Trunk comparison: BMW X1 vs Ford S-MAX

Biggest Differences (more than 10%)

Trunk length with seats folded down: The Ford S‑Max offers +13.4 in (21%) more length than the BMW X1.

Trunk length with front seats upright: The Ford S‑Max has +8.7 in (24%) more usable length than the BMW X1.

Height of the trunk opening: The opening of the Ford S‑Max is +8.3 in (29%) higher than that of the BMW X1.

Loading edge height above the road: The loading edge of the BMW X1 is +5.5 in (25%) higher than that of the Ford S‑Max (making the S‑Max’s loading edge significantly lower).

What impact do these differences have on usability?

The Ford S‑Max is clearly better suited for long or bulky items: The significantly greater trunk length both with folded seats and with the front seats upright allows longer items to be transported without needing to remove or heavily tilt seats.

The higher trunk opening makes it easier to load tall or bulky objects because less angling is necessary.

The significantly lower loading edge of the S‑Max makes lifting heavy loads easier and reduces physical strain when loading — a practical advantage for shopping, luggage, or heavy equipment.

For the BMW X1, the higher loading edge and shorter length lead to limitations: heavy or long cargo is harder to handle and more often requires repositioning or folding seats despite similar exterior dimensions.

The same depth of the trunk (loading edge to trunk floor) means the different usable length does not result from a different floor height but from the interior layout.

Width differences (narrowest point +0.8 in in the S‑Max, opening width +0.4 in in the X1) are very small at 1–2% and hardly relevant in practice.
