The world of Formula 1 has unveiled the official terminology that will be used to describe the technical complexities of its upcoming 2026 regulations.

The championship is embarking on what is potentially the biggest regulation change in its long history starting in 2026, featuring fresh chassis and power unit regulations and the required adoption of fully sustainable fuels.

The revised engines, which keep the 1.6-litre V6 turbo hybrid, boast a significantly increased electrical capacity, driving key advancements in the cars' aerodynamics.

Throughout races, pilots will tactically deploy ERS energy – potentially on qualifying laps – to achieve the optimal lap time.

Wide-ranging research were conducted with a diverse audience, including dedicated enthusiasts and casual observers, to identify which phrases would aid comprehension of the key features of the new regulations.

The primary aim was to render a series of complex technical aspects of the competition as straightforward as possible for the global fanbase.

Consequently, previous placeholder terms for some systems – such as "modes labelled X and Z" for the adjustable aero – have been phased out in favor of straightforward terms that succinctly convey the actual function of the system.

Exploring the New Tech

According to rule-makers that drivers will have increased agency to choose strategies regarding battery management, energy recovery, and efficiency.

The 2026 rules mandate a range of settings that will be shown on television graphics to enhance the fans' insight of the on-track action.

• Passing Mode: This replaces the current DRS. It provides a surge of additional ERS power deployable when a car is close behind the leading car to facilitate an overtake.
• Boost Mode: This is a on-demand power boost from the ERS that can be utilized during attack or defence. It grants the pilot maximum power at the push of a button.

Both of these key functions will have to be used with calculation, as the available electrical charge is restricted.

• Active Aerodynamics: Both the car's wings move automatically – flattening on the long straight sections for reduced drag and increased velocity, and sealing in the bends for peak grip.
• Battery Recharge: Cars can recharge the energy store with energy harvested under braking, or during coasting at the straight's end or in corners where only limited engine output is applied.

Car Design Evolution

The 2026 cars will be more compact and lighter 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 minimum weight decreased by 30kg.

Overall downforce is projected to decrease by approximately a significant margin, although squads will undoubtedly recover some as they refine their designs.

Drag has been reduced by 40%. The vehicles will employ active aerodynamics – both wings will adjust on the straight sections to reduce drag and increase straightline speed and return into place for maximum cornering performance.

Wheels will retain 18-inch rims, but the tyres themselves will be narrower, by 25mm at the front and 30 millimetres on the rear axle.

Power Unit Revolution

The 2026 engines will have an near-equal balance in energy output by the ICE and the ERS, increasing from about one-fifth electric power under present rules.

The energy recovery system is simplified through the elimination of the MGU-H, the complicated and costly device that harvested power from the exhaust turbo.

All vehicles will be required to run on carbon-neutral fuel, manufactured from biomass or synthetic industrial processes.
