Trunk comparison: Hyundai i10 vs VW Passat Wagon

Key Differences
The biggest difference lies in the usable length: the VW Passat Wagon offers a cargo area that is +32.7 in (≈70%) longer with the rear seats folded down and even +26 in (≈140%) longer with the front seats upright compared to the Hyundai i10. The width of the trunk opening is also significantly larger in the Passat: it is +5.9 in (≈17%) wider than in the i10. In contrast, the Hyundai i10 has a significantly greater depth between the loading edge and the trunk floor — namely +3.5 in (≈100%) — than the Passat.
Impact on Usability
The significantly greater loading length of the Passat makes it much more suitable for long or flat cargo such as furniture parts, slatted frames, long packages, or skis; even with several people on board, the Passat can accommodate considerably more cargo.
The wider trunk opening facilitates loading and unloading wider items and reduces space issues when transporting bulky parts.
The greater depth in the i10 can be advantageous when transporting taller but shorter items because more space is available below the loading edge — this helps when stacking boxes or transporting bulky, tall items that do not require much cargo length.
Overall, however, the i10 remains significantly more limited due to its compact dimensions when it comes to long or very bulky cargo.
In short: For regular transport of long or wide items, the VW Passat Wagon is the more practical choice. For short, relatively tall, or compact cargo, the Hyundai i10 can be sufficient or even advantageous.
