The world of Formula 1 has unveiled the simplified vocabulary that will be used to explain the intricate details of its revolutionary 2026 rulebook.

The sport is embarking on what is potentially the most significant regulation change in its long history starting in 2026, featuring new chassis and engine rules and the mandatory use of eco-friendly fuels.

The new power units, which keep the 1.6-litre V6 configuration, boast a significantly increased energy storage, necessitating significant developments in the vehicles' aerodynamic design.

During grand prix events, drivers will tactically deploy electrical energy – potentially on qualifying laps – to extract the peak lap time.

Wide-ranging research were undertaken with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which phrases would make things clearer of the key features of the 2026 changes.

The key objective was to render a series of complex technical aspects of the competition as straightforward as possible for the widest audience.

Consequently, older technical labels for some systems – such as "alphabetical mode names" for the moveable wings – have been phased out in favor of straightforward terms that directly explain the actual function of the innovation.

Exploring the New Tech

Regulators explain that racers will have greater control to determine tactics regarding energy deployment, harvesting, and efficiency.

The 2026 rules mandate a series of modes that will be clearly indicated on broadcast screens to aid the fans' insight of the strategic duel.

• Attack Mode: This takes over from the present overtaking aid. It provides a burst of extra electrical energy available when a competitor is close behind the vehicle in front to facilitate an overtaking maneuver.
• Power Mode: This is a manual power boost from the ERS that can be used in overtaking or defending. It delivers the pilot full engine and battery energy at the push of a button.

Both of these strategic tools will have to be used with calculation, as the total energy is capped.

• Active Aerodynamics: Both the car's wings move automatically – spreading on the high-speed sections for reduced drag and top speed, and closing in the turns for peak grip.
• Energy Harvesting: Drivers can recharge the energy store with power recovered from braking, or during coasting at the straight's end or in corners where only limited engine output is applied.

What's Changing on the Cars?

The next-generation machines will be reduced in size and weight than this year, with a car length shortened by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the lowest permissible weight reduced by 30kg.

Overall downforce is expected to drop by approximately 15-30%, although teams will inevitably claw this back as they optimize their packages.

Drag has been reduced by 40%. The vehicles will utilize adjustable aero systems – both wings will open on the straights to improve speed and enhance velocity and revert into place for optimal grip in corners.

Pirelli tyres will retain 18-inch rims, but the rubber compounds will be narrower, by a quarter-centimetre on the front and three centimetres on the rear.

Power Unit Revolution

The new power units will have an approximate 50-50 split in horsepower generated by the ICE and the battery and motor, increasing from about 20% electrical in the current formula.

The hybrid system is simplified through the elimination of the Motor Generator Unit – Heat, the sophisticated and pricey device that generated electricity from the turbo.

Cars will be obliged to compete on fully sustainable fuel, created from biomass or synthetic production methods.
