Trunk comparison: BMW X2 vs Durchschnitt Wagon

Key Differences and Implications for Usability
The most noticeable difference: The average wagon has a significantly higher trunk opening (+5.1 in / +20 %) than the BMW X2. This makes it easier to load tall or bulky items and reduces the risk of bumping into the opening.
The BMW X2, on the other hand, offers a significantly greater trunk depth measured from the loading edge to the trunk floor (+2 in / +125 %) and a noticeably higher loading edge above the road (+6.7 in / +27 %).
Practically, this means the cargo space in the X2 sits deeper below the loading edge, which can provide more "stacking height" below the opening, but the higher loading edge makes lifting heavy items more strenuous and loading less comfortable.
Other differences are much smaller: The wagon has about +2.8 in longer space with folded seats and with the first row upright (4% and 8%, respectively), as well as approximately +4% at the narrowest point and about +5% more in opening width.
These advantages are practical but marginal: they allow for slightly longer or wider loads but only minimally affect daily usability.
Conclusion: Those who frequently load tall or bulky items and want easier loading benefit more from the wagon (higher opening).
Those who value a deeper interior compartment or more "recessed" cargo space and can live with a higher loading edge will find the BMW X2 to be a more compact but somewhat less practical solution for loading.
