Trunk comparison: Nissan Rogue Sport vs VW ID.3

Key Differences (>10%)
Two noticeable differences stand out in the comparison: The depth of the trunk (distance from loading edge to trunk floor) is 3.9 in (+167%) greater in the VW ID.3 than in the Nissan Qashqai, and the width of the trunk opening is 6.3 in (+17%) greater in the Nissan Qashqai than in the VW ID.3. These two values exceed the 10% threshold and are thus the most relevant deviations between the models.
Impact on Usability
The greater trunk depth of the VW ID.3 practically means more usable vertical or interior depth: tall or bulky items can be loaded deeper and thus often more space-efficiently stacked.
However, the deeper loading floor creates a greater height difference from the loading edge to the bottom of the cargo area, which can make lifting heavy items in and out somewhat less comfortable.
The significantly wider trunk opening of the Qashqai greatly facilitates loading and unloading wide or bulky items: wide furniture pieces, boxes, or rolling containers can be maneuvered more easily without needing to tilt them.
Combined with the overall slightly longer interior length (with seats folded down), the Qashqai is generally more practical for wide and flat cargo.
Other, smaller differences: The Qashqai offers a somewhat longer loading length with folded seats (+4.7 in / 8%) and with the first row upright (+3.1 in / 10%), the height of the trunk opening is +2 in (7%) greater in the Qashqai, the narrowest interior width is only slightly (+1.2 in / 3%) greater, and the loading edge height is the same for both models.
These values influence everyday usability less noticeably than the two features mentioned above.
Conclusion
Those who frequently transport wide or bulky items benefit from the larger opening cross-section of the Nissan Qashqai.
Those who need more deep interior height for tall/bulky cargo or better stacking volume have an advantage with the VW ID.3. For heavy items, the identical loading edge height of both vehicles can help balance out, while the deeper loading floor of the ID.3 makes lifting somewhat more demanding.
