Trunk comparison: Hyundai Kona vs Nissan Rogue Sport

Key Differences
Most dimensions are very close: trunk length with folded seats differs by only 0.4 in (Kona +0.4 in), and with the first row upright, the Qashqai is also only 0.4 in longer — both about ~1%.
The height of the trunk opening is +0.8 in (3%) larger on the Qashqai, and the width of the opening is +3.1 in (8%) larger on the Qashqai. The narrowest width inside the trunk is the same for both models.
Significantly larger differences exist in the trunk layout: The Qashqai has a loading area that is 0.4 in deeper (loading edge → trunk floor), which corresponds to a difference of about +20%. Additionally, the loading edge of the Qashqai is 3.5 in higher than on the Kona, which is about +13%.
Impact on Usability
The greater trunk depth of the Qashqai (20% more) practically means more usable interior space in depth: bulky or taller items can be better accommodated, stacked cargo gains space, and folded seats offer slightly more volume vertically.
The wider opening (+3.1 in) supports loading wider items but is not a major advantage in quantity compared to the Kona.
On the other hand, the higher loading edge of the Qashqai (+3.5 in / 13%) makes loading and unloading heavy or awkward loads more difficult in everyday use — shopping bags, strollers, or heavy boxes need to be lifted higher.
For frequent lifting or users with limited strength, the Kona is more practical due to the lower loading edge.
In summary: For transporting taller/stacked or bulky items, the Qashqai offers advantages due to its deeper loading area; for frequent, comfortable loading and unloading of heavy items, the Kona is more comfortable thanks to the lower loading edge.
All other differences are minor and only minimally affect everyday usability.
