A module with two louvers, which are opened and closed by small electric motors as required, sits between the Singleframe and the radiators. Each louver is made up of three slats. Guiding elements and molded-foam parts seal off the area in front of the controllable cool-air inlet so that the incoming air does not generate any swirl. At the same time, the foam absorbs impact energy with a collision at low speed, thus also contributing to pedestrian protection.

The roll stiffness, lateral stiffness, and the rubber bushing comfort related behavior are all tuned in accordance with the customers wishes.
