One point of interest...if Tesla did change the pedestal location, I can't see Tesla having two different variations of the pedestals (one for 6 seater and one for 7 seater). I would expect Tesla to cancel the 7-seat option so that they still only have 1 pedestal variation.vandacca: OK, thank you. I guess the photos are just doing tricks in my eyes on depth...
Regarding placement, I guess one more option would be that six-seater has different seat placement than the seven-seater, slightly closer to the middle. This would probably require some adjustment to the floor structure (like two different attachment points for outer seats on six/seven seaters) but implementing such a change while doing the five-seater certainly could be possible.
That said, it does not look that different - location-wise - to me in the photos.
