Trunk comparison: BMW X2 vs VW ID.4

Key Differences

The VW ID.4 offers slightly more cargo space overall, with most differences being minor: with the seats folded down, the ID.4 is only +1.2 in (2%) longer, and with the first row upright, it is +0.4 in (1%) longer than the BMW X2. At the narrowest point, the ID.4 is only +0.4 in (1%) wider, and the width of the trunk opening in the ID.4 is +3.1 in (8%) greater than the X2. The loading edge of the BMW X2 sits +2.4 in (8%) higher above the road than the ID.4.

The ID.4 has a clear advantage in the height of the trunk opening: it is +5.5 in (21%) higher than the X2. Additionally, the depth of the trunk (loading edge to trunk floor) in the ID.4 is +0.4 in (11%) larger.

Impact on Usability

The significantly higher trunk opening in the ID.4 makes loading bulky or tall items (e.g., boxes, strollers, bicycle accessories) easier because more vertical space is available and inserting large parts is simpler.

The greater depth of the cargo area (by 11%) means more storage space vertically inside the trunk, which is especially relevant when stacking or transporting taller items.

The slightly wider opening (+3.1 in) and the minimally larger interior dimensions of the ID.4 further improve handling when loading and unloading, but these are less significant.

The higher load floor of the X2 (+2.4 in) makes lifting heavy cargo somewhat more strenuous—especially compared to the ID.4 with its lower loading edge.

In summary: For users who frequently transport bulky, tall, or stackable cargo, the VW ID.4 is more practical due to the significantly larger opening height and deeper loading area. Differences in overall length, interior width, and folded seats are minor and have little impact in everyday use.
