rear seatback

Inside, the X1 has space for five, with the rear seatback split 40/20/40 to expand cargo space when needed and still retain passenger space. The angle of the rear seatback is also adjustable, and thanks to that the cargo space can be varied from 12.7 to 17.0 cubic feet. Otherwise, all of the seatback sections fold forward to a flat cargo floor, and there's enough continuous length beside the seat to fit two snowboards or four pairs of skis, according to BMW
