Last year I went form a SUV to a sedan, and while I'm happy, I certainly feel as if the space of even a smaller SUV or a wagon, or a hatchback, makes them more attractive. Certainly, I can't imagine a sedan design being that much more fuel efficient than a station wagon.
How did the sedan, wiht it's smaller cargo space, get to be so much more popular then wagons and hatchbacks(at least in the US)? Was it just easier to make and so the major auto makers made more of them cheaper?
For reference, a hatchback is considered a sedan which, per the linked Wikipedia article, is defined as
a passenger car in a three-box configuration with A, B & C-pillars and principal volumes articulated in separate compartments for engine, passenger and cargo.
