The world of Formula 1 has unveiled the new terminology that will be used to describe the intricate details of its revolutionary 2026 regulations.

The racing series is embarking on what is considered the largest technical shift in its long history next season, featuring fresh chassis and power unit regulations and the mandatory use of eco-friendly fuels.

The revised engines, which keep the 1.6-litre V6 configuration, boast a substantially higher electrical capacity, necessitating key advancements in the cars' aerodynamics.

Over a race distance, pilots will tactically deploy battery power – including during hot laps – to achieve the optimal performance.

Wide-ranging research were undertaken with a mix of viewers, including dedicated enthusiasts and casual observers, to understand which phrases would make things clearer of the central aspects of the new regulations.

The key objective was to make a set of intricate features of the competition as easy to grasp as possible for the widest audience.

Consequently, older technical labels for some systems – such as "alphabetical mode names" for the adjustable aero – have been discarded in preference for intuitive labels that directly explain the real-world effect of the innovation.

What's the New Technology?

According to rule-makers that racers will have more power to determine tactics regarding energy deployment, regeneration, and efficiency.

The 2026 rules introduce a series of modes that will be shown on broadcast screens to improve the audience's understanding of the strategic duel.

• Attack Mode: This takes over from the present overtaking aid. It provides a short boost of battery power deployable when a competitor is close behind the leading car to execute an overtaking maneuver.
• Power Mode: This is a manual power boost from the ERS that can be deployed for attack or defence. It provides the driver peak output at the push of a button.

Both of these key functions will have to be used with calculation, as the total energy is restricted.

• Active Aero: Both the nose and rear wings adjust their angles – spreading on the long straight sections for low aerodynamic resistance and top speed, and sealing in the bends for peak grip.
• Energy Harvesting: Cars can recharge the energy store with regenerative braking, or during throttle lift at the straight's end or in certain corners where only limited engine output is applied.

What's Changing on the Cars?

The next-generation machines will be smaller and lighter than this year, with a distance between axles cut by 200mm to 3,400mm, width cut by 100mm – down to 1,900mm – and the car weight reduced by 30kg.

Overall downforce is anticipated to be reduced by approximately 15-30%, although squads will undoubtedly recover some as they develop their cars.

Air resistance has been slashed by 40%. The cars will employ active aerodynamics – front and rear wings will open on the straights to reduce drag and boost top speed and click back into place for optimal grip in corners.

Wheels will keep 18-inch wheel rims, but the actual tyres will be reduced in width, 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 battery and motor, a rise from about one-fifth electric power this year.

The energy recovery system is simplified through the deletion of the Motor Generator Unit – Heat, the intricate and expensive device that recovered energy from the turbocharger.

Cars will be required to run on 100% sustainable fuel, manufactured from plant-based materials or synthetic production methods.
