The world of Formula 1 has introduced the official terminology that will be used to explain the intricate details of its new 2026 rulebook.

The racing series is embarking on what is arguably the biggest regulation change in its long history starting in 2026, featuring new chassis and engine rules and the compulsory introduction of eco-friendly fuels.

The new power units, which maintain the hybrid V6 layout, boast a greatly enhanced battery power, necessitating major innovations in the aero packages.

Throughout races, pilots will carefully oversee ERS energy – sometimes even flying laps – to extract the best lap time.

Broad surveys were conducted with a diverse audience, including new, casual and core fans, to identify which phrases would improve understanding of the central aspects of the new regulations.

The stated goal was to make a series of complex features of the competition as easy to grasp as possible for the global fanbase.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the moveable wings – have been phased out in favor of descriptive names that clearly indicate the primary purpose of the system.

Key Technical Innovations

The FIA states that drivers will have more power to choose strategies regarding battery management, regeneration, and saving energy.

The new regulations mandate a series of modes that will be clearly indicated on television graphics to improve the audience's understanding of the race battle.

• Overtake Mode: This replaces the current DRS. It provides a burst of extra electrical energy available when a driver is less than a second the car ahead to execute an overtaking maneuver.
• Extra Push Mode: This is a manual power boost from the hybrid system that can be used in offensive or defensive moves. It delivers the driver peak output at the push of a button.

Both of these key functions will have to be used with calculation, as the overall battery capacity is capped.

• Active Aero: Both the car's wings change configuration – opening on the high-speed sections for reduced drag and increased velocity, and angling down in the corners for optimal cornering performance.
• Battery 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 certain corners where only partial power is applied.

Car Design Evolution

The 2026 cars will be more compact and lighter relative to current models, with a car length cut by 200mm to 3,400mm, width reduced by 100mm – down to 1,900mm – and the car weight lowered by 30kg.

Cumulative downforce is projected to decrease by approximately 15-30%, although teams will undoubtedly recover some as they refine their designs.

Air resistance has been cut by 40%. The vehicles will utilize adjustable aero systems – front and rear wings will move on the straight sections to cut resistance and enhance velocity and return into place for optimal grip in corners.

Wheels will continue to use the current rim size, but the actual tyres will be reduced in width, by 25 millimetres on the front axle and 30 millimetres on the rear axle.

Power Unit Revolution

The 2026 engines will have an roughly half-and-half distribution in horsepower generated by the ICE and the battery and motor, increasing from about 20% battery contribution under present rules.

The ERS setup is streamlined through the removal of the Motor Generator Unit – Heat, the intricate and expensive device that generated electricity from the turbocharger.

Cars will be mandated to operate on carbon-neutral fuel, manufactured from biomass or lab-created processes.
