The world of Formula 1 has introduced the simplified terminology that will be used to explain the intricate details of its new 2026 technical rules.

The championship is introducing what is arguably the largest technical shift in its illustrious history next season, featuring new chassis and engine rules and the compulsory introduction of eco-friendly fuels.

The updated 1.6-litre V6 turbo hybrids, which retain the hybrid V6 layout, boast a significantly increased electrical capacity, necessitating significant developments in the vehicles' aerodynamic design.

During grand prix events, competitors will tactically deploy ERS energy – potentially on qualifying laps – to secure the peak performance.

Broad surveys were carried out with a diverse audience, including new, casual and core fans, to determine which terms would improve understanding of the central aspects of the upcoming rules.

The primary aim was to render a series of complex features of the sport as accessible as possible for the broadest viewership.

Consequently, initial designations for specific components – such as "x-mode and z-mode" for the moveable wings – have been discarded in favour of intuitive labels that succinctly convey the actual function of the innovation.

Exploring the New Tech

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

The new regulations feature a set of functions that will be visually displayed on TV overlays to enhance the viewers' comprehension of the race battle.

• Attack Mode: This takes over from the existing Drag Reduction System. It provides a burst of extra electrical energy available when a car is within one second the leading car to facilitate an overtaking maneuver.
• Boost Mode: This is a on-demand energy deployment from the ERS that can be used in offensive or defensive moves. It provides the pilot maximum power at the push of a button.

Both of these strategic tools will have to be deployed strategically, as the total energy is capped.

• Active Aerodynamics: Both the car's wings change configuration – flattening on the long straight sections for reduced drag and higher speed, and sealing in the corners for maximum downforce.
• Battery Recharge: Drivers can replenish their battery with energy harvested under braking, or during partial power application at the end of straights or in certain corners where only limited engine output is required.

What's Changing on the Cars?

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

Total aerodynamic grip is anticipated to be reduced by approximately a significant margin, although constructors will undoubtedly recover some as they refine their designs.

Air resistance has been slashed by 40%. The vehicles will employ active aerodynamics – both wings will move on the straight sections to improve speed and enhance velocity and click back into place for peak handling.

Pirelli tyres will keep 18-inch rims, but the tyres themselves will be narrower, by 25 millimetres on the front axle and 30 millimetres on the rear axle.

2026 Engine Regulations

The revised hybrid units will have an roughly half-and-half distribution in horsepower generated by the internal combustion engine and the electrical system, a rise from about one-fifth electric power under present rules.

The energy recovery system is made less complex through the elimination of the Motor Generator Unit – Heat, the sophisticated and pricey device that harvested power from the exhaust turbo.

Cars will be required to run on 100% sustainable fuel, created from organic sources or lab-created processes.
