Ok, to be more accurate a number of variables come together with drag. If you are buying a crossover, you're probably interested in a roomy interior, safety, a higher vantage point for visibility, a short hood for easy maneuvering and again visibility. Put all these things together, and the basic shape is that of an enlarged classic mini cooper. Then put this somewhat large, somewhat tall vehicle in a wind tunnel and sculpt it for efficiency, and you arrive at today's crossover. You're right that aerodynamics does not leave us with only one possible body. We still have sports cars, vans, sedans, etc, each with a basic shape dictated by basic goals. But drag sculpts the shapes that go into the wind tunnels in generally uniform ways, because the wind treats a Dodge the same as a Ford.
