I noticed that most modern cars have similarly shaped wheel arches these days. Examples:

In opposition to the old style:

The difference?
Nearly all new cars have wheel arches finished with vertical surface which is cut from the rest by a sharp edge. I wonder if it's just some concept of styling or is it somehow related to aerodynamics and fuel economy?
If it had sth to do with FE, I think I could try to adopt it in my Benz...
I hope You will understand sth from the pics. If not, I'll try to draw a scheme and drop it here.
