Trunk comparison: Audi Q5 vs BMW X4

Key Differences

In comparison, the BMW X4 offers a slightly longer cargo length: with the seats folded down, the trunk of the X4 is 2.4 in (4%) longer, and with the first row of seats upright, it is 2.8 in (7%) longer. The trunk depth (loading edge to trunk floor) is the same in both models. However, the loading edge of the X4 sits 2 in (7%) higher above the road. The width at the narrowest point is 1.2 in (3%) greater in the Audi Q5, and the width of the trunk opening in the Q5 is 3.9 in (10%) larger. The height of the trunk opening is significantly different: the Audi Q5 has an opening that is 3.5 in (13%) higher than the BMW X4 — this difference is the most pronounced and noticeably impactful.

Impact on Usability

The 13% higher trunk opening of the Audi Q5 makes loading noticeably easier: tall or bulky items can be inserted more easily at an angle, and packing bulky boxes, plants, or furniture requires less effort and maneuvering space. Loading suitcases or shopping bags is also more comfortable due to the larger opening. The BMW X4 wins in cargo length — longer items (e.g., skis, slats, long boxes) fit somewhat better in the X4, especially when the seats are folded down. However, the lower opening height and somewhat narrower opening (Q5 +3.9 in) limit the practical loading of long or wide items: although the X4 measures deeper in the cargo area, these items often need to be tilted or turned, which complicates handling. The higher loading edge of the X4 (+2 in) makes lifting heavy items into the cargo area more strenuous compared to the Q5. For everyday use (weekly groceries, travel suitcases, strollers), the Audi Q5 is generally more practical due to the larger opening and wider entry. For users who regularly transport long, flat items, the BMW X4 can offer advantages due to the slightly greater interior length — provided these items can be maneuvered through the lower opening and higher loading edge.
