The world of Formula 1 has unveiled the simplified language that will be used to explain the advanced features of its new 2026 regulations.

The racing series is implementing what is considered the biggest rules overhaul in its illustrious history starting in 2026, featuring new chassis and engine rules and the compulsory introduction of eco-friendly fuels.

The new power units, which maintain the 1.6-litre V6 configuration, boast a substantially higher battery power, necessitating major innovations in the aero packages.

Throughout races, pilots will tactically deploy electrical energy – including during qualifying laps – to extract the peak performance.

Wide-ranging research were undertaken with a mix of viewers, including long-time followers and newcomers, to determine which terminology would aid comprehension of the central aspects of the 2026 changes.

The stated goal was to present a range of advanced new areas of the racing as easy to grasp as possible for the global fanbase.

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 straightforward terms that directly explain the primary purpose of the system.

What's the New Technology?

Regulators explain that competitors will have greater control to choose strategies regarding battery management, energy recovery, and saving energy.

The upcoming changes mandate a series of modes that will be visually displayed on television graphics to improve the audience's understanding of the strategic duel.

• Overtake Mode: This takes over from the existing Drag Reduction System. It provides a surge of additional ERS power available when a car is close behind the leading car to execute an overtake.
• Power Mode: This is a driver-operated power boost from the hybrid system that can be deployed for attack or defence. It grants the pilot maximum power at the click of a switch.

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

• Active Aero: Both the front and rear wings change configuration – flattening on the straights for minimal air resistance and higher speed, and angling down in the turns for peak grip.
• Recharge: Drivers can replenish their battery with regenerative braking, or during coasting at the conclusion of a straight or in sections where only reduced throttle is required.

What's Changing on the Cars?

The vehicles for the new era will be reduced in size and weight relative to current models, with a car length cut by 200mm to 3,400mm, width reduced by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

Total aerodynamic grip is projected to decrease by approximately fifteen to thirty percent, although constructors will inevitably claw this back as they develop their cars.

Drag has been reduced by 40%. The vehicles will employ moveable wing elements – both wings will open on the straight sections to cut resistance and boost top speed and revert into place for maximum cornering performance.

Pirelli tyres will keep 18-inch rims, but the rubber compounds will be reduced in width, by 25 millimetres on the front axle and 30mm at the rear.

2026 Engine Regulations

The new power units will have an roughly half-and-half distribution in energy output by the ICE and the ERS, a rise from about one-fifth electric power this year.

The ERS setup is made less complex through the deletion of the complex turbo energy recovery device, the complicated and costly unit that generated electricity from the turbo.

Cars will be obliged to compete on 100% sustainable fuel, created from plant-based materials or synthetic industrial processes.
