Trunk comparison: Kia Ceed vs Mercedes Benz GLC

Biggest Differences (highlighted)

The Mercedes‑Benz GLC offers a longer cargo area with the seats folded down: +8.3 in (+14%) compared to the Kia Ceed. Even with the first row of seats upright, the GLC is longer: +5.5 in (+18%).

In contrast, the Kia Ceed has a significantly greater trunk depth (distance from loading edge → trunk floor): +4.3 in (+1000%) compared to the GLC.

What are the practical implications of these differences?

The longer cargo area of the GLC (both with folded and upright seats) makes it better suited for long items (e.g., slats, skis, longer furniture parts) and for significantly more luggage on long trips or moves. Those who regularly transport bulky or longer loads have noticeably more room in the GLC.

The greater depth in the Kia Ceed means the trunk floor sits deeper below the loading edge. This increases the effective capacity in the cargo space for lower, bulky items and more easily prevents smaller parts from shifting.

However, the cargo floor being lower can make loading very large or wide items (that don’t fit flat in the well) more difficult.

Other smaller effects from the remaining values: The loading edge of the GLC is slightly higher (+2 in / 8%), which makes lifting heavy loads a bit more strenuous; the width of the trunk opening is 3.9 in larger in the GLC (borderline, not >10%), which facilitates loading wider items.

Differences in opening height (+0.4 in) and narrowest width (+2.8 in / 7%) are hardly noticeable in practice.

Conclusion: For long or many pieces of luggage and bulky cargo, the GLC is the more practical choice. For everyday use with lower, bulky items or when a deep cargo well and easier handling at floor level are important, the Kia Ceed offers advantages.
