Trunk comparison: BMW X2 vs Durchschnitt Subcompact

Key Differences
The BMW X2 offers significantly more cargo length: with the seats folded down, the trunk is 15 in (≈30%) longer, and with the front seat row upright, 11.8 in (≈48%) longer than the average subcompact. This practically means more usable length for long items like skis, furniture boards, or long boxes.
The average subcompact, on the other hand, leads in vertical capacity: the height of the trunk opening is 5.9 in (≈23%) greater and the depth (distance from loading edge to trunk floor) is 3.9 in (≈111%) greater than in the BMW X2. This makes loading very tall or bulky items easier and provides more space for stacking vertically.
Impact on Usability
Due to the greater cargo length, the BMW X2 is clearly advantageous when frequently transporting long items or when a lot of cargo space in lengthwise direction is needed with folded seats (e.g., lawn mowers, long furniture parts, sports equipment). It is more practical for everyday luggage and long transports.
The average subcompact is better suited when tall or bulky items often need to be loaded (e.g., tall boxes, plants, bulky crates), because the larger opening height and interior depth make loading and stacking easier. Additionally, the larger volume under the opening can be advantageous when vertical capacity matters.
Other minor differences: The loading edge of the BMW X2 is 2.8 in (≈10%) higher above the road, which makes lifting heavy loads somewhat more difficult, and the width at the narrowest point (+0.8 in) as well as the opening width (+3.1 in) of the X2 are only slightly larger and have little practical effect.
