this post got me thinking, so today i was in a parking lot and i looked at all the designs " on display" it seems that newer cars (should be the most aero one's) have a bigger radiused transition from the roof to the side, aft of the front door. combining this with the csd image, this would aid the transition of the airflow back to the roof.

another small difference that would not stand out in a profile view comparison with older boxy designs.
