Trunk comparison: BMW X2 vs Citroen C3

Key Differences

The BMW X2 offers a cargo floor that is 11.8 in (+22%) longer with the seats folded down and a trunk that is 10.2 in (+39%) longer with the front seats upright compared to the Citroën C3. The trunk opening of the C3, on the other hand, is 5.1 in (+20%) higher than that of the X2. The depth of the trunk (distance from loading edge to trunk floor) is significantly greater in the C3: +5.5 in (+156%).

Additionally, the width of the trunk opening in the BMW X2 is 4.3 in (+13%) larger than in the C3.

Impact on Usability

The longer cargo floor in the BMW X2 (both with folded seats and with the front row upright) makes it better suited for long items such as slats, furniture parts, skis, or longer boxes — requiring less folding down or allowing better storage of elongated cargo.

The wider trunk opening of the X2 facilitates loading wider parts or bulky luggage, as larger cross sections can pass through more easily.

The higher opening area and significantly greater trunk depths in the Citroën C3 favor better handling of tall or bulky cargo that requires vertical space (e.g., plants, tall boxes).

The greater depth also means that cargo sits lower in the trunk and thus more stable; this can improve usability for irregularly shaped or stackable goods. At the same time, a lower cargo floor can make lifting heavy items over the loading edge somewhat less convenient.

Smaller differences such as the slightly higher loading edge of the BMW (+0.8 in, 3%) or the minimally greater narrowest width of the X2 (+1.6 in, 4%) are usually negligible in practice.

In summary: For long and wide cargo, the BMW X2 is more advantageous; for tall, bulky, or low-sitting cargo in the trunk, the Citroën C3 is better suited. The choice depends on the typical cargo profile (length vs. height/volume).
