Trunk comparison: Kia Stonic vs Skoda Elroq

Key Differences
The Škoda Elroq offers a significantly longer cargo space when folding down the seats: +11.8 in (22%) compared to the Kia Stonic. Even with the front seats upright, the Elroq is noticeably longer: +4.3 in (16%).
In contrast, the depth of the Kia Stonic's trunk (measured from the loading edge to the trunk floor) is significantly greater: +6.7 in (1700%).
Additionally, the loading edge of the Kia Stonic sits higher above the road: +3.1 in (12%). Smaller differences under 10% include: trunk opening height (Kia +1.2 in / 4%), narrowest width in favor of the Kia (+2 in / 5%), and trunk opening width in favor of the Škoda (+1.6 in / 4%).
Impact on Usability
The longer loading length of the Škoda Elroq (especially with folded seats) makes it more practical for long items like slats, skis, furniture parts, or longer building materials – they can be stored flatter and more easily.
Even for everyday transport with the rear seats upright, the Elroq offers more usable length for suitcases or bulky bags.
The significantly greater trunk depth of the Kia Stonic means more space in the driving direction from the rear inward; this can be advantageous when stacking or hiding bulky items and often leads to greater usable volume in depth.
However, the higher loading edge of the Stonic makes lifting heavy loads more difficult and loading more strenuous for older people or with heavy items.
The smaller differences in opening and interior width are usually hardly noticeable in practice: narrow or wide trunk openings rarely change everyday usability compared to the larger differences mentioned above in length, depth, and loading edge height.
Conclusion: For frequent transport of long items, the Škoda Elroq is the better choice. For users who benefit from deeper cargo space and need more interior room in the driving direction, the Kia Stonic offers advantages, albeit at the cost of a higher loading edge and thus more difficult loading.
