Trunk comparison: Mercedes Benz GLB vs VW Tiguan Allspace

Key Differences (more than 10%)

Several measurements clearly favor one of the two models.

Four differences stand out: The VW Tiguan Allspace offers a longer loading floor in one seating configuration (+6.7 in, +18%), while the Mercedes-Benz GLB is clearly ahead in free cargo capacity: with upright seating, the GLB has a trunk that is +18.9 in (+102%) larger, the height of the trunk opening is +6.3 in (+22%) greater on the GLB, and the height difference between the loading edge and trunk floor on the GLB is +4.7 in (+1100%).

Impact on Usability

The practical consequence of these differences can be summarized as follows: The Tiguan Allspace is advantageous when it comes to loading particularly long items in certain seating configurations — it offers more usable length in this situation (+6.7 in / 18%).

This makes it more suitable for transport tasks where length matters (e.g., long pipes, slats, skis), provided the seating arrangement matches the measured configuration.

The Mercedes-Benz GLB clearly wins in cargo height and interior volume in upright or everyday situations: The significantly greater trunk length with upright seats (+18.9 in / 102%) means more usable loading floor with full passenger seating; the higher opening (+6.3 in / 22%) makes it easier to load tall items and reduces head or angled posture when loading; the significantly greater height between the loading edge and trunk floor (+4.7 in / 1100%) creates either a deeper loading well or more vertical space under the loading edge, which facilitates storing bulky or tall items and prevents them from protruding over the loading edge.

In short: For length-specific transports in certain seating configurations, the Tiguan Allspace scores points. For everyday use with frequent, bulky, or tall loads as well as full seating, the GLB is ergonomically and practically superior.
