Formula 1 and the FIA have published official definitions for key terms that will be used under the 2026 sporting and technical regulations. These terms describe specific systems and functions related to energy deployment, overtaking aids, aerodynamic control, and energy recovery. The definitions form part of the regulatory documentation released ahead of the 2026 season.
Boost Button refers to the control on the steering wheel that drivers will use to activate stored energy deployment from the power unit. Activation of the Boost Button changes the power unit’s output settings according to pre-set configurations. The function can be engaged at the driver’s discretion and is linked to stored electrical energy and engine output.
Overtake Mode is defined as the term replacing the former drag reduction system in official language. It is available only when a driver is within one second of the car ahead at a designated detection point. In this situation a driver can deploy additional stored energy for longer-sustained power delivery. The effect is intended to assist overtaking attempts by increasing the electrical power available for the next lap.
Recharge describes the process by which a car’s battery is charged using recovered energy. This can occur under braking, during partial throttle lift-off, or through specific energy recovery events defined in the power unit regulations. Recharge may be controlled automatically by the car’s electronic systems or triggered by certain driving behaviors.
Active Aero refers to movable aerodynamic elements on both front and rear wings that adjust depending on track conditions. These components operate in different positions for cornering and low-drag configurations. Drivers control Active Aero manually, and the system functions in conjunction with other aerodynamic regulations to alter wing angle for varying downforce and drag levels during a lap.
The new terminology aligns with broader changes to the 2026 power unit and aerodynamic rules set by the FIA in coordination with Formula 1. Under these regulations, cars will feature revised aerodynamic profiles, movable wing systems, and updated hybrid power unit structures. The terminology update ensures that the language used in technical briefings, broadcasts, and official documentation reflects the structural changes to the cars and racing systems.
Language changes were introduced as part of the regulatory package that accompanies the overhauled technical framework for 2026. These definitions are now part of the official glossary that teams, officials, media, and fans will reference during race weekends and in ongoing technical communication.
