Earlier quoted context omitted.
The Nissan Leaf is a hatchback. The Tesla Model S is a hatchback. So is the Y. You might be right about real Amuricuns but the EV buying segment rather likes hatchbacks. With the exception of one SUV, which I did not like, every car I've ever owned since my first Honda Civic has been a hatchback.
Oh, Americans actually like vehicles that happen to have a large hatch in the back, but they do not like cars that are shaped like hatchbacks. The Model S is shaped like a sports sedan. It does not look like a hatchback.
If I had to guess, what you think of as "looks like a hatchback" is actually 'two-box' while "shaped like a sedan" is 'three-box.' Three-box hatchbacks have been around for decades though.
