Formula 1 has revealed the simplified language that will be used to describe the intricate details of its revolutionary 2026 technical rules.

The sport is implementing what is potentially the most significant rules overhaul in its long history next season, featuring fresh chassis and power unit regulations and the required adoption of 100% sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which maintain the hybrid V6 layout, boast a substantially higher electrical capacity, requiring major innovations in the aero packages.

During grand prix events, pilots will tactically deploy ERS energy – including during flying laps – to extract the best performance.

Wide-ranging research were undertaken with a wide range of fans, including long-time followers and newcomers, to identify which terms would make things clearer of the key features of the upcoming rules.

The key objective was to present a set of intricate features of the sport as straightforward as possible for the widest audience.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the adjustable aero – have been discarded in favor of straightforward terms that clearly indicate the real-world effect of the system.

Exploring the New Tech

Regulators explain that racers will have more power to choose strategies regarding power usage, harvesting, and conservation.

The upcoming changes introduce a set of functions that will be shown on broadcast screens to improve the fans' insight of the race battle.

• Overtake Mode: This takes over from the present overtaking aid. It provides a short boost of battery power available when a competitor is within one second the leading car to execute an overtaking maneuver.
• Boost Mode: This is a on-demand power boost from the ERS that can be utilized during overtaking or defending. It grants the pilot peak output at the activation of a control.

Both of these key functions will have to be deployed strategically, as the available electrical charge is strictly limited.

• Adjustable Aero: Both the car's wings adjust their angles – spreading on the high-speed sections for low aerodynamic resistance and higher speed, and angling down in the bends for maximum downforce.
• Recharge: Cars can harvest energy with regenerative braking, or during throttle lift at the straight's end or in corners where only reduced throttle is required.

2026 Car Specifications

The next-generation machines will be reduced in size and weight compared to the 2025 spec, with a distance between axles reduced by 200mm to 3,400mm, width cut by 100mm – down to 1,900mm – and the lowest permissible weight reduced by 30kg.

Cumulative downforce is anticipated to be reduced by approximately a significant margin, although constructors will undoubtedly recover some as they refine their designs.

Drag has been cut by 40%. The cars will employ active aerodynamics – front and rear wings will open on the straight sections to reduce drag and enhance velocity and return into place for maximum cornering performance.

Tyres will keep the current rim size, but the actual tyres will be slimmer, by 25 millimetres on the front axle and three centimetres on 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 battery and motor, a rise from about 20% battery contribution in the current formula.

The hybrid system is simplified through the elimination of the MGU-H, the intricate and expensive device that generated electricity from the turbo.

Every car on the grid will be obliged to compete on 100% sustainable fuel, produced using organic sources or lab-created processes.
