Trunk comparison: BMW iX1 vs Skoda Kamiq

Key Differences and Consequences for Usability
The BMW iX1 offers a longer cargo floor with the front seats upright: +6.3 in (≈22%) compared to the Škoda Kamiq. This makes the iX1 significantly more practical if you regularly transport longer items without folding down the rear seats (e.g., boards, skis, long boxes).
The Škoda Kamiq has a higher trunk opening: +4.7 in (≈17%) and especially a significantly deeper cargo well (loading edge to trunk floor): +5.5 in (≈700%).
Together, these differences mean the Kamiq is better suited for bulky or tall items — you benefit from more vertical clearance when loading and a deeper cargo floor where bulky or tall cargo can be better and more securely stowed.
The deeper cargo well also lowers the center of gravity of the load and makes it easier to store tall, bulky boxes.
Smaller differences, which do not exceed 10%, only slightly affect usability: The iX1 has a slightly higher loading edge (+0.8 in, ≈3%) and a +2.8 in (≈7%) wider trunk opening as well as +0.4 in (≈1%) more width at the narrowest point.
This results in slightly better width usability for flat, wide cargo in the iX1, while the somewhat higher loading edge makes lifting heavy items a bit more strenuous.
Practical recommendation: Those who often transport long, flat items and value longer cargo space with seats upright are better served by the BMW iX1. Those who frequently carry tall, bulky, or awkward cargo or value an easily accessible, deep cargo well benefit more from the Škoda Kamiq.
