There's a lot of room. X3 has 63.3 cu.ft. with seats down. F31 has 54.3. X1 has 47.7. So, it's right in the middle - on paper. In reality, X3 wins only by having more height, its floor space is virtually the same if not less (the rear overhang on the X3 is actually shorter than on F31). So, unless you really pack the car to the ceiling, an F31 would be at least as useable in hauling stuff as an X3. All that with 300lbs less weight, 20% fuel savings, and one billion times more fun to drive.
X vehicles are popular because most people are afraid of driving, not because they have better utility.
