Remember this is a render, THIS cannot be stated enough. People believe this is exactly how the F80 will look. Subtle, but extreme changes can still be made. We still haven't seen the rear, other than with camo on (and it looks to be very similar to the F10 M5). The side views are just the artists' interpretation, and so is the side vent. Again, all based on the F10. If history repeats itself, all M cars have had different side vents, and so will this one. I doubt it'll be exactly like the F10's unless someone has mule shots that can prove me other wise. SCOTT26 in his post in this thread pretty much ruled out the power bulge... sorry M3 "purists".
