I know that the 2013+ Fusions have grill shutters that are designed to reduce drag at speed, and are also closed when the engine is cold to reduce the amount of time the engine needs to run simply to come up to operating temperature (and thus minimize emissions). However, I don't know exactly where they are located - or what they look like. Does anyone have a picture of the mechanism? Any experience with it? Can you notice it opening/closing (i.e., is there an audible noise when engaged/dis-engaged)?
