Trunk comparison: Nissan Rogue Sport vs VW Polo

Key Differences
The Nissan Qashqai offers a significantly larger cargo area than the VW Polo in several aspects: with the seats folded down, the Qashqai's trunk is 10.6 in (+20%) longer, and when the front seats are upright, the length advantage is 8.3 in (+32%) in favor of the Qashqai.
Additionally, the Qashqai's trunk opening is 4.3 in higher (+16%) and the width of the trunk opening is 7.9 in wider (+22%) than that of the Polo.
The VW Polo, on the other hand, has a trunk depth between the loading edge and trunk floor that is 0.8 in greater (+33% relatively), which is noticeable percentage-wise but represents only a very small absolute difference.
Impact on Usability
These differences significantly affect practical use: The larger cargo space of the Qashqai (especially the longer dimensions with folded and upright seats) facilitates transporting long items such as furniture panels, skis, or longer boxes and increases flexibility with variable seat usage.
The higher and wider trunk opening of the Qashqai makes loading bulky or tall items easier — wider boxes and bulky luggage can be more easily positioned and loaded through.
The 0.8 in deeper interior of the Polo (measured from loading edge to trunk floor) can minimally favor stacking flatter items but is hardly noticeable in practice due to the small absolute difference.
The loading edge height (Qashqai is about 2.8 in higher above the ground here) can be relevant when lifting heavy loads: a higher loading edge means more lift when loading, which makes loading heavy boxes somewhat more strenuous.
Conclusion
For users who regularly transport longer or taller items or often work with bulky cargo, the Nissan Qashqai clearly has the advantage due to the longer cargo area as well as the higher and significantly wider opening.
The VW Polo remains compact and practical for everyday transport tasks; its marginally larger interior floor "depth" hardly has a decisive effect.
