The world of Formula 1 has introduced the new language that will be used to describe the advanced features of its upcoming 2026 regulations.

The championship is embarking on what is arguably the largest technical shift in its long history starting in 2026, featuring new chassis and engine rules and the required adoption of fully sustainable fuels.

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

During grand prix events, competitors will tactically deploy electrical energy – potentially on hot laps – to secure the peak result.

Extensive fan consultation were carried out with a mix of viewers, including long-time followers and newcomers, to determine which terms would make things clearer of the central aspects of the new regulations.

The primary aim was to present a set of intricate new areas of the racing as easy to grasp as possible for the global fanbase.

Consequently, older technical labels for some systems – such as "modes labelled X and Z" for the active aerodynamics – have been discarded in favour of intuitive labels that clearly indicate the real-world effect of the system.

What's the New Technology?

The FIA states that competitors will have greater control to make decisions regarding power usage, harvesting, and saving energy.

The upcoming changes mandate a range of settings that will be clearly indicated on television graphics to improve the fans' insight of the strategic duel.

• Attack Mode: This replaces the present overtaking aid. It provides a surge of additional ERS power accessible when a driver is close behind the leading car to execute an overtaking maneuver.
• Extra Push Mode: This is a on-demand energy deployment from the energy recovery system that can be utilized during offensive or defensive moves. It provides the pilot maximum power at the activation of a control.

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

• Active Aero: Both the nose and rear wings move automatically – spreading on the straights for reduced drag and increased velocity, and closing in the corners for maximum downforce.
• Energy Harvesting: The system can recharge the energy store with power recovered from braking, or during coasting at the straight's end or in certain corners where only partial power is applied.

2026 Car Specifications

The 2026 cars will be smaller and lighter compared to the 2025 spec, with a distance between axles reduced by 200mm to 3,400mm, overall width cut by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

Cumulative downforce is expected to drop by approximately 15-30%, although squads will inevitably claw this back as they develop their cars.

Air resistance has been reduced by 40%. The cars will feature adjustable aero systems – both wings will open on the straights to reduce drag and boost top speed and revert into place for peak handling.

Pirelli tyres will retain the current rim size, but the rubber compounds will be reduced in width, by 25 millimetres on the front axle and 30mm at the rear.

2026 Engine Regulations

The revised hybrid units will have an near-equal balance in energy output by the internal combustion engine and the battery and motor, up from about 20% battery contribution under present rules.

The hybrid system is made less complex through the elimination of the MGU-H, the intricate and expensive device that generated electricity from the exhaust turbo.

Every car on the grid will be mandated to operate on 100% sustainable fuel, created from organic sources or synthetic industrial processes.
