- one extra inch of ground clearance - hatchback instead of trunk - a few more inches of head/leg room
And because of that, it's an "SUV".
This positioning is not at all exclusive to Tesla, but it's still annoying. Call them "CUVs", "crossovers", "lifted, less-practical wagons", whatever.
Ultimately the problem is that Americans all want "SUVs", but most (rightfully so) don't want the downsides of an actual body-on-frame SUV (poor mileage, ride, packaging), or have any need for off-road capability. As a result, our most competitive auto segments are "lifted, less-practical wagon/minivan". Sigh.
