Formula 1 has introduced the simplified terminology that will be used to reference the technical complexities of its upcoming 2026 regulations.

The sport is introducing what is arguably the largest technical shift in its competitive history starting in 2026, featuring fresh chassis and power unit regulations and the required adoption of fully sustainable fuels.

The new power units, which keep the 1.6-litre V6 configuration, boast a significantly increased electrical capacity, requiring major innovations in the cars' aerodynamics.

During grand prix events, drivers will carefully oversee battery power – including during hot laps – to extract the peak lap time.

Extensive fan consultation were conducted with a mix of viewers, including new, casual and core fans, to identify which phrases would aid comprehension of the key features of the 2026 changes.

The primary aim was to present a series of complex new areas of the competition as easy to grasp as possible for the global fanbase.

Consequently, older technical labels for specific components – such as "x-mode and z-mode" for the adjustable aero – have been discarded in favor of descriptive names that clearly indicate the real-world effect of the technology.

Key Technical Innovations

Regulators explain that racers will have greater control to choose strategies regarding energy deployment, regeneration, and saving energy.

The upcoming changes feature a series of modes that will be visually displayed on television graphics to enhance the audience's understanding of the strategic duel.

• Attack Mode: This takes over from the present overtaking aid. It provides a surge of additional ERS power deployable when a driver is within one second the car ahead to execute an overtaking maneuver.
• Extra Push Mode: This is a manual power boost from the ERS that can be used in attack or defence. It grants the driver peak output at the push of a button.

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

• Adjustable Aero: Both the nose and rear wings move automatically – flattening on the high-speed sections for reduced drag and increased velocity, and sealing in the bends for peak grip.
• Recharge: Cars can harvest energy with regenerative braking, or during coasting at the end of straights or in certain corners where only partial power is applied.

Car Design Evolution

The next-generation machines will be smaller and lighter relative to current models, with a car length reduced by 200mm to 3,400mm, width cut by 100mm – down to 1,900mm – and the minimum weight decreased by 30kg.

Cumulative downforce is projected to decrease by approximately 15-30%, although teams will naturally regain performance as they optimize their packages.

Drag has been cut by 40%. The cars will feature moveable wing elements – both wings will open on the straight sections to cut resistance and increase straightline speed and return into place for peak handling.

Tyres will keep the current rim size, but the rubber compounds will be narrower, by 25mm at the front and 30mm at the rear.

Power Unit Revolution

The revised hybrid units will have an approximate 50-50 split in power produced by the ICE and the electrical system, up from about 20% electrical under present rules.

The ERS setup is made less complex through the removal of the Motor Generator Unit – Heat, the complicated and costly unit that harvested power from the turbocharger.

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