Trunk comparison: Nissan Rogue Sport vs Opel Grandland

Key Differences
The Opel Grandland offers a trunk that is 1.6 in longer (+2%) with the seats folded down and 0.8 in more (+2%) with the first row upright compared to the Nissan Qashqai. The height of the trunk opening is 0.4 in higher (+1%) on the Grandland, as is the loading edge (+1%).
The width at the narrowest point is 1.2 in greater (+3%) on the Qashqai, and the width of the trunk opening is 1.6 in greater (+4%) on the Qashqai. Notably, the trunk depth (loading edge to trunk floor) is 3.9 in greater at the front on the Grandland, which corresponds to +167% compared to the Qashqai.
Impact on Usability
The clearest practical advantage lies with the Grandland due to its significantly greater trunk depth: this extra depth creates noticeably more usable volume and allows for the secure placement of taller or better stackable items.
For groceries, suitcases, or bulky, tall cargo, the Grandland is more advantageous in everyday use.
In contrast, the Qashqai, with its slightly greater width at the narrowest point and a wider opening, makes loading wider items or bulky boxes easier; however, these advantages are moderate (3–4%) and only noticeably affect very wide cargo.
The slightly higher loading edge and opening height on the Grandland (+0.4 in) practically mean only a minimal increase in maneuvering or lifting effort when loading. The length differences (2–1.6 in) are so small that they generally do not cause noticeable limitations for everyday use.
Conclusion: Those who need more usable volume and space for taller/stackable loads clearly benefit from the Opel Grandland. Those who more often need to push very wide items through the opening have a slight advantage with the Nissan Qashqai; all other differences are practically marginal.
