Formula 1 has unveiled the official terminology that will be used to describe the technical complexities of its revolutionary 2026 technical rules.

The racing series is embarking on what is arguably the biggest technical shift in its illustrious history for the 2026 campaign, featuring new chassis and engine rules and the mandatory use of 100% sustainable fuels.

The new power units, which maintain the 1.6-litre V6 turbo hybrid, boast a significantly increased energy storage, necessitating key advancements in the cars' aerodynamics.

Throughout races, competitors will carefully oversee electrical energy – sometimes even qualifying laps – to extract the peak result.

Extensive fan consultation were conducted with a diverse audience, including long-time followers and newcomers, to identify which phrases would improve understanding of the central aspects of the 2026 changes.

The stated goal was to render a range of advanced technical aspects of the competition as accessible as possible for the widest audience.

Consequently, previous placeholder terms for specific components – such as "x-mode and z-mode" for the adjustable aero – have been abandoned in preference for descriptive names that directly explain the actual function of the technology.

Key Technical Innovations

Regulators explain that drivers will have greater control to choose strategies regarding power usage, harvesting, and efficiency.

The upcoming changes mandate a range of settings that will be clearly indicated on television graphics to aid the viewers' comprehension of the strategic duel.

• Overtake Mode: This takes over from the present overtaking aid. It provides a burst of extra electrical energy available when a car is within one second the vehicle in front to execute an overtaking maneuver.
• Power Mode: This is a driver-operated battery discharge from the energy recovery system that can be utilized during offensive or defensive moves. It delivers the pilot peak output at the push of a button.

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

• Active Aero: Both the car's wings move automatically – spreading on the long straight sections for minimal air resistance and higher speed, and closing in the turns for optimal cornering performance.
• Energy Harvesting: Cars can replenish their battery with energy harvested under braking, or during partial power application at the conclusion of a straight or in certain corners where only limited engine output is applied.

Car Design Evolution

The next-generation machines 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 reduced by 30kg.

Total aerodynamic grip is anticipated to be reduced by approximately fifteen to thirty percent, although teams will naturally regain performance as they develop their cars.

Aerodynamic drag has been reduced by 40%. The cars will employ adjustable aero systems – both wings will adjust on the straight sections to cut resistance and boost top speed and revert into place for peak handling.

Wheels will retain the current rim size, but the actual tyres will be slimmer, by 25mm at the front and three centimetres on the rear.

What's Changing in the Engines?

The 2026 engines will have an approximate 50-50 split in energy output by the internal combustion engine and the battery and motor, up from about one-fifth electric power in the current formula.

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

Every car on the grid will be obliged to compete on fully sustainable fuel, produced using biomass or synthetic industrial processes.
