Trunk comparison: Kia Sportage vs Peugeot 3008

Key Differences
The Peugeot 3008 differs significantly from the Kia Sportage in two aspects: The depth of the trunk (loading edge to trunk floor) is 4.3 in (1000%) greater in the Peugeot, and the loading edge of the Peugeot is 3.1 in (11%) higher above the ground.
These two values are the only ones with more than a 10% difference and shape the practical usability of both vehicles.
What are the practical implications?
Because the loading edge of the Peugeot is higher, loading from the ground requires more lifting height than with the Kia — this makes loading heavier or bulky items at shoulder height more strenuous.
At the same time, the significantly greater depth between the loading edge and trunk floor in the Peugeot means that loaded items sit deeper in the cargo space after overcoming the loading edge; this increases the usable volume vertically but can make handling during loading and unloading more difficult (more "deep lifting" or greater lowering when removing items).
In everyday use, this means: The Peugeot tends to offer more usable interior height and thus better capacity for bulky or taller cargo, but feels less comfortable when repeatedly lifting heavy groceries or suitcases.
The Kia, with a lower loading edge and less interior step, is easier to load and unload, especially with frequent use or heavy cargo.
Other Differences (smaller deviations)
Other, smaller differences: With the seats folded down, the Kia has a cargo length 0.8 in (1%) longer, while with the first row upright, the Peugeot is 3.5 in (10%) longer.
The trunk opening of the Peugeot is 2 in (7%) higher, while the width at the narrowest point and the opening width are each 1.2 in (3%) larger in the Kia.
These differences are minor and mainly affect practical use in very specific loading tasks (wide cargo with the Kia, slightly more length with upright seats in the Peugeot).
