Saw these posted up on
Mustang6g.
First video confirming there's a ecoboost turbo 4 cylinder Mustang coming.
The whine is definitely noticeable.
These were seen in Flagstaff Arizona, in case anyone here is near there and has a camera
OP:

I wonder if the next gen Camaro will have a turbo 4 to compete directly too.
