Trunk comparison: Audi Q7 vs Mercedes Benz GLB

Key Differences (highlighted: >10%)

The following differences stand out in the comparison: The Audi Q7 offers a longer cargo length both with the seats folded down (+10.2 in / +15%) and with the first row upright (+9.4 in / +25%).

The width of the trunk opening of the Audi Q7 is significantly larger (+5.9 in / +14%). The Mercedes-Benz GLB has a higher trunk opening (+5.1 in / +17%) and a significantly greater depth between the loading edge and the trunk floor (+4.7 in / +1100%).

Impact on Usability

More cargo length in the Q7 practically means: long items (skis, long furniture parts, shutters, ladders) are easier to transport — both with folded seats and with normal seating. For moving or transporting bulky elongated cargo, the Q7 is clearly advantageous.

The greater opening width of the Q7 makes loading wide or awkward items (boxes, strollers, bulky cartons) easier without strong squeezing or tilting.

The GLB scores with height and "depth": The higher trunk opening makes it easier to load tall items and reduces bending when loading (e.g., tall boxes, plants, suitcases).

The greater distance between the loading edge and trunk floor means more vertical interior space below the opening (more usable height in the lower area), but it can also mean that heavier items need to be lowered further when loading — making handling heavy loads somewhat more cumbersome.

Conclusion: For transport tasks with long or wide items, the Audi Q7 is better suited. For loading tall or bulky but not particularly long cargo, the GLB offers advantages due to the higher opening and deeper cargo floor.
