Trunk comparison: Mercedes Benz GLB vs Volvo V90
Key Differences
The Volvo V90 offers overall more cargo length: when all seats are folded down, it is 6.7 in longer (+10%) than the GLB, and with the first row upright, the V90's advantage is even
. In terms of trunk opening and interior geometry, the Mercedes GLB leads: the height of the trunk opening is
greater, the depth of the trunk (loading edge to trunk floor) is
greater in the GLB, and the loading edge is
higher above the road. The narrowest trunk width is the same for both models, while the width of the trunk opening is 3.1 in (8%) larger on the V90.
Impact on Usability
The longer cargo area of the Volvo V90 (especially the
greater length with the first row upright) makes it better suited for long, flat items like boards, skis, or long boxes — in situations where length is more important than height, the V90 offers a clear advantage. The slightly larger opening width of the V90 (3.1 in) makes it easier to slide in wide items, while the same narrowest cross-section means tight passages in the cargo area are equally relevant for both. The Mercedes GLB, on the other hand, is advantageous for tall or bulky loads: the significantly greater opening height (
) allows loading tall items without angled lifting. The greater depth between loading edge and trunk floor (
) creates more usable interior space below the loading edge, suitable for stackable or taller cargo and provides additional storage space. However, the higher loading edge of the GLB (
) means a higher lift or maneuver height when loading and unloading; heavy items must be lifted higher, which can make handling more difficult. In short: for long, flat goods and easy sliding in and out, the Volvo V90 is the better choice; for tall, bulky cargo and more interior height/depth, the Mercedes GLB is more suitable — but with heavy goods, the higher loading edge of the GLB can complicate handling.
