The world of Formula 1 has revealed the new terminology that will be used to describe the intricate details of its new 2026 regulations.

The sport is embarking on what is considered the largest rules overhaul in its long history starting in 2026, featuring revised car and engine specifications and the compulsory introduction of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which retain the hybrid V6 layout, boast a greatly enhanced electrical capacity, necessitating key advancements in the aero packages.

Over a race distance, competitors will tactically deploy ERS energy – potentially on qualifying laps – to achieve the optimal performance.

Extensive fan consultation were undertaken with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which terminology would improve understanding of the key features of the new regulations.

The stated goal was to make a set of intricate features of the racing as accessible as possible for the global fanbase.

Consequently, initial designations for certain devices – such as "modes labelled X and Z" for the active aerodynamics – have been phased out in favor of intuitive labels that directly explain the actual function of the innovation.

Key Technical Innovations

The FIA states that drivers will have greater control to determine tactics regarding battery management, regeneration, and efficiency.

The new regulations feature a set of functions that will be clearly indicated on television graphics to aid the audience's understanding of the race battle.

• Passing Mode: This takes over from the present overtaking aid. It provides a short boost of battery power accessible when a competitor is close behind the leading car to execute an overtaking maneuver.
• Extra Push Mode: This is a driver-operated battery discharge from the hybrid system that can be utilized during attack or defence. It delivers the pilot peak output at the click of a switch.

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

• Active Aero: Both the car's wings move automatically – spreading on the high-speed sections for reduced drag and increased velocity, and angling down in the turns for maximum downforce.
• Battery Recharge: Drivers can replenish their battery with power recovered from braking, or during coasting at the conclusion of a straight or in sections where only limited engine output is applied.

What's Changing on the Cars?

The next-generation machines will be more compact and lighter than this year, with a car length shortened by 200mm to 3,400mm, car width cut by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.

Cumulative downforce is projected to decrease by approximately 15-30%, although constructors will inevitably claw this back as they develop their cars.

Aerodynamic drag has been cut by 40%. The vehicles will utilize adjustable aero systems – front and rear wings will adjust on the straights to improve speed and boost top speed and revert into place for optimal grip in corners.

Pirelli tyres will continue to use the current rim size, but the actual tyres will be reduced in width, by 25mm at the front and 30 millimetres on the rear axle.

Power Unit Revolution

The revised hybrid units will have an roughly half-and-half distribution in horsepower generated by the internal combustion engine and the electrical system, up from about one-fifth electric power in the current formula.

The energy recovery system is simplified through the elimination of the MGU-H, the sophisticated and pricey device that harvested power from the turbocharger.

Every car on the grid will be mandated to operate on carbon-neutral fuel, produced using organic sources or synthetic industrial processes.
