Trunk comparison: Mercedes Benz GLB vs Volvo XC40

Key Differences and Impact on Usability

The Mercedes-Benz GLB stands out with two significantly larger cargo dimensions: the height of the trunk opening is 5.9 in (+21%) higher, and the depth of the trunk (loading edge to trunk floor) is 4.7 in (+1100%) greater than in the Volvo XC40. These two differences together noticeably improve everyday usability: the higher opening makes it easier to load tall or bulky items (e.g., strollers, cabinets, tall suitcases) because you have to avoid bumping less lengthwise, and the greater depth creates more usable cargo space behind the loading edge, allowing longer items to lie flatter and be better stored or stacked.

Other deviations are significantly smaller: with the seats folded down, the GLB is 3.5 in (+5%) longer, with the first row upright 1.6 in (+4%) longer, the narrowest trunk width is 1.6 in (+4%) larger in the GLB, and the loading edge of the XC40 sits 1.2 in (+4%) higher above the road.

The width of the trunk opening is the same in both models. These smaller differences only slightly affect usability: for normal shopping, family, or travel trios, both models are largely equally practical, while the GLB clearly has the advantage when frequently transporting tall or longer items.
