Trunk comparison: Audi Q2 vs Audi Q5

Key Differences
Four differences stand out clearly from the data: The Audi Q5 offers a cargo length that is 8.3 in (14%) longer with the seats folded down and 6.7 in (22%) longer with the first row upright than the Audi Q2. The width of the Q5's trunk opening is 7.5 in (20%) larger.
In contrast, the distance from the loading edge to the trunk floor is 1.2 in (38%) greater in the Audi Q2 than in the Q5. All other differences (opening height, narrowest width, loading edge height) are within single-digit percentages and comparatively minor.
Impact on Usability
The greater length capacity of the Q5 (both with folded seats and upright rear bench) makes it clearly more suitable for longer items such as skis, slats, plywood, or longer luggage, as well as for transports requiring a larger usable floor area.
The significantly wider trunk opening facilitates loading bulky or wider items (e.g., bicycle frames, larger suitcases, or furniture parts) and reduces maneuvering when loading.
The higher distance from the loading edge to the trunk floor in the Q2 means a deeper cargo well: this is advantageous when frequently transporting tall or bulky but not very long items (more usable height inside before the loading edge).
Due to the narrower opening and shorter lengths, however, the Q2 is less suitable for wide or long loads and is overall better for more compact, vertically stackable cargo.
Conclusion: Those who often transport long or wide items benefit from the Audi Q5. Those who primarily have tall, compactly stackable cargo and prefer a more compact vehicle will find the Audi Q2 a practical solution — the limitations are mainly in length and opening width.
