Trunk comparison: Kia Sportage vs VW Polo

Key Differences
The Kia Sportage offers a cargo area that is +12.2 in (22%) longer with the seats folded down than the VW Polo. With the first row of seats upright, the Sportage is even +9.4 in (36%) longer.
The width of the Sportage's trunk opening is +5.1 in (14%) larger. Conversely, the VW Polo has a significantly greater depth between the loading edge and the trunk floor: +3.1 in (700%) compared to the Sportage.
Impact on Usability
Longer cargo area (Sportage, +22% / +36%): Practically, this means the Sportage can accommodate longer items — with folded seats, for example, skis, longer furniture parts, or construction panels; with the seat row upright, more volume for suitcases, strollers, or shopping bags in everyday use.
For users who frequently transport long or bulky loads, the Sportage is clearly more flexible.
Wider trunk opening (Sportage, +14%): The wider opening makes it easier to load wide or bulky items (strollers, boxes, furniture parts). Together with the longer cargo area, this reduces the need to angle or rotate items multiple times.
Deeper trunk well (Polo, +3.1 in / 700%): The Polo has a significantly deeper well below the loading edge.
This increases usable volume for flat or "hidden" items (tools, smaller bags), but makes lifting heavy items over the loading edge more strenuous and can complicate loading very flat, long items because they sit deeper. In short: more enclosed storage space, less comfortable loading and unloading of large, flat items.
Smaller differences (not highlighted): The Sportage's trunk opening is 1.6 in (6%) higher, the loading edge 0.8 in (3%) higher, and the narrowest width 0.8 in (2%) larger. These effects are minor and only slightly affect everyday usability.
