Trunk comparison: Skoda Fabia vs VW ID.4

Main Differences
The most noticeable differences concern cargo length and depth. The VW ID.4 offers a cargo area that is +11 in (20%) longer with the seats folded down than the Skoda Fabia.
Even with the first row of seats upright, the ID.4 is +7.9 in (27%) longer. Conversely, the trunk depth (distance from loading edge to trunk floor) is +3.5 in (90%) greater in the Skoda Fabia than in the ID.4.
Impact on Usability
VW ID.4 — longer cargo area: - The additional length (both with folded and upright seats) makes the ID.4 more practical for long items (e.g., skis, slats, long furniture parts) and increases the usable base area for bulky luggage. - More space with the rear bench upright means that larger suitcases or multiple travel bags can be accommodated more easily in everyday use.
Skoda Fabia — greater trunk depth: - The significantly greater depth means that cargo sits further below the loading edge.
This can be advantageous for stackable or box-shaped cargo (lower center of gravity, better securing), as well as for making smaller items less visible and less prone to shifting. - Disadvantages: with very tall items, the deep recess reduces usable vertical interior space; also, reaching down to the floor for bulky items can be less convenient.
By the way (smaller differences): - The opening height, width at the narrowest point, and opening width are within single-digit percentage ranges; the ID.4 is slightly wider at the narrow point and opening, and the loading edge of the ID.4 is marginally higher — this only moderately affects handling and loading comfort.
