So the fender gills on the M4 bumper are different than the ones on the lower models. For some reason I just thought that the M4 model will have the carbon inserts on the grilles instead of the chrome finish.

The M4 still has the same aggressive hump on the hood

yea i think becasue of the angle the rendering isnt able to capture the fender flares right, they just look too flat. I really like the new M4 grill, reminds me off the side grills on the e46 M's

The grille is convex outwards a bit to make it slightly more aggressive.
