Trunk comparison: BMW iX1 vs VW Passat Wagon

Key Differences
The VW Passat Wagon offers a significantly longer cargo area with the seats folded down: +15.4 in (+24%) compared to the BMW iX1. Even with the first row of seats upright, the Passat is longer: +9.1 in (+26%).
The trunk depth (from the loading edge to the trunk floor) is +2.8 in (+350%) greater in the Passat. At the same time, the loading edge of the BMW iX1 sits +3.1 in (+13%) higher above the road than the Passat.
Impact on Usability
The longer dimensions of the Passat (both with seats folded and upright) make it more practical for longer items (e.g., furniture parts, long boxes, or skis) and provide more usable cargo space overall.
The significantly greater depth means goods can be placed further down/inward — this increases volume and makes storing bulky or tall cargo easier.
The higher loading edge of the BMW iX1 makes lifting heavy or bulky items into the vehicle more difficult; here, the Passat scores with a lower, more accessible loading area.
Smaller differences like the slightly wider opening width of the iX1 or the minimally narrower bottleneck in the Passat are of little practical relevance.
Conclusion: Those who regularly transport long, heavy, or bulky cargo will noticeably benefit from the Passat Wagon. The iX1 is sufficient for city driving and normal use but loses practicality compared to the Passat for utility purposes.
