Why is it a sedan? The model S is a hatchback and the overall aesthetic is the same but the S has more utility in that sense. Also, it has a better drag coefficient now than the 3 so I literally just don't understand why it isn't a hatchback.
Doesn't need to have that design that creates a low pressure behind the entire back of the car. Just don't know why the S has a hatch and the 3 doesn't.
Anyone know?
Probably because of the fact that others mentioned, that the hatchback design in some other vehicles has less headroom. The BMW 3 series is a sedan, and the 4 series is a hatchback, and the 4 series has a LOT less room in the back (but is more functional because of the hatchback design. If tesla offered both a hatchback and non hatchback model 3, I would have bought the hatchback. They didnt though, and I dont particularly like the look of the model Y so wouldnt get one just because it has a hatchback.
With all that being said "why isnt it XXX" is sort of like asking....."why are there oreos thins, regular and doublestuff?" (or any other question related to a manufacturer making a design decision).
