Trunk comparison: Audi Q7 vs Kia Stonic

Key Differences

The Audi Q7 offers significantly more cargo length: with the seats folded down, the trunk is 26 in (+48%) longer, and with the first row of seats upright, it is 19.7 in (+72%) longer than the Kia Stonic. The trunk opening of the Q7 is also 8.7 in (+22%) wider.

In contrast, the Kia Stonic has a significantly greater trunk depth (loading edge to trunk floor): 7.1 in (+1700%) higher than the Q7. Smaller differences such as the 1.6 in higher opening height of the Stonic (+5%), the 0.4 in higher loading edge of the Q7 (+1%), or the 1.2 in wider narrowest trunk width of the Q7 (+3%) are comparatively insignificant.

Impact on Usability

Due to the significantly greater cargo length and wider opening, the Audi Q7 is clearly more practical for long and wide items (e.g., furniture, ladders, skis) and facilitates loading bulky cargo. The wider opening reduces maneuvering and angle issues when loading large parts.

The greater depth in the Kia Stonic means the trunk floor lies deeper than the loading edge: this can create more usable vertical volume and securely recess smaller items, but makes handling heavy or bulky loads less convenient because they have to be lifted or bent into a deeper "box." The slightly higher opening height of the Stonic also makes it easier to insert tall objects through the opening, but this is only a minor advantage compared to the significant length and width benefits of the Q7.

Conclusion: For transporting long or wide goods and generally higher flexibility when loading, the Audi Q7 is the better choice. The Kia Stonic offers advantages for securely storing smaller cargo due to the deeper loading floor but is less practical for bulky or heavy items.
