Trunk comparison: Audi Q7 vs VW ID.3

Key Differences (highlighted: >10%)

The Audi Q7 offers significantly more cargo length: with the seats folded down, the trunk of the Q7 is 19.7 in (≈33%) longer and with the first row upright, 15.7 in (≈51%) longer than the VW ID.3. The width of the Q7's trunk opening is 9.8 in (≈26%) larger than that of the ID.3. Conversely, the VW ID.3 has a significantly greater internal depth measurement from the loading edge to the trunk floor: the depth is 6.3 in (≈1500%) higher than the Q7.

Not significantly different (>10%) are the height of the trunk opening (equal) and the loading edge height (Q7 only ≈1% higher). The narrowest trunk width is about ≈7% larger in the Q7 — which is below the 10% threshold.

What impact do these differences have on usability?

The greater cargo length of the Q7 makes it better suited for long or bulky items (e.g., furniture boards, long tools, skis). The wider trunk opening also facilitates loading and unloading wider items and reduces issues when passing through tight openings.

The significantly greater depth in the ID.3 means the interior floor lies much lower than the loading edge: this creates a "deep tub" where bulky or tall items can partially disappear below the loading edge — practical when you want to use more volume without blocking the tailgate.

At the same time, this deep recess can make lifting heavy items more difficult (greater vertical distance to place them) and complicates reaching items on the trunk floor.

Since the loading edge height is practically identical, loading from height remains similar for both models; the Q7 feels overall more practical for wide and long cargo due to its length and wider opening, while the ID.3 scores with "deep" loads and protected storage of volume below the loading edge.
