While I, too, hope the X provides a better rear seat experience, I am disappointed that the S rear seat geometry is so compromised. Sitting in the back, I find that I cannot get my feet under the front seats, regardless of their adjustment, meaning my knees are bent more than in other, lesser cars. In addition, in this position, the distance between the back of my thighs and the seat is unacceptable (many inches), meaning my weight is all on the bum and none on the thighs. I am 5'11", so I would not expect to have this problem in an otherwise comfortable cabin.
