Trunk comparison: BMW X2 vs Peugeot 5008

Key Differences and Impact on Usability
The data consistently show significant differences between the models that have practical effects:
With the seats folded down, the Peugeot offers a cargo space that is 8.7 in (13%) longer than the BMW. This makes the 5008 significantly more practical for long items or bulky loads (e.g., furniture parts, slats, disassembled bicycles) when the rear seats are not in use.
With the first row of seats upright, the Peugeot is 4.7 in (13%) longer than the BMW. This means more usable cargo space behind the front row in typical family or passenger use.
However, when all seats are upright, the BMW has a trunk that is 23.2 in (174%) longer than the Peugeot. This is relevant if you often drive fully occupied and still want to carry a comparatively large amount of luggage behind the seats — here the BMW clearly has the advantage.
The Peugeot’s trunk opening is 5.5 in (21%) higher than the BMW’s, and the width at the narrowest point is 5.9 in (15%) greater; the opening width is 5.5 in (14%) larger. Taken together, this significantly facilitates loading and unloading wide or bulky items (strollers, wide suitcases, shelves) in the Peugeot.
The BMW has a trunk depth (loading edge to trunk floor) that is 3.1 in (800%) greater and a loading edge that is 4.3 in (16%) higher above the road.
Practically, this means the BMW offers a deeper cargo well (more hidden volume), but the higher loading edge makes lifting heavier items more strenuous. The Peugeot has the more ergonomic, lower loading edge, making loading and unloading heavy loads easier.
Conclusion on usability: If you often transport long or wide items and value easy loading access, the Peugeot 5008 is better suited due to the longer cargo length with folded seats, larger opening, and lower loading edge.
If, on the other hand, you frequently travel with all seats occupied and still want to accommodate a comparatively large amount of luggage behind the seats, the BMW X2 offers more usable space in this configuration — it also has a deeper cargo well for more hidden volume, but at the cost of more difficult handling when lifting due to the higher loading edge.
