Trunk comparison: Audi Q7 vs Durchschnitt Compact SUV

Key Differences
The Audi Q7 offers a significantly longer cargo space: when all seats are folded down, the trunk is 21.3 in (+36%) longer, and with the first row of seats upright, it is 16.5 in (+55%) longer than the average compact SUV.
The width of the trunk opening in the Q7 is 9.4 in (+25%) larger, making access to bulky items noticeably more comfortable. In contrast, the cargo floor of the average compact SUV sits significantly lower: the depth (loading edge ↔ trunk floor) is 5.5 in (+1300%) greater than in the Q7.
Impact on Usability
The longer interior dimensions of the Q7 make it better suited for long items (e.g., slats, skis, furniture parts): even with seats upright, significantly longer items fit without folding seats down. The wider opening greatly facilitates loading wide or awkward cargo.
The deeper cargo space of the average compact SUV means more vertical room in the trunk — advantageous for tall or stacked cargo — however, the loading floor sits lower in the vehicle, which can either make lifting heavy items easier (less lift height) or favor storing near the floor, depending on handling.
Smaller differences like the narrowest interior width (+10% in the Q7) exist but are less significant compared to the points mentioned above.
