F1 has introduced the official language that will be used to describe the intricate details of its upcoming 2026 regulations.

The racing series is implementing what is arguably the largest technical shift in its long history starting in 2026, featuring fresh chassis and power unit regulations and the mandatory use of 100% sustainable fuels.

The new power units, which keep the hybrid V6 layout, boast a greatly enhanced battery power, requiring key advancements in the cars' aerodynamics.

Over a race distance, competitors will tactically deploy electrical energy – sometimes even flying laps – to extract the peak lap time.

Wide-ranging research were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which phrases would aid comprehension of the main elements of the 2026 changes.

The stated goal was to present a set of intricate new areas of the racing as accessible as possible for the broadest viewership.

Consequently, older technical labels for specific components – such as "alphabetical mode names" for the adjustable aero – have been phased out in favour of straightforward terms that directly explain the actual function of the technology.

What's the New Technology?

The FIA states that racers will have increased agency to make decisions regarding energy deployment, harvesting, and efficiency.

The new regulations feature a series of modes that will be visually displayed on television graphics to enhance the fans' insight of the race battle.

• Passing Mode: This replaces 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 assist with an overtaking maneuver.
• Extra Push Mode: This is a on-demand power boost from the ERS that can be used in attack or defence. It provides the pilot full engine and battery energy at the activation of a control.

Both of these key functions will have to be managed carefully, as the total energy is strictly limited.

• Adjustable Aero: Both the front and rear wings change configuration – opening on the long straight sections for minimal air resistance and top speed, and sealing in the turns for maximum downforce.
• Recharge: Cars can replenish their battery with regenerative braking, or during partial power application at the conclusion of a straight or in certain corners where only partial power is applied.

2026 Car Specifications

The 2026 cars will be smaller and lighter relative to current models, with a distance between axles reduced by 200mm to 3,400mm, overall width reduced by 100mm – down to 1,900mm – and the car weight reduced by 30kg.

Overall downforce is expected to drop by approximately fifteen to thirty percent, although squads will inevitably claw this back as they optimize their packages.

Air resistance has been reduced by 40%. The cars will feature adjustable aero systems – both wings will move on the straights to cut resistance and increase straightline speed and click back into place for peak handling.

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

Power Unit Revolution

The new power units will have an approximate 50-50 split in horsepower generated by the internal combustion engine and the electrical system, a rise from about one-fifth electric power this year.

The hybrid system is streamlined through the elimination of the Motor Generator Unit – Heat, the sophisticated and pricey device that harvested power from the turbocharger.

Cars will be required to run on fully sustainable fuel, created from biomass or lab-created processes.
