Trunk comparison: BMW X1 vs Nissan Rogue Sport

Key Differences
Most differences between the BMW X1 and Nissan Qashqai are minor. However, two values stand out: the height of the trunk opening on the Nissan Qashqai is 3.1 in (≈11%) larger than on the BMW X1, and the depth of the trunk (loading edge to trunk floor) is 1.2 in (100%) greater on the Qashqai.
Other differences are significantly smaller: with the rear seats fully folded down, the Qashqai offers only +0.4 in (1%) more length, the BMW X1 has +1.2 in (3%) more cargo space with the front seats upright, the loading edge of the Qashqai is +2.4 in (8%) higher above the ground, the narrowest width is +1.2 in (3%) larger on the Qashqai, and the opening width is +2 in (5%).
Impact on Usability
The greater opening height of the Qashqai makes loading tall items easier: bulky boxes, suitcases, or furniture pieces fit more easily through the opening without needing to be tilted.
The significantly greater depth (loading edge → trunk floor) increases usable volume near the floor and allows items to sit deeper and thus often more securely; this is an advantage when transporting bulky luggage or storing crates.
At the same time, a deeper loading floor can make lifting heavy loads somewhat less convenient because you have to reach further down.
Small length and width differences have little noticeable effect in everyday use: the BMW X1 offers slightly more length with the rear seat upright (advantageous for very long, flat items), while the Qashqai has a bit more room at the narrowest points and in the opening width.
The slightly higher loading edge of the Qashqai (not >10%) can make lifting heavy loads a bit more difficult, whereas the lower loading edge on the BMW makes loading more ergonomic.
Conclusion: Those who frequently transport tall or low-lying bulky cargo practically benefit from the Nissan Qashqai (highlighted: larger opening height and greater depth). For easier handling of heavy items and slightly more length with the rear seat upright, the BMW X1 is marginally advantageous.
