The world of Formula 1 has unveiled the official language that will be used to explain the technical complexities of its upcoming 2026 rulebook.

The sport is introducing what is arguably the most significant regulation change in its illustrious history starting in 2026, featuring revised car and engine specifications and the compulsory introduction of fully sustainable fuels.

The revised engines, which keep the 1.6-litre V6 turbo hybrid, boast a significantly increased energy storage, necessitating major innovations in the cars' aerodynamics.

Throughout races, pilots will carefully oversee ERS energy – potentially on hot laps – to achieve the optimal lap time.

Extensive fan consultation were conducted with a diverse audience, including new, casual and core fans, to understand which terminology would improve understanding of the central aspects of the upcoming rules.

The key objective was to make a series of complex new areas of the racing as easy to grasp as possible for the broadest viewership.

Consequently, older technical labels for specific components – such as "modes labelled X and Z" for the active aerodynamics – have been discarded in favor of straightforward terms that succinctly convey the primary purpose of the system.

What's the New Technology?

Regulators explain that competitors will have increased agency to choose strategies regarding power usage, regeneration, and conservation.

The 2026 rules feature a series of modes that will be clearly indicated on television graphics to improve the viewers' comprehension of the strategic duel.

• Passing Mode: This supersedes the present overtaking aid. It provides a short boost of battery power deployable when a driver is within one second the vehicle in front to execute an overtaking maneuver.
• Extra Push Mode: This is a on-demand power boost from the ERS that can be used in overtaking or defending. It grants the pilot full engine and battery energy at the click of a switch.

Both of these strategic tools will have to be deployed strategically, as the available electrical charge is capped.

• Active Aerodynamics: Both the front and rear wings move automatically – flattening on the straights for low aerodynamic resistance and increased velocity, and sealing in the bends for optimal cornering performance.
• Energy Harvesting: The system can replenish their battery with power recovered from braking, or during partial power application at the end of straights or in sections where only limited engine output is used.

2026 Car Specifications

The vehicles for the new era will be reduced in size and weight relative to current models, with a distance between axles cut by 200mm to 3,400mm, car width cut by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

Overall downforce is anticipated to be reduced by approximately 15-30%, although teams will undoubtedly recover some as they develop their cars.

Air resistance has been reduced by 40%. The vehicles will utilize adjustable aero systems – front and rear wings will move on the straight sections to improve speed and boost top speed and return into place for maximum cornering performance.

Wheels will continue to use 18-inch rims, but the actual tyres will be slimmer, by a quarter-centimetre on the front and 30mm at the rear.

2026 Engine Regulations

The 2026 engines will have an roughly half-and-half distribution in horsepower generated by the internal combustion engine and the battery and motor, increasing from about 20% electrical this year.

The energy recovery system is made less complex through the elimination of the complex turbo energy recovery device, the intricate and expensive component that recovered energy from the turbo.

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