Trunk comparison: VW Passat Wagon vs Durchschnitt Subcompact

Key Differences
The VW Passat Wagon offers significantly more cargo length: with the seats folded down, the trunk is +28.7 in (57%) longer, and with the first row of seats upright, even +19.7 in (79%) longer compared to the average subcompact. Additionally, the width of the trunk opening on the Passat is +5.5 in (15%) larger.
In contrast, the average subcompact has a significantly greater trunk depth (loading edge to trunk floor) of +3.9 in (111%) as well as a higher loading edge above the road by +3.5 in (14%) compared to the Passat. Differences under 10% (e.g., trunk opening height +3%) are negligible and hardly affect practical use.
Implications for Usability
The significantly greater cargo length and wider opening of the Passat make it noticeably more practical for long or wide loads (e.g., slats, furniture parts, long sports equipment). The wider opening makes it easier to load bulky items without repositioning.
The lower loading edge of the Passat (the subcompact is +3.5 in higher here) reduces the effort needed to lift heavy items and makes removing large loads easier. Combined with the greater usable length, this results in significantly better everyday usability when loading and unloading.
The greater depth in the subcompact (trunk floor significantly lower below the loading edge) can create more "vertical volume," but makes practical loading less convenient: due to the higher loading edge, more lifting or carrying is required, and bulky long items are harder to accommodate because of the shorter usable length.
Overall, the Passat wins in transport-related usability; the subcompact offers more floor depth in certain cases but hardly any advantages in comfort or handling when loading.
