Trunk comparison: Audi Q5 vs Kia Sportage

Key Differences
Among the measured values, one difference stands out clearly: The depth of the trunk (distance from loading edge → trunk floor) of the Audi Q5 is +3.1 in (≈700 %) larger than that of the Kia Sportage.
All other differences are below the 10% mark: Kia has a +1.2 in longer cargo floor with the seats folded down, the Audi offers +2 in with the first row upright, the trunk opening of the Audi is +2.4 in higher and +3.1 in wider, the loading edge of the Audi is +0.8 in higher above the road, and the narrowest trunk width is +0.4 in larger on the Kia.
Impact on Usability
The significantly larger trunk depth value in the Audi Q5 practically means more usable vertical and depth extension in the cargo space: taller or bulkier items can be loaded more easily or stand more freely, and stacking is easier in many cases.
This makes the Audi especially suitable for transporting crates, large suitcases, sports equipment, or bulky items.
Compared to the Audi, the Kia Sportage offers a minimally longer cargo floor with folded seats and a comparatively narrower but almost identical opening geometry — however, these deviations are minor and usually have little effect in everyday use.
The slightly higher loading edge in the Audi (+0.8 in) can make loading heavy items slightly more difficult but is partially compensated by the greater depth and the somewhat wider opening (+3.1 in).
Conclusion: For users who frequently transport tall or bulky loads, the Audi Q5 offers a noticeable practical advantage due to the significantly larger trunk depth. Smaller length and width differences between the models are less relevant in daily use.
