Formula 1 has unveiled the simplified vocabulary that will be used to describe the technical complexities of its new 2026 regulations.

The championship is implementing what is considered the largest rules overhaul in its long history for the 2026 campaign, featuring fresh chassis and power unit regulations and the required adoption of fully sustainable fuels.

The new power units, which maintain the 1.6-litre V6 configuration, boast a greatly enhanced battery power, necessitating key advancements in the aero packages.

Over a race distance, pilots will tactically deploy battery power – sometimes even qualifying laps – to secure the optimal performance.

Broad surveys were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which terms would aid comprehension of the key features of the upcoming rules.

The primary aim was to make a range of advanced features of the sport as easy to grasp as possible for the broadest viewership.

Consequently, older technical labels for certain devices – such as "alphabetical mode names" for the adjustable aero – have been discarded in preference for intuitive labels that clearly indicate the primary purpose of the system.

Exploring the New Tech

The FIA states that racers will have greater control to determine tactics regarding power usage, regeneration, and saving energy.

The 2026 rules mandate a set of functions that will be clearly indicated on broadcast screens to enhance the audience's understanding of the strategic duel.

• Overtake Mode: This replaces the current DRS. It provides a burst of extra electrical energy deployable when a car is within one second the leading car to execute an overtaking maneuver.
• Power Mode: This is a on-demand energy deployment from the ERS that can be used in offensive or defensive moves. It provides the pilot maximum power at the activation of a control.

Both of these key functions will have to be managed carefully, as the available electrical charge is capped.

• Adjustable Aero: Both the front and rear wings move automatically – spreading on the straights for low aerodynamic resistance and increased velocity, and closing in the bends for peak grip.
• Battery Recharge: The system can harvest energy with power recovered from braking, or during coasting at the conclusion of a straight or in corners where only partial power is used.

Car Design Evolution

The next-generation machines will be smaller and lighter than this year, with a wheelbase reduced by 200mm to 3,400mm, width reduced by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Total aerodynamic grip is anticipated to be reduced by approximately a significant margin, although squads will undoubtedly recover some as they refine their designs.

Drag has been slashed by 40%. The vehicles will utilize adjustable aero systems – front and rear wings will move on the straight sections to reduce drag and increase straightline speed and return into place for optimal grip in corners.

Tyres will keep 18-inch rims, but the rubber compounds will be narrower, by 25mm at the front and 30 millimetres on the rear axle.

What's Changing in the Engines?

The revised hybrid units will have an near-equal balance in power produced by the internal combustion engine and the battery and motor, increasing from about one-fifth electric power this year.

The ERS setup is made less complex through the elimination of the MGU-H, the intricate and expensive device that recovered energy from the turbo.

All vehicles will be obliged to compete on fully sustainable fuel, manufactured from organic sources or synthetic production methods.
