Trunk comparison: Audi Q7 vs VW ID.4

Key Differences

The Audi Q7 offers significantly more usable length: with the seats folded down, the Q7 is 13.4 in (≈20%) longer, and with the first row of seats upright, it is 9.8 in (≈27%) longer than the VW ID.4. The width of the trunk opening is 5.5 in (≈13%) larger in the Q7. Conversely, the VW ID.4 has a significantly greater trunk depth between the loading edge and the trunk floor: the ID.4 is 3.9 in (≈900%) higher here.

Impact on Usability

These differences affect everyday usability as follows:

• More length in the Q7 (with folded or upright seats): better suited for long items (e.g., furniture parts, skis, long boxes) and more flexible loading with variable seat arrangements.
• Larger opening width in the Q7: makes loading wide or bulky items easier; bulky goods are more likely to fit without complicated maneuvering.
• Significantly greater depth in the ID.4 (between loading edge and floor): creates more vertical storage space below the loading edge and allows for "deeper" storage of luggage. At the same time, the larger recess can make lifting heavy items in and out more difficult and loading over the loading edge less practical.

Brief Assessment

For transporting elongated or wide goods, the Audi Q7 is clearly advantageous. The VW ID.4, on the other hand, offers more depth volume behind the loading edge, which can be useful for hidden or stackable cargo but affects the effort and ergonomics when loading.
