F1 has introduced the official language that will be used to reference the technical complexities of its upcoming 2026 technical rules.

The championship is implementing what is potentially 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 revised engines, which maintain the hybrid V6 layout, boast a greatly enhanced energy storage, requiring key advancements in the cars' aerodynamics.

During grand prix events, competitors will carefully oversee electrical energy – sometimes even qualifying laps – to secure the best performance.

Broad surveys were undertaken with a mix of viewers, including new, casual and core fans, to determine which terminology would improve understanding of the main elements of the 2026 changes.

The primary aim was to make a series of complex new areas of the sport as easy to grasp as possible for the global fanbase.

Consequently, initial designations for certain devices – such as "modes labelled X and Z" for the active aerodynamics – have been abandoned in favour of intuitive labels that directly explain the actual function of the system.

Exploring the New Tech

The FIA states that racers will have greater control to determine tactics regarding energy deployment, energy recovery, and saving energy.

The new regulations feature a range of settings that will be visually displayed on broadcast screens to aid the viewers' comprehension of the race battle.

• Overtake Mode: This takes over from the current DRS. It provides a short boost of battery power accessible when a driver is within one second the car ahead to assist with an pass.
• Extra Push Mode: This is a driver-operated battery discharge from the energy recovery system that can be deployed for offensive or defensive moves. It grants the driver peak output at the push of a button.

Both of these key functions will have to be managed carefully, as the total energy is capped.

• Adjustable Aero: Both the front and rear wings adjust their angles – spreading on the straights for low aerodynamic resistance and higher speed, and angling down in the corners for peak grip.
• Energy Harvesting: The system can harvest energy with regenerative braking, or during throttle lift at the straight's end or in sections where only partial power is required.

2026 Car Specifications

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

Cumulative downforce is anticipated to be reduced by approximately a significant margin, although constructors will undoubtedly recover some as they develop their cars.

Drag has been slashed by 40%. The vehicles will utilize adjustable aero systems – both wings will move on the straight sections to improve speed and increase straightline speed and click back into place for peak handling.

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

2026 Engine Regulations

The 2026 engines will have an near-equal balance in energy output by the ICE and the ERS, a rise from about 20% battery contribution under present rules.

The energy recovery system is made less complex through the deletion of the complex turbo energy recovery device, the intricate and expensive component that recovered energy from the exhaust turbo.

All vehicles will be required to run on 100% sustainable fuel, produced using organic sources or lab-created processes.
