Porsche Active Aerodynamic (PAA) for different driving modes:

Porsche Active Aerodynamic (PAA) is a system of adjustable aerodynamic elements that provides a unique and variable aerodynamic response. The system works in three stages, switching automatically between optimum efficiency and maximum downforce, and working in harmony with the operating modes of the hybrid drive.

In “Race” mode, the retractable rear wing is set to a steep angle to generate high downforce at the rear axle. The spoiler, which is positioned between the two wing supports at the trailing edge of the airflow, also extends. Two adjustable air flaps are opened in the underbody in front of the front axle, directing some of the air into the diffuser channels of the underbody structure to also produce a “ground effect” at the front axle.

In “Sport” mode, the aerodynamics control system reduces the approach angle of the rear wing slightly, enabling a higher top speed. The spoiler remains extended but the aerodynamic flaps in the underbody close, which also reduces aerodynamic drag and increases the potential vehicle speed. In “E” mode, the system focuses solely on low aerodynamic drag; the rear wing and spoiler are retracted and the underbody flaps are closed. Adjustable air intakes under the main headlights round off the adaptive aerodynamics system. When the vehicle is stationary and in “Race” or “Sport” mode, the intakes are opened to enable maximum cooling. In “E-Power” and “Hybrid” mode, the air intakes close as soon as the vehicle is driven off in order to keep aerodynamic drag to a minimum. They are not opened again until the vehicle reaches speeds of approximately 130 km/h or when cooling requirements are higher.
