The world of Formula 1 has introduced the new vocabulary that will be used to explain the intricate details of its revolutionary 2026 regulations.

The sport is introducing what is potentially the most significant technical shift in its illustrious history next season, featuring new chassis and engine rules and the mandatory use of 100% sustainable fuels.

The revised engines, which maintain the 1.6-litre V6 configuration, boast a greatly enhanced energy storage, requiring major innovations in the aero packages.

During grand prix events, drivers will tactically deploy battery power – potentially on hot laps – to achieve the best performance.

Broad surveys were carried out with a diverse audience, including new, casual and core fans, to identify which terms would make things clearer of the central aspects of the 2026 changes.

The primary aim was to make a range of advanced new areas of the competition as accessible as possible for the broadest viewership.

Consequently, older technical labels for specific components – such as "x-mode and z-mode" for the moveable wings – have been abandoned in favour of descriptive names that directly explain the real-world effect of the innovation.

What's the New Technology?

According to rule-makers that racers will have increased agency to choose strategies regarding power usage, regeneration, and conservation.

The new regulations introduce a set of functions that will be visually displayed on broadcast screens to aid the fans' insight of the race battle.

• 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 leading car to assist with an pass.
• Power Mode: This is a on-demand power boost from the ERS that can be deployed for overtaking or defending. It provides the driver maximum power at the activation of a control.

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

• Active Aero: Both the nose and rear wings change configuration – opening on the long straight sections for minimal air resistance and top speed, and sealing in the turns for maximum downforce.
• Battery Recharge: The system can replenish their battery with power recovered from braking, or during coasting at the straight's end or in sections where only partial power is used.

What's Changing on the Cars?

The next-generation machines will be more compact and lighter compared to the 2025 spec, with a car length cut by 200mm to 3,400mm, overall width narrowed by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

Total aerodynamic grip is anticipated to be reduced by approximately a significant margin, although squads will naturally regain performance as they refine their designs.

Drag has been reduced by 40%. The cars will utilize active aerodynamics – both wings will adjust on the straights to cut resistance and increase straightline speed and revert into place for optimal grip in corners.

Wheels will retain the current rim size, but the tyres themselves will be slimmer, by 25mm at the front and 30 millimetres on the rear axle.

2026 Engine Regulations

The revised hybrid units will have an roughly half-and-half distribution in energy output by the petrol engine and the battery and motor, increasing from about 20% battery contribution under present rules.

The energy recovery system is simplified through the elimination of the complex turbo energy recovery device, the sophisticated and pricey component that harvested power from the exhaust turbo.

Cars will be obliged to compete on fully sustainable fuel, produced using biomass or synthetic industrial processes.
