Trunk comparison: Kia Stonic vs Peugeot 3008

Biggest Differences

Peugeot 3008 offers a significantly longer cargo area: with the seats folded down, the trunk is +11.8 in (22%) longer, and with the front row upright, even +11.8 in (43%) longer than the Kia Stonic.

In contrast, the Kia Stonic has a significantly greater trunk depth (loading edge to trunk floor): +2.8 in (64%) compared to the Peugeot.

Other differences (less than 10%) are minor: the height of the trunk opening is +0.4 in (1%) larger on the Kia, the loading edge of the Peugeot is +1.2 in (4%) higher above the road, the narrowest trunk width is +1.6 in (4%) larger on the Kia, and the opening width is +1.2 in (3%) larger on the Peugeot.

Impact on Usability

The longer loading length of the Peugeot makes it more practical for long or flat items (e.g., furniture panels, bicycles with disassembly, long boxes).

This advantage is especially pronounced when the front row remains upright: more loading length with a full passenger count means greater versatility for trips with luggage.

The significantly greater depth of the Kia means more usable vertical or tiered cargo capacity in the area behind the loading edge — practical for taller or stackable luggage, boxes, or equipment that lies more securely in a deep recess.

Together with the lower loading edge of the Kia (since the Peugeot’s loading edge is 1.2 in higher), handling heavy items is generally easier with the Kia.

Smaller width and height differences are negligible for most everyday cases: the marginally larger opening width of the Peugeot and the slightly greater narrow interior width of the Kia only affect very wide loads.

Conclusion

In short: Those who frequently transport long, flat, or bulky items and need plenty of space with the front row upright benefit more from the Peugeot 3008. Those who often carry heavy, tall, or stacked cargo and appreciate easier lifting over the loading edge are better served by the Kia Stonic.
