Can someone please explain this? Thanks.

Just the Facts:Active grille shutters are popping up on a number of new models, including the 2015 Ford Mustang.The shutters open and close automatically to control airflow, reducing aerodynamic drag and improving fuel efficiency.

Thanks Brent

Your Welcome [emoji106] Also check YouTube there are a bunch of videos.

That pic and graphic from the Edmunds site kinda implies the shutters on the mustang are in the fog light area. I wonder how accurate that is?

I think they used the wrong pic

This is the correct image for active grille shutters. The image from the Edmunds post illustrates the wheel air curtains. The shutters are mounted behind the grille and are opened and closed based on engine temperature and vehicle speed.

Air flowing through the engine bay is a huge source of drag so at at higher speeds as long as the engine temperature is below a threshold, the shutters automatically close forcing the air over and around the body. At lower speeds where aero drag is not as important, the shutters open to enable the air flow to keep temperatures down.

Will the GTs have this or just EB?

I can't see how these active grills help aero. I have them in a 2014 Focus. When they close at interstate speed all they do is create a wall that traps air between the outside bumper grill area and the active grill. They are not designed correctly to direct air under the car, and if they are doing that then that provide lift to the front end, the opposite of what the rest of the car is doing. For this to work correctly, these active grills need to be angled, not vertical to the ground IMHO.

That is not part of the grill system, that area is open allowing air flow to the wheel area... minor is cooling but also to disrupt the air in the wells minimizing drag as well... there is a pocket off air that develops at the front of the wheels... mostly at faster speeds

Ecoboost only.

You're wrong. It doesn't much matter where the shutters are located or what angle they are at. Closing them creates a bubble of air ahead of the car which forces the air over the top and around the sides, the air underneath is limited by the splitter and air damn. There are there different versions of the air damn on the s550.

Here's a video of the Active Grill Shutters in action on a 2012 Focus. The name is a little decieving as they Don't Actually Attach to the Grill but to the Front of the Radiator behind the Grill.






And Here's another general video that explains how Active Grill Shutters work.
