Trunk comparison: Citroen C3 vs Hyundai Kona

Key Differences
The Hyundai Kona offers significantly more usable length in the cargo space: with the seats folded down, the trunk is +11.8 in (22%) longer, and with the first row of seats upright, it is +7.5 in (28%) longer than the Citroën C3. The opening width of the Kona is +6.3 in (18%) larger, making it easier to fit bulky items through the opening.
In the Citroën C3, the depth between the loading edge and the trunk floor is +7.1 in (360%) greater, and the loading edge itself is +3.9 in (15%) higher above the ground than in the Kona.
Smaller differences: the narrowest width of the trunk is 8% larger in the Kona (not highlighted), and the height of the trunk opening is only 1% higher in the C3 (negligible).
Impact on Usability
Hyundai Kona — Advantages: Due to the longer cargo depth with seats folded or upright and the wider opening, it is easier to transport long and wide items (e.g., furniture parts, long sports equipment).
The lower loading edge of the Kona makes lifting heavy items into the vehicle easier because less lifting height is required.
Citroën C3 — Advantages and Limitations: The significantly greater interior "depth" from the loading edge to the trunk floor provides more usable vertical space directly behind the loading edge in the C3, which can be useful for stacking or transporting taller items immediately behind the edge.
However, the higher loading edge (+3.9 in) makes lifting heavy loads into the trunk more difficult; increased lifting strength or ramp assistance is beneficial here. Despite the deeper interior, the shorter cargo length and narrower opening of the C3 are disadvantages for long or wide cargo.
Conclusion: For longer and wider cargo as well as easier loading of heavy items, the Hyundai Kona is more practical.
For users who primarily benefit from additional depth directly behind the loading edge (e.g., stackable interior cargo), the Citroën C3 can be advantageous in individual cases — however, the higher loading edge reduces loading convenience.
