Trunk comparison: BMW 5 Series Touring vs Volvo XC60

Key Differences
The BMW 5 Series Touring offers a cargo space length that is 5.1 in (14%) longer in the trunk with the first row of seats upright compared to the Volvo XC60. With the seats folded down, the BMW remains longer, but only by 4.7 in (7%).
The height of the trunk opening is 1.6 in (6%) greater on the Volvo, the width at the narrowest point is 1.6 in (4%) wider, and the width of the trunk opening is 2.4 in (6%) in favor of the Volvo.
The depth of the trunk (loading edge to floor) is the same in both models. The loading edge of the Volvo sits 2.4 in (9%) higher above the road than the BMW.
Impact on Usability
Thanks to the significantly greater loading length with the rear seats upright (14% advantage), the BMW 5 Series Touring is better suited for long items that need to be transported without folding down the rear seats (e.g., skis, long boards, or furniture parts).
The smaller advantage with folded seats (7%) exists but is less decisive.
The Volvo scores points in width and opening height: the larger opening and slightly more width make loading bulky or wide items and maneuvering in the trunk easier. The higher opening height also allows for a bit more vertical clearance for tall cargo.
The higher loading edge of the Volvo (2.4 in) makes lifting heavy items into the trunk more strenuous compared to the lower loading edge of the BMW, which is therefore more practical when frequently handling heavy loads. Since the depth of both models is the same, this dimension does not affect usability.
In short: For long cargo with the rear seats occupied, the BMW is clearly advantageous. For wider or taller but not too heavy cargo, the Volvo is more practical; for heavy loads, the BMW’s lower loading edge makes loading easier.
