Trunk comparison: BMW 5 Series Touring vs Skoda Octavia Wagon

Key Differences
When comparing both wagons, two notable differences stand out: The trunk opening of the Škoda Octavia Wagon is 3.1 in (11%) higher than that of the BMW 5 Series Touring, and the trunk depth (distance from loading edge to trunk floor) of the Škoda is 3.9 in (900%) greater.
Other, smaller differences: With the seats folded down, the BMW is only slightly longer (+1.6 in / 2%), and with the first row of seats upright, both are the same length.
The loading edge of the BMW sits slightly higher (+0.8 in / 3%), the narrowest trunk width is 2.8 in (7%) larger in the BMW, and the opening width of the BMW is 1.2 in (3%) wider.
Impact on Usability
The higher trunk opening of the Škoda makes it easier to load tall items (boxes, suitcases, plants, bulky cartons) because less tilting or sideways turning is required.
The significantly greater depth in the Škoda creates more usable volume and a lower loading floor; this centers and secures heavy cargo better against shifting but can make lifting very heavy items out of the deep interior somewhat more difficult.
Since the loading edge of the Škoda is lower, this deeper floor profile is partially compensated when loading – heavy loads can be pushed over the loading edge more easily instead of lifted.
The BMW scores points with usable width: at the narrowest point and at the opening, it is somewhat more generous, which simplifies loading wider items (large furniture parts, wide cartons).
Its slightly higher loading edge makes lifting heavier loads minimally more strenuous. The almost identical length with the seats upright and only marginally greater length when folded means there are no significant differences for long cargo.
In practice, this means: For frequent transport of tall or low-positioned, heavy cargo, the Škoda is more practical. For wider, flat, or bulky items and for those needing a somewhat wider loading area, the BMW is advantageous.
