Trunk comparison: BMW X1 vs Skoda Octavia Wagon

Key Differences
The Škoda Octavia Wagon offers significantly more cargo space lengthwise: with the seats folded down, the trunk is +8.7 in (13%) longer, and with the first row of seats upright, it is +7.5 in (21%) longer than in the BMW X1. The trunk depth (distance from loading edge to trunk floor) is +2.8 in (233%) greater in the Octavia.
At the same time, the loading edge of the BMW X1 is +2.8 in (11%) higher above the road than that of the Octavia. Smaller differences in width and opening size exist but remain under 10%.
Implications for Usability
The greater length reserve of the Octavia means specifically: longer items (e.g., furniture parts, skis, lumber) fit more easily, often without needing to fold down the front seats. With the seats folded down, there is overall more usable cargo space, making the wagon model ideal for transporting longer items.
The significantly greater trunk depth in the Octavia creates more volume directly behind the loading edge and allows for storing taller or bulkier items in the rear area of the trunk.
Combined with the lower loading edge of the Octavia, this noticeably eases loading and unloading heavy items or boxes—the lifting effort is less than with the higher X1 cargo floor.
The higher loading edge height of the BMW X1 means more effort is required to lift bulky or heavy loads into the trunk. BMW's advantages lie more in a slightly greater width at the narrowest point and a somewhat wider opening, which can help when fitting very wide but flat items.
Overall, however, the Octavia is the more practical choice when it comes to longer, taller, or bulkier cargo and easier loading and unloading of luggage.
