F1 has revealed the official language that will be used to explain the intricate details of its upcoming 2026 rulebook.

The racing series is introducing what is considered the largest technical shift in its competitive history next season, featuring revised car and engine specifications and the required adoption of eco-friendly fuels.

The revised engines, which retain the 1.6-litre V6 configuration, boast a substantially higher electrical capacity, necessitating major innovations in the vehicles' aerodynamic design.

Over a race distance, drivers will strategically manage battery power – including during hot laps – to secure the optimal result.

Wide-ranging research were carried out with a wide range of fans, including dedicated enthusiasts and casual observers, to determine which phrases would aid comprehension of the central aspects of the 2026 changes.

The stated goal was to render a series of complex technical aspects of the competition as accessible as possible for the global fanbase.

Consequently, previous placeholder terms for some systems – such as "alphabetical mode names" for the active aerodynamics – have been abandoned in favor of descriptive names that succinctly convey the real-world effect of the system.

Exploring the New Tech

According to rule-makers that competitors will have more power to choose strategies regarding power usage, regeneration, and efficiency.

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

• Attack Mode: This replaces the existing Drag Reduction System. It provides a surge of additional ERS power available when a car is less than a second the car ahead to execute an overtaking maneuver.
• Boost 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 maximum power at the activation of a control.

Both of these strategic tools will have to be used with calculation, as the overall battery capacity is restricted.

• Adjustable Aero: Both the nose and rear wings move automatically – opening on the high-speed sections for minimal air resistance and increased velocity, and closing in the corners for optimal cornering performance.
• Recharge: The system can recharge the energy store with energy harvested under braking, or during coasting at the end of straights or in sections where only partial power is used.

2026 Car Specifications

The 2026 cars will be more compact and lighter than this year, with a wheelbase reduced by 200mm to 3,400mm, overall width cut by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.

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

Drag has been reduced by 40%. The cars will utilize moveable wing elements – front and rear wings will open on the straight sections to improve speed and boost top speed and return into place for peak handling.

Wheels will continue to use the current rim size, but the rubber compounds will be narrower, by 25mm at the front and 30 millimetres on the rear axle.

Power Unit Revolution

The 2026 engines will have an near-equal balance in horsepower generated by the internal combustion engine and the electrical system, increasing from about 20% battery contribution this year.

The hybrid system is simplified through the removal of the complex turbo energy recovery device, the complicated and costly device that generated electricity from the exhaust turbo.

Every car on the grid will be required to run on 100% sustainable fuel, created from plant-based materials or synthetic industrial processes.
