Trunk comparison: Hyundai IONIQ vs Mercedes Benz GLB

Key Differences and Impact on Usability

The Mercedes-Benz GLB offers a significantly different trunk geometry compared to the Hyundai IONIQ. The most noticeable differences are two: the height of the trunk opening is +8.7 in (33%) larger on the GLB, and the width of the trunk opening is +4.7 in (13%) larger.

These two values mean that the GLB can much more easily accommodate large, tall, or bulky items – for example, furniture parts, strollers with a high setup height, or bulky sports equipment. The larger opening reduces tilting and maneuvering when loading and increases pass-through convenience.

Other measured differences are moderate or minor: with the seats folded down, the GLB is about +5.5 in (9%) longer, with the first row of seats upright +1.6 in (4%).

The depth of the trunk (loading edge to floor) is the same, the narrowest trunk width is +2 in (5%) larger on the GLB, and the loading edge of the IONIQ is +0.8 in (3%) higher than on the GLB.

These differences only slightly affect usability: the somewhat greater length of the GLB can accommodate longer items but is not a major advantage; the slightly lower loading edge of the GLB makes lifting heavy loads minimally easier.

Conclusion: Those who frequently need to store tall or wide and bulky cargo will noticeably benefit from the GLB due to the significantly larger opening height and width. For mostly normal luggage and occasional transports, the differences are rather minor, and the IONIQ remains sufficient in practice.
