Trunk comparison: BMW iX1 vs Skoda Fabia

Key Differences and Implications for Use
The BMW iX1 offers with folded seats a trunk that is 8.3 in (15%) longer than the Skoda Fabia and with the first row of seats upright even 6.3 in (22%) more cargo depth.
This makes the iX1 significantly better suited for long items (e.g., skis, long boxes, furniture parts) and for users who regularly need to transport longer cargo even when passengers are seated.
The Skoda Fabia, on the other hand, scores in vertical accessibility: the trunk opening is 3.9 in (14%) higher and the depth from the loading edge to the trunk floor is 6.7 in (850%) greater than in the iX1. Practically, this means: bulky or tall cargo can be maneuvered more easily through the opening in the Fabia, and the deeper trunk floor creates more usable interior height, allowing for taller stacks or bulky items to sink deeper.
At the same time, the deeper loading well creates a larger step when removing heavy items.
Other differences: The iX1 has a slightly greater width at the narrowest point (+2.8 in / 8%) and a slightly wider trunk opening (+3.5 in / 9%), plus the loading edge of the iX1 is about 1.6 in higher above the road than the Fabia.
These smaller deviations support loading wider items and only slightly affect loading and unloading.
Conclusion: For longer or regularly changing, length-oriented cargo, the BMW iX1 is the more practical choice. For transport tasks where taller or bulkier items need to fit vertically through the opening and into a deeper loading well, the Skoda Fabia is better suited.
Which option is more advantageous thus depends on the usual type of cargo: length and surface utilization favor the iX1, vertical usable height and deeper loading well favor the Fabia.
