Trunk comparison: Audi Q7 vs Mazda Mazda CX-60

Main Differences
The Audi Q7 offers a noticeably larger cargo space in length and opening width: with the seats folded down, the trunk of the Q7 is 11.8 in (17%) longer than that of the Mazda CX-60, and with the first row of seats upright, it is 8.3 in (21%) longer.
Additionally, the width of the trunk opening in the Q7 is 4.7 in (11%) larger, which makes loading and unloading wider items easier.
Smaller differences: the height of the trunk opening is 0.4 in (1%) larger in the Mazda, the loading edge of the Q7 is 1.6 in (5%) higher above the ground, the narrowest width of the Q7 is 1.6 in (4%) larger, and the depth of the trunk (loading edge to floor) is the same in both models.
Impact on Usability
The significantly greater interior length of the Q7 (17% or 21%) practically means more cargo volume for long items like slats, long boxes, or skis; the Q7 accommodates longer loading lengths both with fully folded seats and in the configuration with the first row upright.
The 11% larger opening width of the Q7 makes it easier to load wider furniture, luggage, or crates; bulky cargo fits more often without sideways turning or disassembly.
The slightly higher trunk opening on the Mazda (+0.4 in) is practically unnoticeable. The 1.6 in higher loading edge of the Q7 makes lifting heavy items somewhat more strenuous compared to the Mazda but does not reduce the usable loading area.
The minimal width difference at the narrowest point (+1.6 in on the Q7) is relevant only in a few cases. Overall, the Q7 is the more practical choice when length and loading width are needed; the Mazda offers marginally easier loading of heavy items due to the lower loading edge.
