Trunk comparison: Fiat Panda vs Skoda Kamiq

Key Differences (highlighted: >10%)
The Škoda Kamiq offers a 16.5 in (38%) longer cargo length with the seats folded down compared to the Fiat Panda. Even with the first row of seats upright, the Kamiq is 7.9 in (37%) longer. The Fiat Panda, on the other hand, has a 0.8 in (13%) greater trunk depth (measured from the loading edge to the trunk floor).
Impact on Usability
The significantly greater length of the Kamiq is the dominant advantage for transport tasks where length matters: long items such as slats, skis, pipes, or individual furniture parts can be transported more easily and often without folding additional seats in the Kamiq.
With fully folded seats, the Kamiq offers significantly more usable cargo space and thus greater flexibility for moves or larger transports.
The greater trunk depth of the Panda means more "recess" in the loading floor and thus slightly more space in height/stackability for bulky but not very long items.
Practically, this means: bulky shopping loads or boxes can generally be stacked a bit more compactly in the Panda. Additionally, the loading edge of the Panda is slightly lower (small difference), which minimally eases lifting heavy items into the cargo area.
Other differences such as opening height or widths (each only a few percent) are relatively small and hardly affect everyday use.
