F1 has revealed the simplified vocabulary that will be used to reference the intricate details of its upcoming 2026 technical rules.

The racing series is introducing what is arguably the biggest technical shift in its competitive history for the 2026 campaign, featuring new chassis and engine rules and the required adoption of fully sustainable fuels.

The revised engines, which maintain the hybrid V6 layout, boast a greatly enhanced energy storage, driving key advancements in the aero packages.

Throughout races, competitors will strategically manage battery power – potentially on qualifying laps – to achieve the peak performance.

Extensive fan consultation were conducted with a mix of viewers, including new, casual and core fans, to understand which terms would improve understanding of the central aspects of the upcoming rules.

The stated goal was to make a range of advanced new areas of the competition as straightforward as possible for the broadest viewership.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the adjustable aero – have been phased out in preference for intuitive labels that succinctly convey the actual function of the technology.

Key Technical Innovations

Regulators explain that drivers will have increased agency to determine tactics regarding battery management, regeneration, and saving energy.

The upcoming changes introduce a range of settings that will be clearly indicated on TV overlays to aid the fans' insight of the race battle.

• Passing Mode: This supersedes the existing Drag Reduction System. It provides a short boost of battery power available when a car is close behind the car ahead to assist with an overtaking maneuver.
• Power Mode: This is a on-demand energy deployment from the ERS that can be deployed for offensive or defensive moves. It delivers the driver full engine and battery energy at the click of a switch.

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

• Adjustable Aero: Both the car's wings adjust their angles – spreading on the long straight sections for minimal air resistance and higher speed, and angling down in the corners for peak grip.
• Energy Harvesting: The system can replenish their battery with regenerative braking, or during throttle lift at the end of straights or in certain corners where only reduced throttle is required.

2026 Car Specifications

The next-generation machines 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 reduced by 30kg.

Overall downforce is projected to decrease by approximately 15-30%, although constructors will naturally regain performance as they refine their designs.

Drag has been cut by 40%. The vehicles will utilize active aerodynamics – front and rear wings will adjust on the straights to reduce drag and boost top speed and return into place for maximum cornering performance.

Pirelli tyres will keep 18-inch rims, but the tyres themselves will be narrower, by 25 millimetres on the front axle and three centimetres on the rear.

What's Changing in the Engines?

The revised hybrid units will have an approximate 50-50 split in energy output by the ICE and the ERS, a rise from about 20% battery contribution this year.

The ERS setup is made less complex through the deletion of the MGU-H, the complicated and costly device that generated electricity from the exhaust turbo.

Every car on the grid will be obliged to compete on carbon-neutral fuel, created from organic sources or synthetic industrial processes.
