Trunk comparison: BMW X2 vs VW ID.3

Key Differences
Three relevant advantages stand out in the comparison: The BMW X2 offers a significantly longer cargo space with the rear seats upright — +5.5 in (18%) — compared to the VW ID.3. On the other hand, the trunk opening of the ID.3 is higher than that of the X2 — +3.5 in (14%) — and the measured depth of the ID.3 (loading edge to trunk floor) is +2.8 in (78%) greater.
Smaller differences (e.g., +5.1 in/8% with seats folded down in favor of the X2, +1.2 in loading edge height on the X2, width differences of 1–1.2 in) exist but remain below the highlight threshold.
Impact on Usability
These measurements lead to clear practical consequences: Due to the greater loading length with the rear seats upright, the BMW X2 is better suited for long items that need to be transported without folding down the rear seats (e.g., slatted bed bases, long packages, or skis).
The ID.3, on the other hand, scores with bulky or tall loads: the higher trunk opening makes loading and unloading tall items easier and prevents bumping against the upper edge, while the greater depth (loading edge → floor) creates more usable vertical interior space and allows better stacking or accommodation of taller luggage.
Practically, this means: For users who frequently transport long, flat loads with full rear seats, the X2 is more advantageous in everyday use.
For those who often load bulky or tall objects or value easier sliding in of heavy items (lower edge on the ID.3), the ID.3 is the more practical choice. Width differences are minimal and hardly affect usability in most everyday scenarios.
