The world of Formula 1 has introduced the official language that will be used to explain the advanced features of its revolutionary 2026 rulebook.

The championship is implementing what is potentially the largest technical shift in its competitive history next season, featuring new chassis and engine rules and the compulsory introduction of 100% sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which maintain the 1.6-litre V6 turbo hybrid, boast a significantly increased electrical capacity, driving key advancements in the aero packages.

Throughout races, competitors will strategically manage battery power – sometimes even hot laps – to achieve the optimal lap time.

Wide-ranging research were undertaken with a diverse audience, including new, casual and core fans, to determine which terminology would make things clearer of the main elements of the 2026 changes.

The stated goal was to render a set of intricate new areas of the competition as straightforward as possible for the broadest viewership.

Consequently, previous placeholder terms for certain devices – such as "x-mode and z-mode" for the moveable wings – have been phased out in preference for intuitive labels that succinctly convey the real-world effect of the innovation.

Exploring the New Tech

According to rule-makers that racers will have increased agency to determine tactics regarding energy deployment, harvesting, and saving energy.

The upcoming changes feature a range of settings that will be visually displayed on television graphics to improve the fans' insight of the on-track action.

• Attack Mode: This supersedes the present overtaking aid. It provides a surge of additional ERS power accessible when a car is less than a second the leading car to facilitate an pass.
• Boost Mode: This is a manual power boost from the energy recovery system that can be used in offensive or defensive moves. It provides the pilot maximum power at the click of a switch.

Both of these strategic tools will have to be managed carefully, as the available electrical charge is restricted.

• Active Aerodynamics: Both the car's wings move automatically – spreading on the straights for reduced drag and top speed, and sealing in the turns for maximum downforce.
• Recharge: The system can harvest energy with power recovered from braking, or during partial power application at the straight's end or in corners where only limited engine output is required.

Car Design Evolution

The 2026 cars will be reduced in size and weight than this year, with a car length reduced by 200mm to 3,400mm, car width cut by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Overall downforce is anticipated to be reduced by approximately a significant margin, although squads will undoubtedly recover some as they optimize their packages.

Drag has been reduced by 40%. The vehicles will utilize active aerodynamics – both wings will open on the straight sections to reduce drag and enhance velocity and return into place for peak handling.

Wheels will retain the current rim size, but the actual tyres will be reduced in width, by 25 millimetres on the front axle and 30 millimetres on the rear axle.

2026 Engine Regulations

The new power units will have an roughly half-and-half distribution in energy output by the internal combustion engine and the electrical system, increasing from about 20% battery contribution this year.

The energy recovery system is simplified through the deletion of the Motor Generator Unit – Heat, the sophisticated and pricey device that harvested power from the turbo.

Cars will be mandated to operate on carbon-neutral fuel, created from biomass or synthetic industrial processes.
