The world of Formula 1 has unveiled the simplified terminology that will be used to explain the advanced features of its upcoming 2026 technical rules.

The sport is implementing what is arguably the largest rules overhaul in its illustrious history for the 2026 campaign, featuring fresh chassis and power unit regulations and the compulsory introduction of eco-friendly fuels.

The new power units, which retain the 1.6-litre V6 configuration, boast a substantially higher energy storage, driving major innovations in the aero packages.

Throughout races, pilots will strategically manage electrical energy – potentially on qualifying laps – to secure the best lap time.

Wide-ranging research were undertaken with a mix of viewers, including long-time followers and newcomers, to understand which phrases would make things clearer of the key features of the 2026 changes.

The key objective was to render a range of advanced features of the competition as accessible as possible for the widest audience.

Consequently, initial designations for specific components – such as "modes labelled X and Z" for the active aerodynamics – have been phased out in favour of straightforward terms that directly explain the real-world effect of the system.

Exploring the New Tech

The FIA states that competitors will have more power to determine tactics regarding energy deployment, harvesting, and efficiency.

The upcoming changes introduce a series of modes that will be visually displayed on TV overlays to enhance the viewers' comprehension of the strategic duel.

• Attack Mode: This replaces the present overtaking aid. It provides a surge of additional ERS power available when a car is within one second the leading car to assist with an overtaking maneuver.
• Boost Mode: This is a manual power boost from the ERS that can be deployed for attack or defence. It delivers the driver full engine and battery energy at the activation of a control.

Both of these strategic tools will have to be deployed strategically, as the available electrical charge is capped.

• Active Aerodynamics: Both the car's wings change configuration – flattening on the straights for low aerodynamic resistance and higher speed, and closing in the bends for peak grip.
• Energy Harvesting: Cars can recharge the energy store with regenerative braking, or during partial power application at the straight's end or in sections where only partial power is required.

What's Changing on the Cars?

The next-generation machines will be more compact and lighter compared to the 2025 spec, with a distance between axles reduced by 200mm to 3,400mm, overall width reduced by 100mm – down to 1,900mm – and the lowest permissible weight decreased 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 cut by 40%. The vehicles will feature moveable wing elements – both wings will adjust on the straights to reduce drag and boost top speed and click back into place for maximum cornering performance.

Tyres will continue to use the current rim size, but the tyres themselves will be reduced in width, by a quarter-centimetre on the front and 30mm at the rear.

Power Unit Revolution

The new power units will have an near-equal balance in power produced by the ICE and the electrical system, increasing from about 20% battery contribution under present rules.

The energy recovery system is simplified through the elimination of the MGU-H, the intricate and expensive device that recovered energy from the turbocharger.

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