F1 has introduced the official language that will be used to reference the advanced features of its upcoming 2026 rulebook.

The racing series is implementing what is potentially the most significant regulation change in its long history next season, featuring revised car and engine specifications and the compulsory introduction of 100% sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which maintain the hybrid V6 layout, boast a significantly increased electrical capacity, necessitating significant developments in the cars' aerodynamics.

Throughout races, drivers will strategically manage ERS energy – including during qualifying laps – to achieve the optimal performance.

Broad surveys were conducted with a diverse audience, including new, casual and core fans, to identify which terminology would make things clearer of the key features of the new regulations.

The primary aim was to make a range of advanced features of the sport as straightforward as possible for the widest audience.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the adjustable aero – have been phased out in favor of intuitive labels that directly explain the actual function of the innovation.

Exploring the New Tech

The FIA states that racers will have more power to make decisions regarding energy deployment, regeneration, and conservation.

The upcoming changes feature a set of functions that will be visually displayed on television graphics to aid the audience's understanding of the on-track action.

• Attack Mode: This supersedes the present overtaking aid. It provides a short boost of battery power available when a driver is within one second the leading car to assist with an overtake.
• Boost Mode: This is a on-demand power boost from the hybrid system that can be utilized during attack or defence. It delivers the pilot maximum power at the activation of a control.

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

• Active Aerodynamics: Both the front and rear wings adjust their angles – spreading on the straights for minimal air resistance and higher speed, and closing in the corners for maximum downforce.
• Battery Recharge: Drivers can replenish their battery with regenerative braking, or during coasting at the straight's end or in corners where only partial power is required.

2026 Car Specifications

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

Cumulative downforce is anticipated to be reduced by approximately 15-30%, although squads will undoubtedly recover some as they optimize their packages.

Air resistance has been reduced by 40%. The cars will employ active aerodynamics – front and rear wings will adjust on the straight sections to improve speed and boost top speed and click back into place for peak handling.

Tyres will keep the current rim size, but the actual tyres will be slimmer, by 25mm at the front and 30mm at the rear.

What's Changing in the Engines?

The revised hybrid units will have an roughly half-and-half distribution in horsepower generated by the internal combustion engine and the ERS, a rise from about one-fifth electric power this year.

The ERS setup is simplified through the removal of the complex turbo energy recovery device, the complicated and costly component that recovered energy from the exhaust turbo.

All vehicles will be mandated to operate on 100% sustainable fuel, created from organic sources or lab-created processes.
