Trunk comparison: Citroen C3 vs VW ID.3

Main Differences
The most noticeable differences concern the cargo lengths and the interior depth of the trunk. The VW ID.3 offers a cargo space that is 6.7 in (+13%) longer with the seats folded down and 4.7 in (+18%) longer with the front row upright compared to the Citroën C3. In contrast, the Citroën C3 has a trunk depth between the loading edge and the trunk floor that is 2.8 in (+44%) greater than the VW ID.3. Smaller deviations (e.g., 1.6 in/5% higher opening height on the C3, 3.1 in/9% wider trunk opening on the ID.3, or 2 in/5% larger narrowest width on the ID.3) exist but are below the 10% mark and thus less central.
Impact on Usability
Because the ID.3 offers a significantly longer loading area (
,
), it is better suited for long or flat items such as furniture boards, skis, slatted frames, or longer luggage. Even when transporting larger amounts of luggage with the rear seat still occupied, the ID.3 retains more usable length, making loading more flexible. The C3, with its significantly greater trunk depth (
), is advantageous when it comes to higher stacking heights immediately behind the loading edge or accommodating taller items in the trunk. The greater depth can also facilitate the secure storage of taller but not too long cargo. However, greater depth often means more lifting effort is required during loading because items must be lifted over a deeper trunk floor. In summary: For longer or flat-load cargo, the VW ID.3 is the more practical choice; if the goal is to accommodate higher volume directly behind the loading edge, the Citroën C3 has the advantage. Smaller differences in opening height and width only slightly affect handling.
