Formula 1 has revealed the simplified vocabulary that will be used to describe the intricate details of its upcoming 2026 rulebook.

The racing series is embarking on what is potentially the most significant rules overhaul in its illustrious history next season, featuring revised car and engine specifications and the compulsory introduction of fully sustainable fuels.

The new power units, which maintain the hybrid V6 layout, boast a significantly increased battery power, necessitating key advancements in the aero packages.

Throughout races, pilots will tactically deploy battery power – sometimes even qualifying laps – to achieve the optimal result.

Broad surveys were conducted with a mix of viewers, including long-time followers and newcomers, to determine which terms would improve understanding of the central aspects of the 2026 changes.

The primary aim was to render a range of advanced new areas of the competition as accessible as possible for the global fanbase.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the adjustable aero – have been phased out in favour of descriptive names that directly explain the real-world effect of the system.

Exploring the New Tech

According to rule-makers that racers will have greater control to make decisions regarding battery management, energy recovery, and efficiency.

The new regulations feature a range of settings that will be shown on TV overlays to enhance the audience's understanding of the race battle.

• Overtake Mode: This supersedes the existing Drag Reduction System. It provides a surge of additional ERS power available when a competitor is close behind the leading car to assist with an pass.
• Boost Mode: This is a driver-operated battery discharge from the energy recovery system that can be used in offensive or defensive moves. It grants the pilot full engine and battery energy at the push of a button.

Both of these crucial modes will have to be managed carefully, as the total energy is strictly limited.

• Active Aero: Both the car's wings adjust their angles – spreading on the long straight sections for minimal air resistance and higher speed, and angling down in the corners for maximum downforce.
• Battery Recharge: Cars can replenish their battery with power recovered from braking, or during coasting at the straight's end or in certain corners where only partial power is required.

Car Design Evolution

The vehicles for the new era will be more compact and lighter than this year, with a distance between axles reduced by 200mm to 3,400mm, overall width reduced by 100mm – down to 1,900mm – and the lowest permissible weight lowered by 30kg.

Cumulative downforce is projected to decrease by approximately fifteen to thirty percent, although constructors will undoubtedly recover some as they optimize their packages.

Drag has been cut by 40%. The vehicles will feature adjustable aero systems – front and rear wings will open on the straights to reduce drag and boost top speed and click back into place for peak handling.

Pirelli tyres will keep 18-inch wheel rims, but the actual tyres will be reduced in width, by 25mm at the front and three centimetres on the rear.

What's Changing in the Engines?

The revised hybrid units will have an near-equal balance in energy output by the ICE and the ERS, a rise from about one-fifth electric power this year.

The ERS setup is made less complex through the elimination of the complex turbo energy recovery device, the complicated and costly device that generated electricity from the turbo.

Every car on the grid will be obliged to compete on carbon-neutral fuel, produced using plant-based materials or lab-created processes.
