Trunk comparison: Kia Stonic vs VW Tiguan Allspace

Key Differences

In a direct comparison, several clear differences stand out: The VW Tiguan Allspace offers a cargo area that is 20.9 in (39%) longer with the seats folded down than the Kia Stonic. Likewise, the cargo area with the first row of seats upright is 16.9 in (62%) longer in the Tiguan Allspace.

In contrast, the Kia Stonic has a trunk that is 8.7 in (47%) larger with all seats upright. The depth of the trunk (loading edge to trunk floor) is 7.1 in (1700%) greater in the Kia.

The width of the trunk opening is 5.9 in (15%) larger in the Tiguan Allspace. The loading edge height is the same; the Stonic's trunk opening is slightly higher (+2.8 in / 10%).

Impact on Usability

For long or bulky cargo (slats, furniture, skis), the VW Tiguan Allspace is clearly advantageous: the significantly longer cargo length with folded seats and upright first row allows transporting longer items without folding additional seats. The wider trunk opening also makes it easier to load wider parts.

If all seats are occupied and luggage still needs to be carried, the Kia Stonic is more practical: it offers more usable volume (+8.7 in / 47%) with full seating, providing more storage space for shopping, suitcases, or children's gear without sacrificing seats.

The significantly greater depth of the Kia (loading edge to floor) makes storing tall or bulky items in the floor area easier — items can lie deeper and thus more stably, which is advantageous when stacking and with heavy cargo.

Since the loading edge height is the same in both vehicles, lifting onto the loading sill remains comparable.

Conclusion: Tiguan Allspace = better length and wider opening for long or wide cargo; Kia Stonic = better usable trunk space with full occupancy and deeper cargo floor for stable storage of bulky/tall items.
