* Contemporary OEM separation is a fact for all production vehicles.
* What EcoModders would be interested in is, the degree of unnecessary separation, for a given body length, as a consequence of 'design' specification.
* 'Basic' profiles vs 'complex' profiles.
* Any grouping of vehicles of same frontal area will reveal the degree of separation as a function of drag coefficient.
* All else being equal, the vehicle with the highest top speed will possess the lowest degree of separation, the lowest drag coefficient, lowest fuel / energy consumption, highest fuel economy / range, and lowest emissions.
* The evidence is the drag coefficient, by default.
