The world of Formula 1 has revealed the simplified language that will be used to explain the technical complexities of its upcoming 2026 rulebook.

The sport is implementing what is potentially the largest technical shift in its competitive history for the 2026 campaign, featuring fresh chassis and power unit regulations and the required adoption of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which maintain the 1.6-litre V6 configuration, boast a greatly enhanced battery power, driving major innovations in the vehicles' aerodynamic design.

Over a race distance, drivers will carefully oversee battery power – potentially on flying laps – to achieve the peak lap time.

Wide-ranging research were undertaken with a diverse audience, including long-time followers and newcomers, to understand which terms would improve understanding of the key features of the 2026 changes.

The stated goal was to render a range of advanced features of the sport as accessible as possible for the broadest viewership.

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

Exploring the New Tech

Regulators explain that racers will have more power to make decisions regarding battery management, regeneration, and saving energy.

The new regulations introduce a set of functions that will be shown on TV overlays to aid the audience's understanding of the race battle.

• Overtake Mode: This supersedes the current DRS. It provides a surge of additional ERS power accessible when a driver is within one second the leading car to assist with an overtake.
• Boost Mode: This is a driver-operated energy deployment from the energy recovery system that can be utilized during offensive or defensive moves. It delivers 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 restricted.

• Active Aerodynamics: Both the nose and rear wings change configuration – opening on the straights for reduced drag and higher speed, and angling down in the corners for optimal cornering performance.
• Recharge: Cars can recharge the energy store with regenerative braking, or during throttle lift at the straight's end or in sections where only reduced throttle is used.

What's Changing on the Cars?

The next-generation machines will be reduced in size and weight relative to current models, with a car length shortened by 200mm to 3,400mm, car width reduced by 100mm – down to 1,900mm – and the lowest permissible weight lowered by 30kg.

Total aerodynamic grip is projected to decrease by approximately fifteen to thirty percent, although squads will undoubtedly recover some as they refine their designs.

Aerodynamic drag has been slashed by 40%. The vehicles will utilize moveable wing elements – front and rear wings will adjust on the straight sections to improve speed and increase straightline speed and click back into place for peak handling.

Pirelli tyres will retain 18-inch wheel rims, but the tyres themselves will be reduced in width, by 25mm at the front and 30mm at the rear.

Power Unit Revolution

The new power units will have an near-equal balance in energy output by the internal combustion engine and the ERS, a rise from about 20% electrical this year.

The energy recovery system is streamlined through the elimination of the complex turbo energy recovery device, the sophisticated and pricey unit that recovered energy from the turbocharger.

All vehicles will be required to run on carbon-neutral fuel, produced using organic sources or lab-created processes.
