in the bends for peak grip.
• Energy Harvesting: 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 required.

What's Changing on the Cars?

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

Cumulative downforce is projected to decrease by approximately fifteen to thirty percent, although constructors will inevitably claw this back as they develop their cars.

Air resistance has been reduced by 40%. The cars will feature active aerodynamics – front and rear wings will move on the straights to improve speed and enhance velocity and click back into place for maximum cornering performance.

Wheels will keep the current rim size, but the rubber compounds will be slimmer, by a quarter-centimetre on the front and 30 millimetres on the rear axle.

Power Unit Revolution

The new power units will have an approximate 50-50 split in horsepower generated by the petrol engine and the ERS, up from about 20% battery contribution this year.

The energy recovery system is simplified through the elimination of the complex turbo energy recovery device, the sophisticated and pricey device that harvested power from the exhaust turbo.

Every car on the grid will be required to run on carbon-neutral fuel, manufactured from plant-based materials or synthetic production methods.
