Trunk comparison: Volvo XC40 vs Volvo XC60
Key Statement
The Volvo XC60 offers overall slightly larger cargo spaces than the XC40: With the seats folded down, the trunk of the XC60 is 3.9 in (6%) longer, and with the first row of seats upright, it is 2 in (5%) longer. The width at the narrowest point is 3.9 in (10%) greater in the XC60, the width of the trunk opening is 2.4 in (6%) wider, and the height of the opening is 0.4 in (1%) higher. Depth (loading edge to floor) is the same, but the loading edge of the XC40 sits 1.2 in (4%) higher above the road than that of the XC60.
Note on Highlighting
No measured difference exceeds 10%. The largest difference is the width at the narrowest point with exactly +10% in favor of the XC60; I highlight this difference as the most important:

Impact on Usability
The greater narrowest width in the XC60 makes loading bulky, wider items noticeably easier: wide boxes, strollers, or bulky furniture pieces are more likely to fit without awkward maneuvering. The 3.9 in longer cargo space with folded seats allows longer items (e.g., slats, skis, or long boxes) to be transported more stably and flat; however, the advantage is moderate (6%). The 2.4 in wider trunk opening of the XC60 also slightly facilitates loading wider cargo. The lower loading edge of the XC60 (the XC40 sits 1.2 in higher) reduces the effort required to lift heavy items in and out — practical for regular transport of groceries, beverage crates, or toolboxes. Since the trunk depths are identical and the opening heights vary by only 0.4 in, packing habits in height change little. In summary: The XC60 offers noticeable but moderate advantages when transporting wider and longer items as well as somewhat easier loading and unloading. For everyday use with frequent transport of bulky items, the XC60 tends to be more practical; for occasional transport, the differences are rather small.
