The world of Formula 1 has revealed the official vocabulary that will be used to explain the technical complexities of its upcoming 2026 regulations.

The championship is implementing what is potentially the largest rules overhaul in its long history next season, featuring new chassis and engine rules and the compulsory introduction of eco-friendly fuels.

The updated 1.6-litre V6 turbo hybrids, which retain the hybrid V6 layout, boast a greatly enhanced electrical capacity, necessitating significant developments in the aero packages.

Throughout races, drivers will strategically manage battery power – potentially on flying laps – to achieve the peak performance.

Broad surveys were undertaken with a mix of viewers, including new, casual and core fans, to determine which terms would make things clearer of the central aspects of the new regulations.

The primary aim was to present a series of complex new areas of the sport as accessible as possible for the broadest viewership.

Consequently, initial designations for certain devices – such as "x-mode and z-mode" for the active aerodynamics – have been phased out in favour of intuitive labels that clearly indicate the actual function of the innovation.

Exploring the New Tech

The FIA states that racers will have greater control to determine tactics regarding battery management, regeneration, and conservation.

The upcoming changes feature a range of settings that will be shown on television graphics to improve the viewers' comprehension of the strategic duel.

• Attack Mode: This takes over from the existing Drag Reduction System. It provides a short boost of battery power available when a competitor is close behind the car ahead to execute an overtake.
• Power Mode: This is a on-demand battery discharge from the ERS that can be used in attack or defence. It provides the pilot peak output at the push of a button.

Both of these crucial modes will have to be deployed strategically, as the overall battery capacity is restricted.

• Active Aero: Both the front and rear wings adjust their angles – spreading on the long straight sections for low aerodynamic resistance and higher speed, and closing in the corners for optimal cornering performance.
• Battery Recharge: The system can harvest energy with regenerative braking, or during partial power application at the straight's end or in sections where only partial power is applied.

What's Changing on the Cars?

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

Cumulative downforce is anticipated to be reduced by approximately fifteen to thirty percent, although constructors will naturally regain performance as they develop their cars.

Drag has been cut by 40%. The cars will utilize adjustable aero systems – front and rear wings will adjust on the straight sections to reduce drag and boost top speed and revert into place for peak handling.

Tyres will continue to use 18-inch rims, but the rubber compounds will be reduced in width, by 25mm at the front and 30mm at the rear.

What's Changing in the Engines?

The 2026 engines will have an roughly half-and-half distribution in power produced by the ICE and the ERS, a rise from about 20% battery contribution under present rules.

The hybrid system is streamlined through the removal of the MGU-H, the intricate and expensive component that generated electricity from the turbo.

Every car on the grid will be obliged to compete on fully sustainable fuel, manufactured from organic sources or lab-created processes.
