Trunk comparison: Mercedes Benz GLB vs VW Golf Wagon

Key Differences

The VW Golf Wagon offers slightly more length with the rear seats folded down, and with the front seats upright the advantage is clearer: the Golf Wagon has +5.5 in (15%) more cargo length than the Mercedes-Benz GLB.

On the other hand, the GLB scores in vertical space: the trunk opening is +3.9 in (13%) higher than that of the Golf Wagon. Additionally, the loading edge of the GLB sits +4.3 in (18%) higher above the ground than the Golf Wagon.

Impact on Usability

The greater cargo length of the Golf Wagon with the front seats upright makes it more practical for longer items without folding down the front seats (e.g., slats, long boxes, skis), so folding seats down can be avoided more often. With all seats folded down, the advantage shrinks to +3.9 in (6%) and is rather small.

The higher trunk opening of the GLB allows easier loading of taller, upright items — standing boxes, plants, or bulky crates can be accommodated more easily.

However, the higher loading edge of the GLB means lifting heavy or awkward loads to a greater height, making loading and unloading more strenuous and increasing the risk of twisting or injury.

The Golf Wagon has the advantage here with its lower loading edge for frequent transport of heavy items or frequent loading and unloading.

Other, smaller differences: the depth (loading edge to ground) of the GLB is +0.4 in (9%) greater, the narrowest width of the trunk is +1.6 in (4%) wider in the GLB, and the width of the opening is +2.4 in (6%) wider — these advantages exist but fall below the 10% threshold and have a rather minor impact in everyday use.

Conclusion

In short: For longer, flat cargo with rear seats left upright, the VW Golf Wagon is more practical. For loading tall items, the Mercedes-Benz GLB offers clear advantages but pays for this with a higher loading edge that makes lifting heavy loads more difficult.
