Trunk comparison: Audi Q7 vs Durchschnitt Subcompact

Key Differences (highlighted)
The Audi Q7 offers significantly more cargo length: +29.5 in (59%) with seats folded down and +22 in (89%) with the first row upright compared to the average subcompact.
The width of the trunk opening is +11.8 in (33%) larger on the Q7. Another notable difference concerns the floor depth: The distance from the loading edge to the trunk floor is +7.5 in (1800%) greater in the average subcompact than in the Audi Q7, meaning the subcompact has a noticeably deeper well below the loading edge.
Impact on Usability
More length and a significantly wider opening on the Q7 make it considerably more practical for long or wide items (e.g., furniture, skis, slats, pallets) and for situations where luggage and passengers need to be transported simultaneously.
Even with the first row upright, the Q7 retains significantly more usable cargo space, making it more flexible for everyday and occasional transport needs.
The deeper well in the subcompact creates a step just behind the loading edge. This can benefit smaller items that remain securely in place but reduces the practical loading surface for long objects and makes loading and unloading bulky cargo more difficult.
Heavy cargo in the subcompact often needs to be lifted into or out of the well, which can be less convenient.
Smaller differences below the 10% threshold: The height of the trunk opening is 2.4 in (≈8%) higher in the subcompact, and the Q7’s loading edge is 2 in (≈7%) higher above the ground. The narrowest interior width of the Q7 is about 10% larger (+3.9 in)—this is borderline but not highlighted here as >10%.
These factors moderately affect daily use: a slightly higher loading edge on the Q7 makes lifting heavy items minimally more strenuous, while the somewhat higher opening height on the subcompact can help when loading very tall items.
Conclusion: For transporting long, wide, or bulky items and for flexible use with passengers, the Audi Q7 is clearly better suited. The average subcompact offers storage space for compact loads due to its deeper well and shorter lengths but is less practical for larger loads and comfortable loading and unloading.
