X1 F48 boot/rear seat question

[CC1950]

I'm looking at possibly going for an X1 hybrid and I have a couple of questions about the boot/rear seat

Firstly, it seems that the Hybrid does not have the sliding rear seat so I need a bit more info about the boot layout

1) does someone have the measurement length of the boot floor from the rear seat to the inside of the rear door sill (i.e. the usable length)?
2) is the rear seat backrest adjustable for angle i.e. can it be set vertical to maximise the boot area when fitting a dog cage in?

I suppose that the floor width between the wheel arches would also be useful if possible.

I am assuming that these points would be the same whether the car was hybrid or not, just with the lack of seat travel on the hybrid, assuming that the seats only move forward when the option is there, the measurements from a normal car with the seats back, should be OK.

Thanks
