Formula 1 has unveiled the simplified vocabulary that will be used to describe the intricate details of its upcoming 2026 rulebook.

The championship is implementing what is arguably the most significant rules overhaul in its illustrious history next season, featuring revised car and engine specifications and the required adoption of 100% sustainable fuels.

The revised engines, which retain the hybrid V6 layout, boast a significantly increased energy storage, requiring major innovations in the aero packages.

Throughout races, competitors will carefully oversee electrical energy – potentially on hot laps – to extract the best result.

Broad surveys were carried out with a wide range of fans, including long-time followers and newcomers, to determine which terminology would make things clearer of the central aspects of the upcoming rules.

The primary aim was to present a set of intricate new areas of the competition as accessible as possible for the global fanbase.

Consequently, previous placeholder terms for some systems – such as "alphabetical mode names" for the adjustable aero – have been phased out in favour of descriptive names that succinctly convey the real-world effect of the technology.

Exploring the New Tech

According to rule-makers that competitors will have more power to determine tactics regarding power usage, energy recovery, and conservation.

The 2026 rules introduce a series of modes that will be shown on television graphics to enhance the fans' insight of the strategic duel.

• Attack Mode: This replaces the existing Drag Reduction System. It provides a surge of additional ERS power accessible when a competitor is close behind the leading car to execute an overtake.
• Extra Push Mode: This is a driver-operated battery discharge from the hybrid system that can be used in overtaking or defending. It grants the driver full engine and battery energy at the click of a switch.

Both of these key functions will have to be used with calculation, as the overall battery capacity is capped.

• Active Aero: Both the nose and rear wings change configuration – spreading on the high-speed sections for reduced drag and higher speed, and sealing in the bends for optimal cornering performance.
• Recharge: Drivers can replenish their battery with regenerative braking, or during throttle lift at the conclusion of a straight or in sections where only reduced throttle is used.

2026 Car Specifications

The vehicles for the new era will be reduced in size and weight compared to the 2025 spec, with a distance between axles shortened by 200mm to 3,400mm, car width reduced by 100mm – down to 1,900mm – and the car weight reduced by 30kg.

Cumulative downforce is expected to drop by approximately fifteen to thirty percent, although squads will undoubtedly recover some as they develop their cars.

Air resistance has been reduced by 40%. The vehicles will feature moveable wing elements – front and rear wings will open on the straights to cut resistance and enhance velocity and return into place for optimal grip in corners.

Wheels will continue to use 18-inch wheel rims, but the tyres themselves will be reduced in width, by a quarter-centimetre on the front and 30mm at the rear.

Power Unit Revolution

The new power units will have an roughly half-and-half distribution in energy output by the internal combustion engine and the ERS, a rise from about 20% electrical this year.

The energy recovery system is simplified through the removal of the complex turbo energy recovery device, the complicated and costly unit that harvested power from the turbo.

Cars will be obliged to compete on carbon-neutral fuel, created from biomass or synthetic industrial processes.
