Trunk comparison: Audi Q7 vs Tesla Model Y

Key Differences
The Audi Q7 offers significantly more space than the Tesla Model Y in several areas.
Notable are three differences over 10%: The loading edge of the Q7 is 3.1 in (+11%) higher than that of the Model Y; the narrowest width in the trunk of the Q7 is 5.1 in (+14%) larger; and the width of the trunk opening of the Q7 is 7.9 in (+20%) larger.
Other, smaller advantages of the Q7: with the seats folded down, the trunk is 3.5 in (+5%) longer, with the first row of seats upright it is 3.1 in (+7%) longer, and the height of the trunk opening is 2.4 in (+9%) higher. The depth (loading edge to trunk floor) is the same in both models.
Impact on Usability
The significantly greater width of the trunk opening (+20%) and the larger narrow interior width (+14%) make the Q7 clearly more practical for wide or bulky cargo (e.g., furniture pieces, wide boxes, sports equipment). Larger items can be angled more easily and maneuvered through the opening.
The higher loading edge of the Q7 (+3.1 in / +11%) has the opposite effect: heavy cargo must be lifted higher, making loading and unloading more strenuous and less ergonomic with frequent use than with the Model Y, whose lower loading edge facilitates handling heavy loads.
The slightly greater length of the Q7 with folded seats or with the first row upright (+5–7%) and the somewhat higher opening (+9%) are advantageous but remain secondary compared to the width differences.
Since the depth is the same, both models are comparable for long, flat items as long as they fit through the opening.
Conclusion: For regular transport of wide or bulky items, the Audi Q7 is the more practical choice due to the larger opening and interior width. Those who frequently load and unload heavy but not particularly wide loads benefit from the lower loading edge of the Tesla Model Y.
