Trunk comparison: BMW iX1 vs Mercedes Benz GLC

Key Differences

The Mercedes‑Benz GLC offers a longer trunk with the rear seats folded down (+5.1 in / 8%) and also slightly more length with the rear seats upright (+1.2 in / 3%) compared to the BMW iX1. The trunk opening of the GLC is higher (+1.6 in / 6%) and the narrowest width in the trunk is +3.9 in (10%) larger in the GLC.

The loading edge of the iX1 sits slightly higher (+0.4 in / 1%) above the ground.

Significant difference according to the data: The depth of the trunk (loading edge to trunk floor) is indicated as +0.8 in greater for the BMW iX1 — listed as +100% in the source.

Impact on Usability

The longer loading area of the GLC (especially with folded seats) makes it more practical for long items like slats, long boxes, or folded furniture — here the GLC wins despite moderate percentage differences due to the additional length.

The greater narrow width and higher trunk opening of the GLC also make it easier to load bulky or wide items and to lift suitcases and boxes in.

The BMW iX1 is indicated to have a significantly greater trunk depth measurement (0.8 in, listed as 100%). Practically, this means a slightly greater distance from the loading edge area to the floor of the cargo space, which can better accommodate deep or bulky items (e.g., tall boxes, stackable containers).

Since the 0.8 in difference is small in absolute terms, the practical benefit for many everyday items is only slightly noticeable — the percentage figure here likely points to a very small reference size in the comparison scale.

The slightly higher loading edge on the iX1 (+0.4 in) makes lifting heavy loads minimally less comfortable, while the slightly lower loading edge on the GLC makes loading somewhat easier.

Overall, the differences are mostly moderate: the GLC is more advantageous for longer and wider cargo, the iX1 offers slightly more usable depth in the cargo space.
