Trunk comparison: Audi Q5 vs Peugeot 208

Key Differences
The Audi Q5 offers significantly more usable loading length: with the seats folded down, the trunk is 13.8 in longer (≈27%), and with the front seats upright even 11 in longer (≈42%) than the Peugeot 208. The opening width of the trunk is also noticeably larger on the Q5: 10.6 in wider (≈31%).
In contrast, the Peugeot 208 has a clear advantage in another area: the depth between the loading edge and the trunk floor is 3.9 in greater (≈125%) than on the Q5.
Implications for Usability
The greater loading length of the Audi Q5 makes it much more suitable for long or bulky items (skis, long boxes, furniture parts) and for transporting several large suitcases in a row.
Combined with the significantly wider opening, wide cargo can be loaded and unloaded more easily, and bulky items can be maneuvered more simply.
The greater depth measurement of the Peugeot 208 means that the storage space forms a deeper recess vertically. This helps to store volume compactly (e.g., stacked shopping crates, tall items standing within the depth), but cannot compensate for placing very long items inside.
Depending on the configuration, a deeper loading floor can also mean that heavy goods must be lifted slightly lower, which affects loading ergonomics.
Smaller differences (e.g., opening height +1.6 in on the Q5, loading edge height +1.2 in) are less significant in everyday use and hardly change the basic usability.
