Formula 1 has introduced the new language that will be used to explain the technical complexities of its revolutionary 2026 regulations.

The racing series is implementing what is arguably the biggest technical shift in its competitive history for the 2026 campaign, featuring new chassis and engine rules and the mandatory use of eco-friendly fuels.

The revised engines, which maintain the hybrid V6 layout, boast a significantly increased electrical capacity, driving key advancements in the cars' aerodynamics.

Throughout races, drivers will strategically manage battery power – including during flying laps – to extract the peak result.

Wide-ranging research were carried out 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 stated goal was to render a range of advanced technical aspects of the competition as straightforward as possible for the broadest viewership.

Consequently, initial designations for some systems – such as "modes labelled X and Z" for the adjustable aero – have been discarded in favor of descriptive names that clearly indicate the actual function of the system.

What's the New Technology?

Regulators explain that racers will have greater control to determine tactics regarding energy deployment, harvesting, and efficiency.

The upcoming changes introduce a set of functions that will be clearly indicated on TV overlays to improve the viewers' comprehension of the on-track action.

• Attack Mode: This replaces the present overtaking aid. It provides a short boost of battery power accessible when a car is close behind the leading car to assist with an overtaking maneuver.
• Power Mode: This is a manual energy deployment from the energy recovery system that can be utilized during offensive or defensive moves. It grants the pilot maximum power at the activation of a control.

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

• Active Aerodynamics: Both the nose and rear wings change configuration – flattening on the straights for minimal air resistance and higher speed, and closing in the corners for maximum downforce.
• Recharge: The system can replenish their battery with energy harvested under braking, or during coasting at the straight's end or in sections where only partial power is used.

What's Changing on the Cars?

The 2026 cars will be more compact and lighter than this year, with a wheelbase shortened by 200mm to 3,400mm, car width cut by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

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

Air resistance has been cut by 40%. The vehicles will utilize active aerodynamics – both wings will open on the straight sections to reduce drag and enhance velocity and click back into place for peak handling.

Pirelli tyres will keep the current rim size, but the actual tyres will be reduced in width, by 25mm at the front and three centimetres on the rear.

2026 Engine Regulations

The new power units will have an near-equal balance in energy output by the internal combustion engine and the electrical system, up from about 20% electrical this year.

The energy recovery system is made less complex through the removal of the Motor Generator Unit – Heat, the complicated and costly unit that recovered energy from the turbo.

All vehicles will be obliged to compete on fully sustainable fuel, produced using biomass or synthetic industrial processes.
