F1 has revealed the simplified terminology that will be used to explain the intricate details of its upcoming 2026 regulations.

The championship is implementing what is arguably the biggest rules overhaul in its long history for the 2026 campaign, featuring new chassis and engine rules 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 battery power, driving significant developments in the vehicles' aerodynamic design.

Over a race distance, drivers will tactically deploy battery power – potentially on qualifying laps – to achieve the peak performance.

Broad surveys were conducted with a diverse audience, including new, casual and core fans, to determine which phrases would aid comprehension of the main elements of the upcoming rules.

The stated goal was to render a series of complex technical aspects of the competition as easy to grasp as possible for the broadest viewership.

Consequently, previous placeholder terms for certain devices – such as "modes labelled X and Z" for the adjustable aero – have been discarded in favour of descriptive names that succinctly convey the primary purpose of the system.

Key Technical Innovations

Regulators explain that racers will have increased agency to determine tactics regarding battery management, harvesting, and efficiency.

The upcoming changes mandate a range of settings that will be visually displayed on TV overlays to aid the fans' insight of the on-track action.

• Attack Mode: This supersedes the existing Drag Reduction System. It provides a surge of additional ERS power deployable when a car is within one second the leading car to facilitate an pass.
• Extra Push Mode: This is a driver-operated energy deployment from the energy recovery system that can be used in overtaking or defending. It grants the driver maximum power at the push of a button.

Both of these strategic tools will have to be managed carefully, as the total energy is restricted.

• Active Aero: Both the front and rear wings adjust their angles – flattening on the high-speed sections for reduced drag and higher speed, and angling down in the corners for maximum downforce.
• Battery Recharge: Cars can harvest energy with regenerative braking, or during coasting at the end of straights or in corners where only partial power is applied.

What's Changing on the Cars?

The 2026 cars will be smaller and lighter than this year, with a car length cut by 200mm to 3,400mm, overall width narrowed by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

Total aerodynamic grip is expected to drop by approximately fifteen to thirty percent, although constructors will undoubtedly recover some as they develop their cars.

Air resistance has been reduced by 40%. The cars will feature adjustable aero systems – front and rear wings will move on the straight sections to cut resistance and enhance velocity and revert into place for maximum cornering performance.

Wheels will retain 18-inch rims, but the actual tyres will be slimmer, by 25 millimetres on the front axle and 30 millimetres on the rear axle.

What's Changing in the Engines?

The 2026 engines will have an near-equal balance in horsepower generated by the petrol engine and the electrical system, increasing from about 20% battery contribution this year.

The ERS setup is streamlined through the elimination of the MGU-H, the complicated and costly component that recovered energy from the turbocharger.

Every car on the grid will be mandated to operate on fully sustainable fuel, manufactured from plant-based materials or synthetic production methods.
