F1 has introduced the simplified vocabulary that will be used to reference the advanced features of its upcoming 2026 technical rules.

The sport is embarking on what is arguably the largest rules overhaul in its long history starting in 2026, featuring fresh chassis and power unit regulations and the mandatory use of eco-friendly fuels.

The new power units, which retain the 1.6-litre V6 turbo hybrid, boast a significantly increased electrical capacity, driving key advancements in the aero packages.

Over a race distance, drivers will carefully oversee electrical energy – sometimes even qualifying laps – to extract the best result.

Wide-ranging research were carried out with a diverse audience, including new, casual and core fans, to determine which terminology would aid comprehension of the main elements of the new regulations.

The stated goal was to render a series of complex features of the sport as easy to grasp as possible for the global fanbase.

Consequently, previous placeholder terms for certain devices – such as "x-mode and z-mode" for the active aerodynamics – have been phased out in favor of intuitive labels that succinctly convey the real-world effect of the system.

Key Technical Innovations

According to rule-makers that competitors will have increased agency to choose strategies regarding energy deployment, regeneration, and efficiency.

The upcoming changes feature a series of modes that will be clearly indicated on television graphics to aid the fans' insight of the race battle.

• Overtake Mode: This supersedes the current DRS. It provides a short boost of battery power accessible when a car is close behind the vehicle in front to assist with an pass.
• Boost Mode: This is a manual battery discharge from the energy recovery system that can be utilized during overtaking or defending. It grants the driver full engine and battery energy at the click of a switch.

Both of these strategic tools will have to be used with calculation, as the total energy is restricted.

• Active Aerodynamics: Both the front and rear wings adjust their angles – opening on the straights for reduced drag and top speed, and sealing in the bends for peak grip.
• Energy Harvesting: Drivers can harvest energy with energy harvested under braking, or during coasting at the conclusion of a straight or in certain corners where only limited engine output is required.

2026 Car Specifications

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

Total aerodynamic grip is anticipated to be reduced by approximately 15-30%, although constructors will naturally regain performance as they develop their cars.

Air resistance has been reduced by 40%. The vehicles will feature adjustable aero systems – both wings will adjust on the straights to improve speed and enhance velocity and revert into place for optimal grip in corners.

Tyres will continue to use 18-inch wheel rims, but the tyres themselves will be narrower, by 25mm at the front and three centimetres on the rear.

Power Unit Revolution

The 2026 engines will have an approximate 50-50 split in horsepower generated by the internal combustion engine and the battery and motor, increasing from about one-fifth electric power in the current formula.

The hybrid system is streamlined through the deletion of the Motor Generator Unit – Heat, the intricate and expensive device that harvested power from the turbocharger.

Cars will be mandated to operate on carbon-neutral fuel, created from plant-based materials or synthetic industrial processes.
