Trunk comparison: BMW X2 vs VW T-Roc

Key Differences
In terms of cargo space, the BMW X2 clearly offers longer loading surfaces lengthwise: with the seats folded down, the X2 is +7.1 in (12%) longer, and with the front seats upright even +5.9 in (19%) longer than the VW T-Roc.
Conversely, the VW T-Roc provides significantly more favorable dimensions for bulky or awkward cargo: the height of the trunk opening is +7.9 in (30%) higher, the depth (loading edge → trunk floor) is +5.1 in (144%) greater, and the width of the opening is +5.5 in (14%) wider than in the X2. Smaller differences with little impact include the X2's loading edge being 1.2 in (4%) higher and the T-Roc's narrowest width being only 0.4 in (1%) larger.
Impact on Usability
The longer loading surface of the BMW X2 makes it better suited for long, flat items: such as skis, long furniture parts, planks, or boxes that need to be laid lengthwise.
Even with the rear seats upright, the X2 offers noticeably more length, which is practical for transporting longer individual items in everyday use.
The VW T-Roc, on the other hand, is more advantageous when it comes to loading and unloading bulky, voluminous, or tall cargo.
The significantly higher opening height and larger opening width make it easier to maneuver wide furniture pieces, bulky boxes, or strollers inside; the greater depth between the loading edge and trunk floor provides more interior volume in depth and more space for stacking.
This is also beneficial when loading awkward items or large moving boxes.
Practical example: For longer, slender items (boards, skis, long boxes), the X2 is the more practical choice. For wide, tall, or difficult-to-maneuver items (furniture parts, large boxes, bulky equipment), the T-Roc is better suited due to the larger opening and depth.
Note: The slightly higher loading edge of the X2 (+1.2 in) can make lifting heavy items a bit more difficult but is insignificant compared to the main differences mentioned. The minimal width difference inside the trunk plays hardly any role in everyday use.
