When the car is at a standstill, three louvres are opened in each front-end air intake by an actuator. If there is no extra need for more cooling air, they close at speeds above 15 km/h and open over several stages starting at 160 km/h, or starting at 120 km/h when the convertible hood is stowed or the sliding sunroof is open. When the louvres are closed, airflow around the front end is improved, and this lowers air drag and lift at the front axle.

The active aerodynamic system adjusts the angle of attack of the rear spoiler according to the flap position, to assure finely balanced lift at the front and rear axles in every situation. The variable spoiler performs another task with the introduction of turbocharged engines: by adjusting the angle of attack, the air stream is redirected so that more air enters the intake ports for intercooling. When outside temperatures are high, the spoiler can even be extended starting at 60 km/h to increase the throughput of intercooling air.
