The world of Formula 1 has revealed the official vocabulary that will be used to reference the intricate details of its revolutionary 2026 rulebook.

The racing series is embarking on what is arguably the most significant regulation change in its competitive history starting in 2026, featuring new chassis and engine rules and the compulsory introduction of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which maintain the 1.6-litre V6 configuration, boast a significantly increased battery power, necessitating key advancements in the cars' aerodynamics.

Throughout races, pilots will tactically deploy ERS energy – potentially on hot laps – to secure the optimal lap time.

Extensive fan consultation were undertaken with a diverse audience, including long-time followers and newcomers, to understand which phrases would aid comprehension of the key features of the new regulations.

The key objective was to make a range of advanced new areas of the racing as accessible as possible for the broadest viewership.

Consequently, initial designations for certain devices – such as "modes labelled X and Z" for the moveable wings – have been phased out in favor of straightforward terms that clearly indicate the actual function of the technology.

Exploring the New Tech

The FIA states that drivers will have greater control to choose strategies regarding power usage, energy recovery, and efficiency.

The upcoming changes mandate a range of settings that will be clearly indicated on broadcast screens to enhance the fans' insight of the race battle.

• Overtake Mode: This replaces the existing Drag Reduction System. It provides a burst of extra electrical energy available when a competitor is close behind the leading car to assist with an pass.
• Power Mode: This is a on-demand battery discharge from the energy recovery system that can be deployed for offensive or defensive moves. It grants the pilot maximum power at the push of a button.

Both of these strategic tools will have to be deployed strategically, as the total energy is capped.

• Active Aero: Both the car's wings move automatically – spreading on the high-speed sections for minimal air resistance and higher speed, and angling down in the bends for peak grip.
• Battery Recharge: The system can recharge the energy store with regenerative braking, or during throttle lift at the conclusion of a straight or in corners where only partial power is applied.

2026 Car Specifications

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

Total aerodynamic grip is projected to decrease by approximately 15-30%, although squads will naturally regain performance as they refine their designs.

Aerodynamic drag has been reduced by 40%. The vehicles will feature adjustable aero systems – both wings will open on the straights to reduce drag and boost top speed and revert into place for peak handling.

Tyres will keep 18-inch rims, but the tyres themselves will be reduced in width, by 25 millimetres on the front axle and three centimetres on the rear.

2026 Engine Regulations

The 2026 engines will have an near-equal balance in power produced by the petrol engine and the ERS, a rise from about one-fifth electric power this year.

The hybrid system is streamlined through the deletion of the MGU-H, the sophisticated and pricey component that recovered energy from the exhaust turbo.

Cars will be obliged to compete on fully sustainable fuel, manufactured from organic sources or synthetic industrial processes.
