The world of Formula 1 has unveiled the new language that will be used to explain the intricate details of its revolutionary 2026 technical rules.

The sport is implementing what is arguably the biggest rules overhaul in its illustrious history for the 2026 campaign, featuring revised car and engine specifications and the required adoption of fully sustainable fuels.

The revised engines, which retain the 1.6-litre V6 turbo hybrid, boast a greatly enhanced energy storage, necessitating major innovations in the aero packages.

Over a race distance, pilots will strategically manage battery power – including during hot laps – to achieve the optimal lap time.

Wide-ranging research were undertaken with a diverse audience, including new, casual and core fans, to understand which terms would improve understanding of the central aspects of the new regulations.

The primary aim was to present a set of intricate features of the racing as accessible as possible for the widest audience.

Consequently, older technical labels for some systems – such as "alphabetical mode names" for the active aerodynamics – have been phased out in favor of descriptive names that clearly indicate the actual function of the innovation.

Key Technical Innovations

The FIA states that racers will have more power to determine tactics regarding energy deployment, energy recovery, and conservation.

The new regulations introduce a set of functions that will be visually displayed on broadcast screens to improve the audience's understanding of the strategic duel.

• Overtake Mode: This replaces the current DRS. It provides a surge of additional ERS power accessible when a car is less than a second the vehicle in front to assist with an overtake.
• Extra Push Mode: This is a driver-operated power boost from the energy recovery system that can be deployed for overtaking or defending. It grants the pilot peak output at the click of a switch.

Both of these strategic tools will have to be managed carefully, as the available electrical charge is strictly limited.

• Adjustable Aero: Both the nose and rear wings change configuration – opening on the long straight sections for minimal air resistance and increased velocity, and sealing in the turns for peak grip.
• Battery Recharge: The system can recharge the energy store with power recovered from braking, or during partial power application at the conclusion of a straight or in certain corners 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, overall width narrowed by 100mm – down to 1,900mm – and the minimum weight reduced by 30kg.

Cumulative downforce is anticipated to be reduced by approximately 15-30%, although teams will undoubtedly recover some as they refine their designs.

Aerodynamic drag has been reduced by 40%. The vehicles will employ active aerodynamics – both wings will move on the straights to reduce drag and increase straightline speed and return into place for peak handling.

Tyres will retain 18-inch wheel rims, but the tyres themselves will be reduced in width, by 25 millimetres on the front axle and three centimetres on the rear.

2026 Engine Regulations

The 2026 engines will have an roughly half-and-half distribution in power produced by the internal combustion engine and the electrical system, up from about one-fifth electric power under present rules.

The hybrid system is simplified through the removal of the complex turbo energy recovery device, the intricate and expensive unit that harvested power from the turbocharger.

Cars will be required to run on fully sustainable fuel, produced using plant-based materials or synthetic production methods.
