Trunk comparison: Hyundai IONIQ vs Skoda Fabia

Main Differences and Impact on Usability
The Hyundai IONIQ offers a significantly longer cargo area: with the seats folded down, the IONIQ is 8.7 in (16%) longer, and with the front seats upright, it is 6.7 in (23%) longer than the Škoda Fabia.
In practice, this means the IONIQ can accommodate longer items (e.g., skis, furniture parts, long boxes) more easily and provides more usable space when transporting long goods or loading with folded seats.
The Fabia, on the other hand, scores in the height and depth of the trunk area: the trunk opening is 6.3 in (24%) higher on the Fabia, and the depth from the loading edge to the trunk floor is 2.8 in (58%) greater than on the IONIQ.
This makes the Fabia more practical for tall or bulky items, facilitates loading bulky boxes, and offers more vertical storage space inside the trunk.
Other, smaller differences: the loading edge of the IONIQ is 2.4 in (9%) higher above the ground (a bit harder to lift heavy loads), the narrowest trunk width is 2.8 in (8%) larger on the IONIQ (a bit more lateral space), and the width of the trunk opening is 2.4 in (6%) larger on the Fabia (easier to fit wider items).
These values are under 10% and therefore have less practical impact.
Conclusion: IONIQ = better for long, flat loads; Fabia = better for tall, bulky, or awkward items and easier access due to larger opening and deeper cargo area. Which choice makes more sense depends on the typical cargo.
