The world of Formula 1 has introduced the official terminology that will be used to reference the advanced features of its revolutionary 2026 technical rules.

The racing series is implementing what is considered the biggest regulation change in its illustrious history next season, featuring fresh chassis and power unit regulations and the mandatory use of fully sustainable fuels.

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

Over a race distance, competitors will strategically manage ERS energy – sometimes even flying laps – to achieve the optimal performance.

Broad surveys were undertaken with a mix of viewers, including new, casual and core fans, to determine which terminology would aid comprehension of the central aspects of the 2026 changes.

The primary aim was to make a series of complex features of the sport as straightforward as possible for the widest audience.

Consequently, initial designations for certain devices – such as "alphabetical mode names" for the moveable wings – have been phased out in preference for descriptive names that succinctly convey the actual function of the technology.

Key Technical Innovations

According to rule-makers that racers will have more power to make decisions regarding battery management, regeneration, and efficiency.

The new regulations introduce a series of modes that will be shown on television graphics to improve the fans' insight of the race battle.

• Passing Mode: This takes over from the present overtaking aid. It provides a surge of additional ERS power accessible when a competitor is less than a second the leading car to execute an pass.
• Power Mode: This is a driver-operated power boost from the hybrid system that can be used in offensive or defensive moves. It provides the pilot peak output at the click of a switch.

Both of these strategic tools will have to be used with calculation, as the available electrical charge is capped.

• Active Aerodynamics: Both the front and rear wings move automatically – opening on the long straight sections for reduced drag and top speed, and angling down in the bends for optimal cornering performance.
• Recharge: Cars can recharge the energy store with power recovered from braking, or during throttle lift at the conclusion of a straight or in corners where only reduced throttle is applied.

2026 Car Specifications

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

Total aerodynamic grip is expected to drop by approximately 15-30%, although constructors will naturally regain performance as they refine their designs.

Air resistance has been cut by 40%. The cars will feature active aerodynamics – both wings will move on the straights to reduce drag and enhance velocity and return into place for peak handling.

Wheels will retain 18-inch wheel rims, but the tyres themselves will be reduced in width, by 25 millimetres on the front axle and 30 millimetres on the rear axle.

2026 Engine Regulations

The revised hybrid units will have an near-equal balance in energy output by the petrol engine and the ERS, a rise from about 20% battery contribution under present rules.

The ERS setup is made less complex through the removal of the complex turbo energy recovery device, the sophisticated and pricey device that generated electricity from the turbocharger.

All vehicles will be required to run on 100% sustainable fuel, manufactured from biomass or synthetic production methods.
