Trunk comparison: BMW 5 Series Touring vs BMW iX1

Key Differences

The BMW 5 Series Touring offers significantly more cargo length: with the seats folded down, the trunk is 11 in (≈17%) longer, and with the first row of seats upright, it is 7.5 in (≈21%) longer than in the BMW iX1. Additionally, the depth of the trunk (distance from loading edge → trunk floor) of the iX1 is 0.8 in (100%) greater than that of the 5 Series Touring.

Impact on Usability

More cargo length in the 5 Series Touring means a clear advantage for long items (e.g., furniture parts, long sports equipment, building materials) and for an overall more flexible cargo volume with folded seats.

Those who regularly transport long or bulky loads benefit practically and comfortably from the additional 17–21% length.

The greater depth in the iX1 creates a bit more volume below the loading edge and can better "hide" smaller items or secure them in the lower area. This is practical for crates and shopping bags.

However, a deeper trunk floor can make loading large, heavy items somewhat less comfortable because they must be lifted deeper or inserted further in.

Other differences are smaller than 10%: The trunk opening of the iX1 is 0.8 in higher (+3%), the loading edge of the iX1 is 2.4 in higher above the road (+9%), the narrowest trunk width is 2.8 in wider (+7%) in the 5 Series Touring, and the opening width of the iX1 is 1.2 in larger (+3%).

These differences only moderately affect everyday usability: the higher opening of the iX1 slightly eases loading tall items, the higher loading edge makes lifting heavy loads a bit more strenuous, and the greater interior width of the 5 Series Touring helps when stowing wide objects.
