Trunk comparison: BMW X4 vs Durchschnitt Compact SUV

Key Differences

The BMW X4 offers a significantly longer cargo floor: With the seats folded down, the trunk of the BMW X4 is 9.1 in (15%) longer, and with the first row upright even 9.8 in (32%) longer than the average compact SUV.

In contrast, the average compact SUV has a trunk opening that is 3.5 in (13%) higher and a significantly greater depth (loading edge to trunk floor) by 2.4 in (75%) compared to the BMW X4.

Implications for Usability

The longer cargo floor of the BMW X4 makes it more practical for long or flat loads — such as skis, long furniture parts, or bulky items that require lengthwise space. Especially with the first row upright, the X4 offers noticeably more usable length.

The greater opening height and the deeper trunk recess of the average SUV are more suited for loading tall items or for a larger usable volume in the lower part of the trunk.

However, the deeper floor position (greater depth) also means that items slide further down after overcoming the loading edge — this can be less convenient when loading and unloading heavy or awkward loads.

In practice, this means: If you frequently transport long items or value a continuous, longer cargo floor, the BMW X4 is more advantageous for everyday use.

If, on the other hand, you often load tall or bulky cargo and prefer a higher opening, an average compact SUV offers benefits but accepts a deeper cargo floor that can make handling heavy items somewhat more difficult.
