Trunk comparison: Audi Q7 vs Volvo XC40

Key Differences
The Audi Q7 offers with folded seats a cargo length that is 13.8 in or 21% longer than the Volvo XC40. Even with the first row of seats upright, the Q7 remains significantly longer: plus 11 in or 31%.
Additionally, the trunk opening width of the Q7 is 5.9 in or 14% larger than that of the XC40. The depth (loading edge to trunk floor) is the same in both models.
What impact does this have on usability?
The significantly greater length of the Q7 (both with folded and upright seats) makes it more practical for long items such as skis, canoes, long furniture parts, or Euro pallets – such loads fit more often in the Q7 without awkward angling or disassembly.
The larger opening width makes loading bulky or awkward items easier and reduces the risk of damaging edges or interior trim.
Other differences are more minor: The height of the trunk opening is 0.8 in (3%) greater in the Q7, and the loading edge is 1.2 in (4%) higher above the ground; both are only marginal influences on everyday usability (easier sliding in vs. slightly higher lifting).
The narrowest width of the trunk is 2.8 in (7%) larger in the Q7, which helps but is not as strong an advantage as the longer dimensions and wider opening.
