The world of Formula 1 has introduced the official vocabulary that will be used to describe the technical complexities of its new 2026 rulebook.

The championship is embarking on what is considered the biggest technical shift in its long history starting in 2026, featuring fresh chassis and power unit regulations and the compulsory introduction of 100% sustainable fuels.

The revised engines, which retain the 1.6-litre V6 turbo hybrid, boast a substantially higher battery power, necessitating key advancements in the cars' aerodynamics.

During grand prix events, competitors will carefully oversee ERS energy – potentially on flying laps – to extract the optimal lap time.

Wide-ranging research were carried out with a diverse audience, including dedicated enthusiasts and casual observers, to understand which terms would improve understanding of the main elements of the new regulations.

The key objective was to render a set of intricate features of the racing as accessible as possible for the broadest viewership.

Consequently, initial designations for certain devices – such as "alphabetical mode names" for the active aerodynamics – have been phased out in preference for intuitive labels that directly explain the real-world effect of the system.

Exploring the New Tech

Regulators explain that competitors will have increased agency to make decisions regarding power usage, energy recovery, and conservation.

The 2026 rules introduce a series of modes that will be clearly indicated on TV overlays to enhance the audience's understanding of the strategic duel.

• Attack Mode: This takes over from the existing Drag Reduction System. It provides a short boost of battery power accessible when a driver is less than a second the vehicle in front to execute an overtake.
• Extra Push Mode: This is a on-demand energy deployment from the energy recovery system that can be deployed for overtaking or defending. It grants the driver peak output at the push of a button.

Both of these key functions will have to be used with calculation, as the total energy is capped.

• Adjustable Aero: Both the nose and rear wings move automatically – flattening on the long straight sections for low aerodynamic resistance and top speed, and sealing in the corners for peak grip.
• Energy Harvesting: Drivers can harvest energy with power recovered from braking, or during coasting at the straight's end or in sections where only partial power is required.

Car Design Evolution

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

Total aerodynamic grip is anticipated to be reduced by approximately fifteen to thirty percent, although squads will naturally regain performance as they refine their designs.

Air resistance has been slashed by 40%. The cars will utilize active aerodynamics – front and rear wings will open on the straight sections to improve speed and increase straightline speed and click back into place for optimal grip in corners.

Wheels will retain 18-inch wheel rims, but the actual tyres will be narrower, by a quarter-centimetre on the front and three centimetres on 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 petrol engine and the ERS, up from about one-fifth electric power under present rules.

The energy recovery system is simplified through the deletion of the MGU-H, the intricate and expensive unit that generated electricity from the turbo.

All vehicles will be mandated to operate on 100% sustainable fuel, manufactured from biomass or synthetic production methods.
