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 embarking on what is arguably the largest regulation change in its illustrious history starting in 2026, featuring new chassis and engine rules and the required adoption of 100% sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which keep the 1.6-litre V6 configuration, boast a greatly enhanced battery power, requiring significant developments in the aero packages.

During grand prix events, drivers will strategically manage ERS energy – including during flying laps – to achieve the best lap time.

Broad surveys were conducted with a wide range of fans, including new, casual and core fans, to determine which phrases would aid comprehension of the main elements of the new regulations.

The stated goal was to render a series of complex new areas of the racing as easy to grasp as possible for the widest audience.

Consequently, older technical labels for specific components – such as "alphabetical mode names" for the adjustable aero – have been discarded in favor of intuitive labels that directly explain the primary purpose of the innovation.

Key Technical Innovations

According to rule-makers that competitors will have greater control to make decisions regarding battery management, harvesting, and saving energy.

The 2026 rules introduce a range of settings that will be visually displayed on television graphics to aid the viewers' comprehension of the race battle.

• Overtake Mode: This supersedes the current DRS. It provides a surge of additional ERS power deployable when a driver is close behind the leading car to facilitate an overtaking maneuver.
• Power Mode: This is a manual energy deployment from the ERS that can be used in attack or defence. It provides the driver full engine and battery energy at the click of a switch.

Both of these key functions will have to be managed carefully, as the overall battery capacity is capped.

• Active Aerodynamics: Both the car's wings move automatically – spreading on the straights for low aerodynamic resistance and increased velocity, and closing in the corners for optimal cornering performance.
• Recharge: Drivers can recharge the energy store with regenerative braking, or during coasting at the straight's end or in corners where only reduced throttle is required.

2026 Car Specifications

The 2026 cars will be more compact and lighter compared to the 2025 spec, with a car length reduced by 200mm to 3,400mm, overall width cut by 100mm – down to 1,900mm – and the car weight lowered by 30kg.

Total aerodynamic grip is expected to drop by approximately a significant margin, although teams will naturally regain performance as they develop their cars.

Drag has been cut by 40%. The vehicles will utilize active aerodynamics – front and rear wings will open on the straight sections to cut resistance and enhance velocity and return into place for optimal grip in corners.

Pirelli tyres will keep 18-inch wheel rims, but the rubber compounds will be narrower, by 25 millimetres on the front axle and 30mm at the rear.

What's Changing in the Engines?

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, increasing from about one-fifth electric power this year.

The hybrid system is made less complex through the removal of the complex turbo energy recovery device, the intricate and expensive device that generated electricity from the turbocharger.

Cars will be obliged to compete on 100% sustainable fuel, created from organic sources or lab-created processes.
