This is something of a surprise.It's Daniel Bournouli's Theorem in action.Pressures and velocities at play along the body.
There is a great CFD image of Ford's F-150 online and the streamlines are behaving in a similar fashion along the sides near the door.They tried 12-different side-view mirrors on the 2015 F-150.
Makes the camera systems all that more attractive.
The 'naked' T-100 absorbs 47-hp at 70-mph according to CAR and DRIVER testing,and the side mirrors are absorbing 1-hp at 75-mpg according to Tyler Stories Darko spreadsheet.
At Bonneville they let the guys delete the mirrors entirely.
