I had no idea there was such a variety. I think you're on to something. On the other hand, maybe not!
With very little to go on I am placing my bets that it will be a scaled down Model S which Elon has hinted at. This drawing would be consistent with the Model S and Model X and would continue the Tesla "look".
I like that look (how could I not, it looks like a Tesla) but I am worried about the back headroom in smaller/shorter version of a Model S. It might make more sense to make a smaller Model X (which this kind of is). The roof line would have to be kept higher and slope more behind the rear seats. I don't think this will affect the look too much. Then of course there is the question of falcon doors covering the front and rear seats. I think it would be cool but also annoying as a drive'rs door as you open those much more than the rear one. Perhaps doors that slide away from each other (driver door slides forward, rear door slides backwards). I like the fact that they would stay close to the car. My current two door car has large doors which is nice when you have a lot of room but hard to get in/out of when you are in tight places.
We made a Veloster comparison in the 2 door thread as well: Gen3 2-door coupe styling ideas - Page 13
I like the idea of a Tesla in the shape of a scaled-down Model X. Having the rear extra headroom and a taller hatch area would be useful for people transitioning away from both compact/midsize family cars and CUVs.
