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

The championship is introducing what is arguably the most significant rules overhaul in its illustrious history starting in 2026, featuring fresh chassis and power unit regulations and the compulsory introduction of fully sustainable fuels.

The new power units, which retain the 1.6-litre V6 configuration, boast a greatly enhanced electrical capacity, requiring significant developments in the cars' aerodynamics.

During grand prix events, pilots will carefully oversee battery power – potentially on qualifying laps – to extract the best result.

Wide-ranging research were conducted with a diverse audience, including dedicated enthusiasts and casual observers, to understand which terms would aid comprehension of the main elements of the upcoming rules.

The stated goal was to make a range of advanced technical aspects of the racing as accessible as possible for the widest audience.

Consequently, previous placeholder terms for some systems – such as "x-mode and z-mode" for the moveable wings – have been abandoned in favour of intuitive labels that clearly indicate the primary purpose of the technology.

Exploring the New Tech

The FIA states that competitors will have more power to determine tactics regarding power usage, regeneration, and conservation.

The upcoming changes feature a range of settings that will be shown on television graphics to aid the fans' insight of the strategic duel.

• Overtake Mode: This takes over from the current DRS. It provides a burst of extra electrical energy deployable when a car is close behind the car ahead to execute an pass.
• Power Mode: This is a driver-operated power boost from the hybrid system that can be utilized during attack or defence. It grants the pilot peak output at the push of a button.

Both of these crucial modes will have to be deployed strategically, as the overall battery capacity is restricted.

• Active Aerodynamics: Both the front and rear wings change configuration – flattening on the high-speed sections for low aerodynamic resistance and increased velocity, and angling down in the corners for maximum downforce.
• Recharge: Drivers can replenish their battery with regenerative braking, or during partial power application at the end of straights or in corners where only limited engine output is used.

2026 Car Specifications

The next-generation machines will be smaller and lighter relative to current models, with a car length shortened by 200mm to 3,400mm, car width cut by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Overall downforce is expected to drop by approximately a significant margin, although squads will inevitably claw this back as they refine their designs.

Air resistance has been reduced by 40%. The cars will employ active aerodynamics – both wings will open on the straights to reduce drag and increase straightline speed and click back into place for peak handling.

Tyres will keep 18-inch rims, but the actual tyres will be slimmer, by 25mm at the front and 30 millimetres on the rear axle.

2026 Engine Regulations

The revised hybrid units will have an near-equal balance in energy output by the ICE and the electrical system, up from about 20% electrical under present rules.

The hybrid system is simplified through the removal of the MGU-H, the intricate and expensive device that recovered energy from the turbo.

Every car on the grid will be mandated to operate on 100% sustainable fuel, created from biomass or synthetic production methods.
