I am going to guess (hope) this is a representative view of the interior as a few things don't quite make sense:
1) They kept the crappy, universally despised set-up for the front cup holders
2) No second row cup holders
3) The dash looks like an exact copy of the MS dash--the cars are different sizes, so its to like they can reuse parts, so assuming this is a photoshop hack
4) From what I can tell, the 2nd row does not seem to match Elon's hype, but that would not be the first time--I kinda like the pedestal thing and I wonder if there is more to it than just aesthetics.
Some thoughts:
Tesla only wants to gather option selections at this point. Which means that the other parts of the pictures that don't have options on them (e.g. center console) could be revealed to be different later. I don't think they are obliged to reveal every aspect of the car yet, and some of these photos may be photoshopped to disguise things - like extra features that will be included in Signature cars at no cost, but they don't want to reveal yet.
* My theory - the rear spoiler deploys when you put the car into Drive or Reverse. This is why they call it an "automatically retracting spoiler" and not an "automatically deploying spoiler." (Rather like the auto high-beam, which are in fact auto-dipping headlights.) In this way, you're never without a center brake light when you need it... but it is obscured when the spoiler is retracted. IMO this is not as elegant as it could have been. Why didn't they just put the center brake light at the top of the hatch, like the Model S ? You know, product family similarity an' all?
* No grab handles visible yet... I'm concerned what they think passengers will hold onto in this SUV when the vehicle is being flung around with Ludicrous aplomb.
* No obvious hooks/place to hang your dry-cleaning, though the available photos are admittedly scant
* Middle row seats have built-in seatbelts, a la Mercedes, very nice.
* Middle row seats slide forward and turn downwards, IMO, like
Gtoffo's graphic. They're at a 30-degree tilt or so when fully pushed forward. In addition to allowing easier ingress to the 3rd row, this will allow for some of the "Magic Seat" vertical storage height that the Honda Fit has, for example.
* Nice that they are allowing you to see your external paint colour choice at the same time as the interior seat colour choice. If I recall correctly, the Model S Design Studio does not allow for this. (nice job web guys)
* Ventilated and cooled seats - I would love these in the front of my Model S
Not sure they can hook up the cooling though - but ventilation, and the new shape which I now dub "3rd Gen Seats" - look
very comfortable. These may be the retrofittable front seats I purchase, if they become available.
* no cup holders for the middle row seats? Doesn't make sense. I looked in the opened falcon wing doors photo... saw nothing there.
* I think there will be a different, "basic" middle row seat option. These are the "Captain's" chairs if you will. Perhaps the basic seats will fold differently.
* You can't choose cloth for the Signature seats? Not everyone wants animal skin.
* I saw the overhead pic with two-colour seats... nice. Will make for lots of variety.
