Trunk comparison: Peugeot 5008 vs Volvo XC40

Key Differences (highlighted)
The Peugeot 5008 offers a significantly larger cargo area with the seats folded down: +7.9 in (12%) more loading length than the Volvo XC40. Even with the first row of seats upright, the Peugeot stands out with a +5.5 in (15%) longer loading area.
Additionally, the trunk of the Peugeot is 5.5 in (14%) wider at its narrowest point. In contrast, the Volvo XC40 has a significantly larger trunk with all seats upright: +22.4 in (168%) more cargo space than the Peugeot.
What does this mean for usability?
Because the Peugeot offers longer cargo volume, it is better suited for long items and irregularly shaped loads that require space along the vehicle's length (e.g., long boxes, furniture parts, or sports equipment). The greater narrowest width also makes it easier to maneuver wider items through the trunk.
The Volvo XC40, on the other hand, clearly has the advantage when all seats are in use: Its significantly larger trunk with seats upright makes it more practical for full occupancy with luggage — for example, family or vacation trips where multiple passengers need to carry luggage simultaneously.
Other, smaller differences
The trunk opening of the Peugeot is slightly higher (+2.8 in, 10%), the loading edge of the Volvo is higher (+2.4 in, 9%), and the difference in trunk depth is negligible (+0.4 in).
The width of the trunk opening is somewhat larger on the Peugeot (+2.8 in, 7%), but remains below the 10% threshold and is therefore less noticeable.
