Trunk comparison: Mercedes Benz GLB vs Durchschnitt SUV

Key Differences (Brief Summary)

The Mercedes‑Benz GLB offers noticeable advantages over the average SUV in several dimensions. With the front seats upright, the GLB's trunk is +3.9 in (12%) longer. The height of the trunk opening is +4.3 in (14%) larger, and the depth from the loading edge to the trunk floor is +2.8 in (140%) deeper/larger.

Smaller or negligible differences: with the seats fully folded down, the GLB is +6.3 in (10%) longer (exactly 10% — not highlighted as >10%), the narrowest width is only +0.8 in (2%) larger, and the width of the opening is the same.

The loading edge of the average SUV is also slightly higher (+1.2 in / 4%) above the ground than that of the GLB.

What Impact Do These Differences Have on Usability?

The longer usable length with the front seats upright (+3.9 in / 12%) makes the GLB more practical for longer items transported without folding down seats — such as skis, building materials, or furniture parts that need to be stored behind the first row.

The greater height of the opening (+4.3 in / 14%) makes loading and unloading taller or bulky items easier because there is more clearance.

The significantly greater depth from the loading edge to the trunk floor (+2.8 in / 140%) creates more usable volume below the loading edge. Practically, this means bulky or tall items sit deeper in the cargo area, items can be stacked better, and the floor space is used more effectively.

Combined with the slightly lower loading edge of the GLB (1.2 in lower than average), the lifting or loading height is reduced — which is advantageous when loading heavy items.

In summary: The GLB is better suited for users who frequently transport tall or long bulky cargo and want to minimize folding seats or lifting.

Those who only occasionally transport small items or rely on maximum opening width will notice little difference — the opening width is the same, and the narrowest point differs only minimally.
