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

The racing series is implementing what is arguably the biggest regulation change in its illustrious history for the 2026 campaign, featuring revised car and engine specifications and the required adoption of 100% sustainable fuels.

The revised engines, which keep the 1.6-litre V6 configuration, boast a greatly enhanced battery power, driving major innovations in the cars' aerodynamics.

Throughout races, drivers will carefully oversee battery power – sometimes even qualifying laps – to secure the peak result.

Wide-ranging research were conducted with a diverse audience, including new, casual and core fans, to understand which terms would improve understanding of the key features of the upcoming rules.

The key objective was to render a set of intricate features of the racing as easy to grasp as possible for the broadest viewership.

Consequently, older technical labels for specific components – such as "x-mode and z-mode" for the active aerodynamics – have been phased out in preference for descriptive names that clearly indicate the real-world effect of the technology.

Exploring the New Tech

According to rule-makers that competitors will have more power to choose strategies regarding battery management, energy recovery, and efficiency.

The new regulations feature a set of functions that will be clearly indicated on TV overlays to improve the fans' insight of the on-track action.

• Passing Mode: This takes over from the present overtaking aid. It provides a burst of extra electrical energy available when a car is within one second the vehicle in front to assist with an overtake.
• Boost Mode: This is a on-demand energy deployment from the ERS that can be used in attack or defence. It delivers the driver full engine and battery energy at the push of a button.

Both of these strategic tools will have to be used with calculation, as the available electrical charge is capped.

• Active Aero: Both the front and rear wings move automatically – spreading on the straights for low aerodynamic resistance and top speed, and sealing in the bends for peak grip.
• Battery Recharge: Drivers can harvest energy with energy harvested under braking, or during throttle lift at the end of straights or in corners where only reduced throttle is used.

What's Changing on the Cars?

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

Total aerodynamic grip is anticipated to be reduced by approximately a significant margin, although squads will inevitably claw this back as they optimize their packages.

Air resistance has been reduced by 40%. The cars will utilize active aerodynamics – both wings will adjust on the straight sections to improve speed and increase straightline speed and revert into place for optimal grip in corners.

Tyres will keep the current rim size, but the tyres themselves will be reduced in width, by 25 millimetres on the front axle 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 ICE and the electrical system, up from about 20% battery contribution this year.

The energy recovery system is made less complex through the elimination of the MGU-H, the sophisticated and pricey device that harvested power from the exhaust turbo.

Every car on the grid will be obliged to compete on carbon-neutral fuel, produced using biomass or synthetic production methods.
