Active Aerodynamics
Active aerodynamics are parts that move automatically, such as rising spoilers or opening grille shutters, to adjust airflow to driving conditions.
What is Active Aerodynamics?
Active grille shutters close at speed to cut drag and open when cooling is needed. Rising rear spoilers deploy above a set speed. Some cars use moving flaps as an air brake under hard braking. Closing grille shutters on the motorway can reduce consumption noticeably at higher speeds.
How it works
Motors or actuators controlled by the car’s computer change the position of aero parts based on speed and temperature.
Why it matters for your car
A stuck shutter or spoiler can trigger a warning or affect cooling. Keep moving parts clean, especially after winter driving.
