Trunk comparison: Audi Q5 vs BMW iX1

Key Differences and Their Impact

The most noticeable difference lies in the depth of the trunk: the Audi Q5 has a depth that is 2.4 in greater, indicated as +300%. This significantly greater interior height between the loading edge and the trunk floor means more usable volume in the lower area, better securing of small items, and more space for stackable or irregularly shaped cargo. However, the loading edge of the Q5 is 0.8 in higher above the road (+3%), which requires slightly more effort when lifting heavy items.

Other, smaller differences concern length and width: with the seats folded down, the Q5 is 1.6 in longer (+2%), with the first row upright 2 in longer (+6%), the narrowest width is 1.2 in greater (+3%) on the Q5, and the width of the trunk opening is 1.6 in wider (+4%).

The height of the trunk opening is 2.8 in higher (+10%) on the Q5. Together, these dimensions mean that the Q5 offers somewhat more cargo space for longer items and can accommodate bulky cargo more easily due to the slightly larger opening and width; however, the advantage here is moderate.

In practice, this means: For everyday use with shopping or travel cargo, the Q5 offers noticeably more volume and more stable storage of small to medium-sized items, mainly due to the deeper trunk well.

For loading very heavy parts, the slightly higher loading edge of the Q5 is a minor disadvantage compared to the iX1, while the iX1 allows somewhat more comfortable lifting thanks to its lower loading edge.

Longer or slightly wider items tend to fit more easily in the Q5, but the overall advantage is moderate to small — with the exception of the significantly greater depth, which provides the greatest practical benefit.
