2021 Porsche 911 Turbo S [UK]

More powerful, dynamic and comfortable than ever before: the new Porsche 911 Turbo S sets new standards in many areas. That is also true for the adaptive aerodynamics, which Porsche has further enhanced in its flagship 911. Porsche Active Aerodynamics (PAA) adapts the aerodynamic characteristics of the vehicle even more precisely to the driving situation, speed and selected driving mode. PAA celebrated its world premiere in the previous generation of the 911 Turbo launched in 2014. All model lines from the 718 through to the Panamera and Taycan now feature active aerodynamic elements.

The active cooling air flaps are new. Together with the variable front spoiler lip as well as the extending and tilting rear wing, the new top-of-the-range model therefore features three active aerodynamic components. On top of the basic aerodynamic configurations of the 911 Turbo, namely PAA Speed and PAA Performance, this now permits realisation of an Eco configuration.

PAA has also been extended to include a Wet Mode function, which moves the aerodynamic balance towards the rear axle for greater driving stability in wet road conditions, as well as the airbrake function, which produces higher drag and greater downforce in the event of full braking at high speed and therefore results in a shorter braking distance and greater driving stability. PAA is also used for adaptation to the changed air flow around the vehicle when the sliding roof or convertible top is open. This means that there are a total of eight different aerodynamic configurations, which are each described by a specific combination of the active aerodynamic components.

Improvements have not just been made in adaptation to the specific requirements in driving operation, but also as regards the aerodynamic properties themselves: the newly designed active front spoiler and rear wing have increased the downforce by 15 percent to guarantee enhanced driving stability and dynamics at higher speeds. The maximum downforce in the Performance position (Sport Plus mode activated) is now around 170 kg.

The drag coefficient (cd) of the Porsche 911 Turbo S varies depending on the aerodynamic setting. The most efficient configuration with the minimum cd value of 0.33 is achieved with closed flaps and retracted front and rear spoilers.
