The world of Formula 1 has revealed the simplified terminology that will be used to reference the intricate details of its new 2026 technical rules.

The championship is embarking on what is potentially the biggest rules overhaul in its long history for the 2026 campaign, featuring new chassis and engine rules and the compulsory introduction of eco-friendly fuels.

The revised engines, which maintain the 1.6-litre V6 turbo hybrid, boast a greatly enhanced energy storage, requiring major innovations in the cars' aerodynamics.

Over a race distance, competitors will carefully oversee battery power – potentially on flying laps – to extract the best performance.

Broad surveys were undertaken with a wide range of fans, including long-time followers and newcomers, to identify which terminology would aid comprehension of the central aspects of the new regulations.

The primary aim was to render a series of complex new areas of the racing as easy to grasp as possible for the broadest viewership.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the moveable wings – have been abandoned in favor of straightforward terms that succinctly convey the actual function of the technology.

Exploring the New Tech

Regulators explain that competitors will have increased agency to determine tactics regarding battery management, energy recovery, and efficiency.

The new regulations introduce a set of functions that will be shown on broadcast screens to enhance the viewers' comprehension of the race battle.

• Passing Mode: This supersedes the current DRS. It provides a burst of extra electrical energy deployable when a competitor is within one second the vehicle in front to execute an overtake.
• Boost Mode: This is a driver-operated power boost from the hybrid system that can be utilized during overtaking or defending. It delivers the pilot peak output at the click of a switch.

Both of these strategic tools will have to be used with calculation, as the overall battery capacity is strictly limited.

• Active Aero: Both the car's wings adjust their angles – flattening on the long straight sections for reduced drag and top speed, and closing in the bends for peak grip.
• Energy Harvesting: Drivers can recharge the energy store with energy harvested under braking, or during coasting at the end of straights or in sections where only reduced throttle is used.

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, car width reduced by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.

Total aerodynamic grip is projected to decrease by approximately a significant margin, although teams will naturally regain performance as they develop their cars.

Air resistance has been slashed by 40%. The vehicles will feature adjustable aero systems – front and rear wings will open on the straight sections to improve speed and enhance velocity and revert into place for maximum cornering performance.

Pirelli tyres will keep the current rim size, but the tyres themselves will be narrower, by 25 millimetres on the front axle and three centimetres on the rear.

2026 Engine Regulations

The new power units will have an roughly half-and-half distribution in energy output by the petrol engine and the electrical system, up from about 20% battery contribution under present rules.

The hybrid system is streamlined through the elimination of the Motor Generator Unit – Heat, the complicated and costly unit that recovered energy from the turbocharger.

All vehicles will be obliged to compete on 100% sustainable fuel, created from plant-based materials or synthetic production methods.
