Trunk comparison: Audi Q5 vs Kia Stonic
Key Differences
When comparing the trunks, several clear differences stand out: The Audi Q5 offers a cargo space that is +11.4 in (21%) longer with all seats folded down and +10.2 in (38%) longer with the first row of seats upright compared to the Kia Stonic. The width of the trunk opening is +5.5 in (14%) larger in the Audi.
Conversely, the Kia Stonic has a significantly greater trunk depth measurement (loading edge to trunk floor) of +3.9 in (125%) compared to the Audi. The height of the trunk opening is the same in both models.
Smaller differences: the Kia's loading edge is only +1.2 in (4%) higher above the ground, and the narrowest trunk width is only +0.8 in (2%) larger in the Kia — these values are minor.
Impact on Usability
More length and a wider opening in the Audi Q5 practically mean: longer items (e.g., furniture parts, skis, long boxes) can be stored more easily and flatly, and wide cargo passes through the opening more easily.
This makes the Q5 more practical for everyday use with larger transports and for users who often need to load bulky or long items.
The greater trunk depth measurement in the Kia Stonic suggests a deeper cargo area below the loading edge. This can be advantageous for discreetly storing smaller items or better utilizing the cargo space in depth.
At the same time, a deeper compartment combined with only a slightly higher loading edge (only +1.2 in) means that heavy or bulky items have somewhat less favorable leverage when lifting in and out — loading and unloading can therefore be more strenuous than in the Q5.
Since the trunk opening height is the same in both models, this factor does not influence usability in favor of either vehicle. Minor width differences at the narrowest point and the slightly higher loading edge of the Kia are negligible for most everyday scenarios.
In summary: For transporting long or wide items, the Audi Q5 is the more practical choice. For deeper, well-stowable cargo, the Kia Stonic offers advantages, while for heavy or bulky cargo, loading and unloading is easier in the Q5.
