Trunk comparison: Mercedes Benz GLB vs VW Tiguan

Key Differences (>10%)

In a direct comparison, two clear advantages of the Mercedes-Benz GLB stand out: The height of the trunk opening is 5.5 in (19%) larger in the GLB than in the VW Tiguan, and the depth of the trunk (distance from loading edge → trunk floor) is 4.3 in (1100%) greater in the GLB.

Impact on Usability

The higher trunk opening of the GLB significantly eases loading of tall or bulky items: boxes, bicycles with the front wheel removed, plants, or furniture can be pushed in standing upright or with less tilting through the opening.

For users who frequently transport tall cargo, this reduces effort and the risk of hitting the roof or the opening.

The significantly greater trunk depth (greater vertical/sunken depth) means more usable interior space downward: higher stacking heights, more room for items stacked underneath and behind each other, and overall a larger capacity for irregularly shaped cargo.

At the same time, a deeper loading floor has practical consequences: items stored close to the floor are further from the opening edge and thus harder to reach; loading and unloading heavy loads can be more strenuous because more depth work or lifting/reaching combinations are required.

Smaller deviations (under 10%) — such as the slightly greater trunk length with folded seats (+3%) or with the first row upright (+8%), the 0.8 in higher loading edge of the Tiguan, or the slightly larger opening width of the Tiguan (+3%) — only minimally affect everyday usability.

In summary: Those who regularly transport tall or bulky items noticeably benefit from the GLB. Those who mainly need flat, wide, or easily accessible cargo will notice only minor differences between the models.
