Trunk comparison: Mercedes Benz GLB vs Skoda Elroq

Key Differences

In comparison, the Mercedes‑Benz GLB offers significant advantages in several usability-relevant dimensions.

The trunk is 5.9 in (19%) longer with the front seats upright than in the Škoda Elroq, the height of the trunk opening is +4.7 in (16%) compared to the Elroq, and the depth between the loading edge and trunk floor is 4.3 in (1100%) greater.

Smaller advantages of the GLB also include a trunk that is 3.9 in (6%) longer with the seats folded down, a loading edge that is 1.2 in (4%) higher, a narrowest trunk width that is 2 in (5%) larger, and a trunk opening that is 1.2 in (3%) wider.

Impact on Usability

The notable differences have the following practical effects: The 19% longer cargo floor with the front seats upright makes the GLB significantly more practical when passengers remain seated — longer items (e.g., skis, furniture parts) fit more easily without folding down the seats.

The 16% higher opening facilitates loading tall or bulky items because more vertical space is available. The very large difference in depth between the loading edge and trunk floor creates additional usable space immediately behind the loading edge (better stackability, more room for bulky items).

The smaller differences only slightly affect everyday usability: The slightly higher loading edge of the GLB (+1.2 in) increases the effort required to lift heavy loads somewhat but can be compensated by the larger interior space.

More width at the narrowest point and at the opening makes maneuvering bulky items easier but are only marginal advantages.

Conclusion: Those who frequently transport long or tall/bulky cargo or need to load with passengers seated will noticeably benefit from the GLB. For mostly smaller shopping trips or occasional transports, the differences are less relevant.
