Trunk comparison: BMW iX1 vs Ford S-MAX

Key Differences
The Ford S‑Max offers significantly more cargo space: with the seats folded down, the trunk is +14.2 in (22%) longer than in the BMW iX1, and with the first row of seats upright, it is +8.7 in (24%) longer.
The trunk opening of the S‑Max is also noticeably higher: it is +8.3 in (29%) higher than in the iX1, making it easier to fit taller loads.
The depth of the trunk (from loading edge to trunk floor) is only +0.4 in (50%) greater in the S‑Max — a large percentage but small in absolute terms. In contrast, the loading edge in the BMW iX1 sits +5.9 in (26%) higher above the ground than in the S‑Max.
Impact on Usability
The longer cargo areas of the S‑Max allow for transporting longer and bulkier items over the long term (e.g., furniture, bicycles with mounted wheels, or long boxes) — significantly enhancing everyday and vacation practicality.
The higher trunk opening of the S‑Max makes loading bulky, tall items easier because more interior height is available. The slightly greater trunk depth in the S‑Max is barely noticeable in centimeters in practice but slightly improves the usable interior shape.
The considerably higher loading edge height of the BMW iX1 makes lifting heavy loads into the trunk more strenuous and is unfavorable for regular loading of heavy items.
At the same time, the shorter interior length of the iX1 limits the ability to accommodate long items, restricting usability for transport. Regarding width, there are only minimal differences (each +1.2 in at certain points), which are hardly relevant for practical usability.
