Trunk comparison: BMW X4 vs VW ID.3
Key Differences
The BMW X4 offers a longer cargo area: with the seats folded down, the trunk of the X4 is
longer, and with the front seat row upright, the advantage is
. The VW ID.3 has a significantly greater trunk depth (distance from loading edge to trunk floor): it is
above the X4's value. Smaller deviations under 10% are: the trunk opening of the ID.3 is 2 in (≈7%) higher, the loading edge of the BMW is 0.8 in (≈3%) higher above the ground, the narrowest interior width of the ID.3 is 0.4 in (≈1%) larger, and the width of the X4's trunk opening is 2.8 in (≈7%) larger.
What does this mean for usability?
- Length (advantage BMW X4): The X4 is better suited for long items (e.g., skis, boards, long boxes). The clear length advantage both with folded seats and with the front row upright means more usable depth in the cargo space for flexible loading and longer luggage. - Depth / Floor Seat (advantage VW ID.3): The significantly greater distance from loading edge to trunk floor in the ID.3 creates more vertical space behind the loading edge — beneficial for tall or stacked cargo and for items that need to be slid into a recess. However, this may mean that when pushing items in after overcoming the loading edge, a "lowering" into the recess is necessary. - Loading and unloading (minor differences): The BMW's loading edge is slightly higher (+0.8 in), which makes lifting minimally more difficult; the higher opening sill of the ID.3 (+2 in) offers a bit more headroom when loading. These differences are small and hardly affect everyday use. - Width (minor differences): Interior and opening widths differ by only a few centimeters, so lateral restrictions with normal luggage loading are barely noticeable. Conclusion: For frequent transport of long items and flexible use of the cargo space, the BMW X4 is the better choice; for more usable depth, better stacking, and higher storage space behind the loading edge, the VW ID.3 is better suited. Smaller differences in opening height, loading edge height, and width are hardly decisive in everyday life.
