Trunk comparison: Mercedes Benz GLB vs Nissan Rogue Sport

Key Differences (Summary)

The Mercedes‑Benz GLB offers 4.7 in more cargo length with the seats folded down and 3.1 in more cargo length with the first row upright than the Nissan Qashqai. The trunk opening of the GLB is 3.1 in (10%) higher.

Particularly notable is the depth of the trunk (distance from loading edge → trunk floor): the GLB is 2.4 in, or +100%, larger here than the Qashqai — this difference is especially significant.

The loading edge of the Qashqai, on the other hand, is 2 in higher above the ground, the trunk opening of the Qashqai is 2.4 in wider, and the narrowest width in the GLB is only 0.4 in larger.

Impact on Usability

The greater cargo length in the GLB allows for better transport of longer items (e.g., furniture boards, skis). The 3.1 in higher opening makes loading tall items easier.

Most important is the significantly greater depth: the 2.4 in (100%) greater distance from loading edge to trunk floor in the GLB increases the usable interior volume behind the loading edge and allows for deeper sinking of cargo — useful for tall or stacked loads.

At the same time, this creates a larger "step effect" when sliding heavy items in, which can make lifting over the edge somewhat more challenging.

The Qashqai scores with a slightly wider opening (+2.4 in), which facilitates loading very wide items. However, this is offset by its loading edge being 2 in higher, making lifting heavy loads more strenuous and longer items less suitable due to smaller interior length and depth.

Conclusion

For transport purposes where volume, length, and especially a deeper cargo floor matter, the GLB is more practical — particularly because of the significantly greater depth (100% difference).

If primarily very wide items need to fit through the rear opening, the Qashqai can offer advantages due to the wider opening, though with drawbacks from the higher loading edge and smaller interior dimensions.
