Trunk comparison: Citroen C3 vs Kia Sportage

Key Differences

The Kia Sportage offers significantly more cargo length: with the seats folded down, the trunk is 13 in (24%) longer, and with the first row upright, it is 9.1 in (34%) longer than the Citroën C3. Additionally, the width of the trunk opening on the Kia is 6.7 in (19%) larger.

However, the Citroën C3 has a considerably deeper trunk floor (depth from loading edge to trunk floor) — here the difference is +9.1 in (≈2200%) in favor of the C3. Smaller differences (≤10%) include: the trunk opening of the C3 is 2.4 in (8%) higher, the loading edge of the C3 is 2.4 in (8%) higher above the ground, and the narrowest width inside the trunk is only 3.1 in (8%) larger in the Sportage.

What does this mean in practice?

Kia Sportage — better for long and wide cargo: The significantly greater cargo length both with folded and upright seats makes the Sportage the better choice for long items (e.g., furniture parts, long sports equipment) and increases usable volume with seats folded down.

The wider trunk opening makes it easier to load wide or bulky items and reduces maneuvering when loading.

Citroën C3 — better for low-placed, taller cargo in the floor area: The considerably deeper trunk floor means more usable space in depth below the loading edge, which pays off for tall items in the trunk or when storing stacked things in a deeper recess.

Due to the slightly higher loading edge (+2.4 in) and the somewhat higher opening, lifting heavy items over the threshold is a bit more strenuous; the deeper floor compensates for volume but tends to make loading and arranging a bit fiddlier.

In summary: For long and wide cargo as well as easy loading, the Kia Sportage is usually more practical in everyday use.

For cases where additional deep space (deeper floor area) is important, the Citroën C3 offers a clear advantage, with this comfort paid for by a slightly higher loading edge and thus somewhat more effort when lifting.
