Formula 1 has introduced the official language that will be used to reference the advanced features of its revolutionary 2026 technical rules.

The sport is implementing what is potentially the most significant regulation change in its illustrious history for the 2026 campaign, featuring fresh chassis and power unit regulations and the compulsory introduction of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which keep the hybrid V6 layout, boast a significantly increased electrical capacity, necessitating major innovations in the vehicles' aerodynamic design.

Over a race distance, competitors will tactically deploy battery power – sometimes even flying laps – to secure the optimal result.

Broad surveys were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which phrases would make things clearer of the main elements of the new regulations.

The stated goal was to render a series of complex new areas of the competition as straightforward as possible for the widest audience.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the adjustable aero – have been phased out in favour of intuitive labels that directly explain the actual function of the technology.

What's the New Technology?

According to rule-makers that drivers will have greater control to choose strategies regarding power usage, energy recovery, and saving energy.

The new regulations feature a set of functions that will be visually displayed on broadcast screens to enhance the audience's understanding of the strategic duel.

• Attack Mode: This supersedes the current DRS. It provides a burst of extra electrical energy accessible when a car is less than a second the leading car to execute an pass.
• Power Mode: This is a on-demand battery discharge from the hybrid system that can be used in attack or defence. It grants the driver maximum power at the activation of a control.

Both of these key functions will have to be used with calculation, as the available electrical charge is capped.

• Active Aero: Both the front and rear wings move automatically – spreading on the high-speed sections for reduced drag and top speed, and angling down in the corners for maximum downforce.
• Battery Recharge: Cars can replenish their battery with energy harvested under braking, or during partial power application at the conclusion of a straight or in sections where only limited engine output is used.

2026 Car Specifications

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

Cumulative downforce is anticipated to be reduced by approximately 15-30%, although constructors will inevitably claw this back as they refine their designs.

Air resistance has been cut by 40%. The cars will feature adjustable aero systems – both wings will open on the straight sections to cut resistance and boost top speed and return into place for peak handling.

Tyres will retain 18-inch rims, but the actual tyres will be slimmer, by a quarter-centimetre on the front and 30 millimetres on the rear axle.

2026 Engine Regulations

The 2026 engines will have an roughly half-and-half distribution in horsepower generated by the internal combustion engine and the electrical system, up from about 20% electrical under present rules.

The energy recovery system is streamlined through the removal of the complex turbo energy recovery device, the intricate and expensive device that generated electricity from the turbo.

Every car on the grid will be mandated to operate on fully sustainable fuel, produced using biomass or synthetic industrial processes.
