2023 Porsche 911 GT3 RS Active Aero Rear Wing in Action

Porsche Active Aerodynamics (PAA) adapts the aerodynamic properties of the vehicle precisely to the driving situation, speed and selected driving programme. The basis for a significant performance boost is the concept of a central radiator – an idea that was first used in the Le Mans class-winning 911 RSR and subsequently in the 911 GT3 R. Instead of the three-radiator layout seen in previous cars, the new 911 GT3 RS relies on a large, angled centre radiator in the car’s nose, positioned where the luggage compartment is located on other 911 models. This makes room for active aerodynamic elements to be integrated into the freed-up space.

PAA can control the wing position instantly, automatically and continuously. This enables as much downforce as possible to be generated on the racetrack during high-speed manoeuvres with extreme lateral acceleration. The wing is adjusted synchronously. The control electronics make use of numerous vehicle parameters. In extreme areas, it can also limit downforce, ensuring that it does not exceed the load limit on the tyres, for example.

By default, the low downforce level is enabled. The wings are arranged flat here to facilitate the minimum cw value (0.39) and maximum speed (296 km/h). This level is particularly suitable for long straight lines on the racetrack as well as for everyday driving.

The high-downforce level automatically regulates the wing position according to the driving situation. This dynamic setup is designed to create as much downforce as possible. The aim is to achieve a very steep wing position so that the new 911 GT3 RS can unleash its maximum performance on the racetrack.
