Trunk comparison: Audi Q5 vs Hyundai Kona

Key Differences
With the seats folded down, the lengths of both trunks are the same. With the first row of seats upright, the Audi Q5 is 3.5 in (≈10%) longer than the Hyundai Kona. The height of the trunk opening in the Q5 is only 0.4 in (1%) higher than that of the Kona.
The width at the narrowest point is 0.4 in (1%) larger in the Kona, while the width of the trunk opening is 3.5 in (9%) larger in the Q5. The loading edge of the Q5 sits 2.4 in (9%) higher above the road than in the Kona.
The depth of the trunk (loading edge → trunk floor) differs significantly: the Audi Q5 is +1.2 in deeper, which corresponds to an increase of about 60% compared to the Kona.
Impact on Usability
The significantly greater depth in the Q5 practically means more usable vertical capacity behind the loading edge: items can be recessed deeper, creating more storage space for taller or stacked cargo beneath the trunk cover.
This makes it easier to securely store bulky or unstable items and reduces the risk of light cargo sliding forward during braking.
On the other hand, the Q5 has a slightly higher loading edge (+2.4 in) — this makes lifting heavy items somewhat more strenuous, but with a 9% difference it is relatively moderate.
The greater width of the trunk opening in the Q5 (+3.5 in) facilitates loading wider items; the identical overall length when closed (seats folded) means both models offer the same maximum cargo length when fully utilized.
Conclusion: For users who frequently need to secure taller or stacked cargo, the Q5 offers a noticeable advantage due to its significantly greater depth.
Those who primarily value a lower loading edge or minimal exterior dimensions benefit from the Kona’s slightly lower loading edge height and overall more compact proportions — however, the differences here are minor.
