Trunk comparison: BMW X4 vs Citroen C3

Key Differences

The BMW X4 offers a significantly longer cargo area: +14.2 in (26%) with the rear seats folded down and +13.8 in (52%) with the front seats upright compared to the Citroën C3. The Citroën C3, on the other hand, has a higher trunk opening and depth: the opening is +3.5 in (13%) taller and the space from the loading edge to the trunk floor is +5.9 in (188%) larger than in the BMW.

Additionally, the width of the trunk opening in the BMW X4 is +5.9 in (17%) wider than in the C3.

Impact on Usability

These differences result in distinctly different everyday usability: The BMW X4 is better suited for long or wide cargo (e.g., furniture parts, long skis) because it offers more cargo length and a wider opening.

The Citroën C3 is better for tall items or storing bulky but not long cargo, as the higher opening and significantly deeper trunk well provide more vertical space.

Practically, this means: For transporting longer items, the BMW is the better choice; for bulky, tall items or easier storage further down (e.g., shopping boxes, suitcases, plants), the C3 is often more practical.
