Formula 1 has unveiled the simplified terminology that will be used to explain the technical complexities of its upcoming 2026 rulebook.

The racing series is implementing what is potentially the biggest technical shift in its competitive history starting in 2026, featuring revised car and engine specifications and the mandatory use of eco-friendly fuels.

The revised engines, which keep the 1.6-litre V6 configuration, boast a substantially higher energy storage, driving key advancements in the vehicles' aerodynamic design.

Over a race distance, competitors will strategically manage battery power – including during qualifying laps – to achieve the peak performance.

Broad surveys were undertaken with a wide range of fans, including long-time followers and newcomers, to identify which phrases would improve understanding of the key features of the 2026 changes.

The primary aim was to present a series of complex new areas of the competition as straightforward as possible for the global fanbase.

Consequently, initial designations for certain devices – such as "x-mode and z-mode" for the moveable wings – have been abandoned in favor of intuitive labels that directly explain the real-world effect of the innovation.

Exploring the New Tech

According to rule-makers that competitors will have greater control to choose strategies regarding power usage, harvesting, and efficiency.

The 2026 rules feature a set of functions that will be shown on broadcast screens to aid the audience's understanding of the strategic duel.

• Attack Mode: This takes over from the present overtaking aid. It provides a surge of additional ERS power available when a competitor is close behind the vehicle in front to facilitate an overtaking maneuver.
• Boost Mode: This is a on-demand power boost from the energy recovery system that can be deployed for overtaking or defending. It provides the driver maximum power at the push of a button.

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

• Active Aerodynamics: Both the car's wings change configuration – opening on the high-speed sections for minimal air resistance and increased velocity, and closing in the bends for optimal cornering performance.
• Energy Harvesting: Drivers can harvest energy with power recovered from braking, or during throttle lift at the conclusion of a straight or in certain corners where only limited engine output is required.

2026 Car Specifications

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

Total aerodynamic grip is anticipated to be reduced by approximately a significant margin, although squads will naturally regain performance as they refine their designs.

Drag has been slashed by 40%. The vehicles will feature moveable wing elements – both wings will open on the straights to reduce drag and enhance velocity and revert into place for optimal grip in corners.

Pirelli tyres will continue to use the current rim size, but the tyres themselves will be reduced in width, by a quarter-centimetre on the front and 30mm at the rear.

Power Unit Revolution

The 2026 engines will have an approximate 50-50 split in horsepower generated by the petrol engine and the battery and motor, a rise from about 20% electrical in the current formula.

The energy recovery system is simplified through the deletion of the Motor Generator Unit – Heat, the intricate and expensive unit that harvested power from the turbo.

Cars will be obliged to compete on carbon-neutral fuel, created from biomass or synthetic production methods.
