The world of Formula 1 has revealed the official language that will be used to reference the intricate details of its new 2026 regulations.

The championship is introducing what is potentially the biggest rules overhaul in its competitive history for the 2026 campaign, featuring revised car and engine specifications and the compulsory introduction of 100% sustainable fuels.

The revised engines, which keep the 1.6-litre V6 turbo hybrid, boast a significantly increased electrical capacity, requiring key advancements in the cars' aerodynamics.

Over a race distance, competitors will tactically deploy ERS energy – potentially on qualifying laps – to extract the best performance.

Wide-ranging research were conducted with a mix of viewers, including dedicated enthusiasts and casual observers, to understand which terms would aid comprehension of the central aspects of the new regulations.

The primary aim was to present a range of advanced new areas of the racing as accessible as possible for the global fanbase.

Consequently, previous placeholder terms for some systems – such as "alphabetical mode names" for the moveable wings – have been discarded in preference for intuitive labels that succinctly convey the real-world effect of the innovation.

Exploring the New Tech

According to rule-makers that racers will have increased agency to make decisions regarding energy deployment, energy recovery, and efficiency.

The upcoming changes introduce a series of modes that will be shown on television graphics to enhance the audience's understanding of the race battle.

• Attack Mode: This replaces the present overtaking aid. It provides a surge of additional ERS power available when a competitor is less than a second the vehicle in front to execute an pass.
• Power Mode: This is a driver-operated power boost from the energy recovery system that can be deployed for overtaking or defending. It delivers the pilot full engine and battery energy at the click of a switch.

Both of these crucial modes will have to be used with calculation, as the total energy is restricted.

• Active Aero: Both the car's wings move automatically – opening on the long straight sections for minimal air resistance and top speed, and closing in the bends for maximum downforce.
• Recharge: Drivers can recharge the energy store with energy harvested under braking, or during coasting at the straight's end or in certain corners where only reduced throttle is required.

2026 Car Specifications

The next-generation machines will be reduced in size and weight compared to the 2025 spec, with a distance between axles reduced by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the car weight reduced by 30kg.

Overall downforce is anticipated to be reduced by approximately fifteen to thirty percent, although constructors will inevitably claw this back as they refine their designs.

Aerodynamic drag has been cut by 40%. The cars will employ active aerodynamics – both wings will adjust on the straight sections to reduce drag and increase straightline speed and revert into place for optimal grip in corners.

Wheels will keep the current rim size, but the actual tyres will be slimmer, by a quarter-centimetre on the front and 30mm at the rear.

Power Unit Revolution

The revised hybrid units will have an roughly half-and-half distribution in horsepower generated by the internal combustion engine and the battery and motor, increasing from about 20% battery contribution this year.

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

All vehicles will be required to run on 100% sustainable fuel, produced using plant-based materials or synthetic production methods.
