Trunk comparison: Kia Sportage vs Durchschnitt Wagon

Key Differences
With the rear seat folded down, the difference is small; the average wagon offers only +1.6 in (2%) more trunk length than the Kia Sportage. However, with the front seats upright, the wagon has a noticeably longer cargo area: +3.9 in (11%) compared to the Sportage.
The trunk opening of the wagon is nominally higher (+2.4 in / 8%), the narrowest width of both models is the same, and the opening width of the Sportage is only marginally larger (+0.4 in / 1%).
Notably: The trunk well (distance from loading edge to trunk floor) of the wagon is significantly more pronounced — about +1.6 in (≈300%) compared to the Sportage. Additionally, the loading edge of the Kia Sportage sits higher above the road surface: +3.5 in (14%) compared to the average wagon.
Impact on Usability
The longer cargo area of the wagon with upright seats (+11%) makes it more practical for everyday use without folded seats: longer luggage, ski bags, or suitcases fit more easily without reducing seating. If you often transport with a full seat load, the wagon clearly gains an advantage.
The significantly deeper trunk well of the wagon means more usable volume "in the recess" of the cargo area — larger or bulkier items can be stored further down, increasing transport capacity for bulky loads. However, items lie deeper and are somewhat harder to reach when loading and unloading.
The higher loading edge of the Sportage (+3.5 in / 14%) negatively affects lifting heavy loads in practice: lifting into the trunk requires more effort, making loading and unloading bulky items more cumbersome.
Conversely, a higher loading edge better protects the cargo from lateral shifting and can provide increased ride comfort with a high floor, but it is a disadvantage for pure loading handling.
Conclusion: For users who often transport longer or bulkier items with a fully occupied rear seat and prefer easier loading and unloading, the average wagon is more practical due to the longer cargo area (with upright seats), the deeper trunk well, and the lower loading edge.
The Kia Sportage offers nearly the same length only with folded seats and has a slightly larger opening width but sacrifices comfort when lifting heavy loads.
