wagon/hatch
If the pressure is different around the perimeter of the separation line,flow into a lower pressure area will introduce shear which can spin up into vortices which will absorb significant power.
The separation line also dictates the base pressure of the wake.
The station wagon would have a nice uniform pressure whereas is it is questionable for the other car.
