Trunk comparison: Kia Stonic vs VW Touran
Key Differences (only deviations >10% highlighted)
With the rear seats folded down, the VW Touran is significantly longer: +16.5 in (31%) compared to the Kia Stonic. With the first row of seats upright, the Touran also offers more cargo length: +12.6 in (46%).
In everyday mode with all seats upright, the picture reverses: the Kia Stonic has a clear advantage here with +13.8 in (103%) longer trunk space.
The depth of the trunk (loading edge to trunk floor) is 6.7 in (1700%) greater in the Kia than in the Touran. Additionally, the loading edge of the Kia is 5.9 in (24%) higher above the road.
Small note: the opening height of the Touran is +2.8 in (9%) and the opening width +2 in (5%) larger — these values are below 10% and therefore not highlighted; the narrowest width of both trunks is the same.
Impact on Usability
For long items and moving, the VW Touran is the more practical choice: its greater cargo length with folded seats and with the first row upright allows for longer loads (e.g., slats, furniture boards, skis) without having to adjust seats or seat elements. The slightly higher opening height supports loading tall items.
The Kia Stonic scores in everyday use with passengers: with fully upright seats, it offers significantly more trunk space (+13.8 in) than the Touran — better for everyday usability with full occupancy (shopping, luggage, stroller).
The much greater depth between loading edge and floor also means more usable vertical capacity in the trunk (better stacking, more room for tall items inside).
At the same time, the Kia has a higher loading edge (+5.9 in): this makes lifting heavy items into the vehicle more difficult and can be ergonomically disadvantageous during frequent loading and unloading.
With the Touran, loading and unloading is easier due to the lower loading edge, but the vertical usable height in the trunk is lower.
Width limitations practically do not matter, as the narrowest trunk width does not differ.
Overall: those who regularly transport long or bulky items and flexibly fold seats benefit more from the Touran; those who often need to accommodate luggage or tall items in the trunk with full occupancy (accepting the higher loading edge) will find the Kia Stonic the more practical solution.
