When a vehicle is moving, air turbulence occurs on its surface – a quiet normal process in aerodynamics. The air flap control (“Active Grille Shutter”). If the air flaps are closed, air flow around the vehicle is improved and turbulence is reduced, thus significantly reducing fuel consumption and CO2 emissions.

Depending on the driving situation, the Active Grille Shutter closes or opens the air flaps automatically and guarantees optimum driving conditions. A positive side-effect of this system is the regulation of heat in the engine compartment – depending on requirements and demand, the hot air remains in the engine compartment or is dissipated.

Smart Actuators for active grill shutter flaps adjustment and thus contributes to the reduction of fuel consumption and CO2 emissions of vehicles.

The active grill shutter flap adjustment allows the air flow to be controlled in a targeted manner and improves the aerodynamics of the vehicle. In addition, closing the air flaps during the cold start phase accelerates the engine's heating up.
