F1 has introduced the simplified vocabulary that will be used to explain the intricate details of its revolutionary 2026 rulebook.

The racing series is implementing what is considered the most significant rules overhaul in its competitive history starting in 2026, featuring fresh chassis and power unit regulations and the mandatory use of 100% sustainable fuels.

The new power units, which keep the 1.6-litre V6 configuration, boast a substantially higher battery power, driving major innovations in the cars' aerodynamics.

Over a race distance, drivers will tactically deploy battery power – including during flying laps – to achieve the best lap time.

Broad surveys were conducted with a diverse audience, including new, casual and core fans, to understand which phrases would improve understanding of the central aspects of the new regulations.

The key objective was to make a set of intricate new areas of the competition as easy to grasp as possible for the broadest viewership.

Consequently, previous placeholder terms for certain devices – such as "alphabetical mode names" for the active aerodynamics – have been discarded in preference for straightforward terms that directly explain the primary purpose of the system.

Exploring the New Tech

The FIA states that racers will have more power to choose strategies regarding energy deployment, energy recovery, and efficiency.

The upcoming changes feature a set of functions that will be clearly indicated on TV overlays to improve the audience's understanding of the race battle.

• Passing Mode: This replaces the present overtaking aid. It provides a burst of extra electrical energy accessible when a car is less than a second the vehicle in front to assist with an overtake.
• Power Mode: This is a on-demand energy deployment from the energy recovery system that can be utilized during overtaking or defending. It provides the driver peak output at the click of a switch.

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

• Active Aerodynamics: Both the car's wings adjust their angles – opening on the long straight sections for minimal air resistance and increased velocity, and sealing in the turns for peak grip.
• Recharge: Drivers can harvest energy with regenerative braking, or during partial power application at the straight's end or in sections where only reduced throttle is used.

Car Design Evolution

The next-generation machines will be reduced in size and weight than this year, with a wheelbase shortened by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.

Cumulative downforce is expected to drop by approximately fifteen to thirty percent, although teams will naturally regain performance as they refine their designs.

Drag has been reduced by 40%. The cars will employ active aerodynamics – both wings will move on the straights to reduce drag and enhance velocity and revert into place for peak handling.

Pirelli tyres will keep 18-inch rims, but the actual tyres will be narrower, by a quarter-centimetre on the front and three centimetres on the rear.

2026 Engine Regulations

The 2026 engines will have an near-equal balance in power produced by the petrol engine and the ERS, up from about 20% electrical in the current formula.

The ERS setup is made less complex through the removal of the Motor Generator Unit – Heat, the intricate and expensive device that generated electricity from the exhaust turbo.

Cars will be mandated to operate on carbon-neutral fuel, produced using plant-based materials or lab-created processes.
