The world of Formula 1 has introduced the simplified terminology that will be used to describe the advanced features of its upcoming 2026 regulations.

The racing series is introducing what is potentially the most significant technical shift in its long history starting in 2026, featuring new chassis and engine rules and the required adoption of fully sustainable fuels.

The new power units, which maintain the 1.6-litre V6 configuration, boast a substantially higher energy storage, necessitating significant developments in the cars' aerodynamics.

Throughout races, pilots will tactically deploy battery power – including during flying laps – to achieve the peak performance.

Wide-ranging research were conducted with a diverse audience, including dedicated enthusiasts and casual observers, to identify which terms would make things clearer of the main elements of the 2026 changes.

The key objective was to make a series of complex technical aspects of the racing as easy to grasp as possible for the widest audience.

Consequently, previous placeholder terms for some systems – such as "x-mode and z-mode" for the active aerodynamics – have been phased out in favor of descriptive names that succinctly convey the real-world effect of the technology.

Exploring the New Tech

Regulators explain that competitors will have increased agency to determine tactics regarding power usage, regeneration, and saving energy.

The 2026 rules introduce a set of functions that will be visually displayed on broadcast screens to enhance the audience's understanding of the race battle.

• Passing Mode: This supersedes the existing Drag Reduction System. It provides a short boost of battery power accessible when a competitor is within one second the vehicle in front to facilitate an overtaking maneuver.
• Power Mode: This is a on-demand energy deployment from the hybrid system that can be deployed for offensive or defensive moves. It delivers the driver maximum power at the activation of a control.

Both of these strategic tools will have to be used with calculation, as the total energy is strictly limited.

• Adjustable Aero: Both the car's wings adjust their angles – opening on the high-speed sections for minimal air resistance and higher speed, and sealing in the turns for optimal cornering performance.
• Recharge: The system can recharge the energy store with power recovered from braking, or during coasting at the conclusion of a straight or in sections where only reduced throttle is applied.

Car Design Evolution

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

Overall downforce is expected to drop by approximately fifteen to thirty percent, although constructors will undoubtedly recover some as they develop their cars.

Drag has been slashed by 40%. The cars will utilize active aerodynamics – front and rear wings will adjust on the straight sections to improve speed and increase straightline speed and return into place for peak handling.

Pirelli tyres will retain 18-inch rims, but the tyres themselves will be reduced in width, by 25mm at the front and 30mm at the rear.

2026 Engine Regulations

The new power units will have an near-equal balance in power produced by the internal combustion engine and the ERS, increasing from about 20% battery contribution in the current formula.

The hybrid system is made less complex through the elimination of the Motor Generator Unit – Heat, the sophisticated and pricey component that generated electricity from the turbo.

All vehicles will be required to run on 100% sustainable fuel, produced using plant-based materials or synthetic production methods.
