Trunk comparison: BMW X4 vs Peugeot 5008

Core Differences

When comparing the two models, several differences stand out clearly: The BMW X4 offers a significantly longer trunk with seats upright (+26.8 in / 200%), meaning it provides considerably more usable loading length in everyday use without folding the seats down.

This is practical for longer luggage, sports equipment, or bulky shopping items that are frequently transported without folding seats.

The Peugeot 5008, on the other hand, scores with a higher trunk opening (+3.9 in / 14%) and a greater interior width at the narrowest point (+5.9 in / 15%).

This makes loading tall or wide items significantly easier: larger boxes, strollers, or furniture pieces can be slid in and turned more easily. Additionally, the trunk opening of the Peugeot is overall wider, which facilitates maneuvering bulky cargo.

In the BMW X4, the depth of the trunk (loading edge to trunk floor) is significantly greater (+2.8 in / 700%) and the loading edge itself is higher above the road (+3.9 in / 14%).

Together, these values mean: more space inside between the loading edge and floor (which can support stacking or picking up lower-lying items), but a higher loading edge that makes lifting heavy loads during loading more difficult.

In practice, this means the BMW can offer more "depth" inside for certain geometries but requires more strength or aids when handling heavy, deep items.

Consequences for Usability

For drivers who regularly transport long items without folding seats (e.g., sports equipment, long boxes), the BMW X4 is the more practical choice due to the significantly greater usable length with seats upright.

However, those who more frequently load wide, tall, or bulky objects (strollers, furniture parts, large crates) or value easy loading and unloading benefit from the Peugeot 5008: the higher opening and greater interior width make storing and turning bulky cargo easier.

Those who often lift heavy loads should consider: the higher loading edge of the BMW increases the effort required when loading compared to the Peugeot. Conversely, the greater trunk depth of the BMW can be advantageous for specific cargo shapes if the geometry of the items benefits from it.

Summary

BMW X4: clear advantage in usable length without folding seats; higher loading edge makes lifting heavy items more strenuous, trunk depth can be useful for certain loads. Peugeot 5008: more accessible, higher, and wider loading opening at critical points — overall easier and more flexible for wide/tall or bulky items.
