Trunk comparison: BMW X5 vs Ford Escape

Key Differences
Between the BMW X5 and Ford Kuga, it is generally evident that the X5 is somewhat more generous in several dimensions: with the seats folded down, the cargo space is +5.1 in (≈8%) longer, with the first row of seats upright +2.4 in (≈6%) longer, and the narrowest width in the trunk is +2.4 in (≈6%) larger.
The trunk opening height of the X5 is +1.6 in (≈5%) greater, the opening width +1.2 in (≈3%) wider, and the depth (loading edge to trunk floor) is the same.
The loading edge height is particularly noteworthy: the loading edge of the BMW X5 is +3.5 in (≈13%) higher above the ground than that of the Ford Kuga — this is the only value with more than a 10% difference.
What are the practical implications?
The larger dimensions of the X5 mean overall more space for longer and slightly wider items: folded down, the +5.1 in additional length mainly benefits long cargo such as furniture moldings or skis. The slightly larger opening height and width make loading tall or bulky items somewhat easier.
The more significant practical consequence comes from the higher loading edge of the X5: due to the +3.5 in higher loading edge, lifting heavy or bulky loads into the trunk is more strenuous.
This negatively affects regular transport of heavy boxes, bulky items, older individuals, or when no aids (ramp, lifting assistance) are available. Conversely, the Kuga with its lower loading edge is easier to load.
Since the cargo depths are the same, the X5 and Kuga do not differ in usable interior length from the loading floor to the loading edge; the advantages of the X5 lie more in length and slightly more width, while the Kuga scores in comfortable loading and unloading.
Conclusion
The BMW X5 offers overall slightly more volume and better dimensions for longer or somewhat wider cargo. The Ford Kuga, on the other hand, is easier to load due to the significantly lower loading edge.
If the focus is on frequent lifting of heavy loads or easy cargo handling, the Kuga is more advantageous; if more storage space for long/bulky items is needed, the X5 is better suited.
