Trunk comparison: Fiat Panda vs Mercedes Benz GLB

Key Differences

The clearest advantage of the Mercedes‑GLB lies in the loading length: with the seats folded down, the GLB is 26 in (59%) longer, and with the first row of seats upright, even 16.1 in (76%) longer than the Fiat Panda.

Another significant difference concerns the depth between the loading edge and the trunk floor: the Fiat Panda has +2.4 in (50%) more here compared to the GLB.

The other dimensions differ only slightly: width at the narrowest point +1.6 in (4%) in favor of the GLB, width of the trunk opening +2.4 in (6%) for the GLB, and the loading edge height above the road is +1.2 in (4%) higher on the GLB. The height of the trunk opening is the same for both models.

Impact on Usability

The large length difference makes the GLB clearly better suited for transporting long items (e.g., slats, long boxes, skis with seats folded down) and for larger, continuous cargo areas when moving or transporting furniture parts.

Those who regularly transport bulky, longer cargo will benefit significantly from the GLB.

The 2.4 in (50%) difference in depth between the loading edge and trunk floor affects loading and unloading: a greater distance changes the lifting and pushing motion when stowing heavy or tall items.

This can either increase the sense of space in the trunk or make handling when lifting/setting down more difficult—depending on the design and arrangement of the interior walls. Since the difference is relatively large, it noticeably affects everyday practicality when loading.

The smaller differences in opening width and trunk cross-section (each under 10%) are less decisive in daily use: they slightly ease loading wide but not overly bulky parts in favor of the GLB.

The small, 1.2 in higher loading edge of the GLB is practically negligible—it makes lifting minimally more strenuous but remains a minor factor compared to the length and depth differences.

Conclusion: For regular transport of long or large cargo, the Mercedes‑GLB is the better choice.

If handling during loading (lifting heights, compact, more vertical cargo) or city size is more important, the Fiat Panda can be more advantageous in everyday use—the largest, decisive differences, however, concern loading length in favor of the GLB and depth between loading edge and trunk floor in favor of the Panda.
