Trunk comparison: BMW 5 Series Touring vs Ford S-MAX

Key Differences

The most noticeable differences concern the vertical dimensions and the loading edge: The Ford S‑Max has a trunk opening that is 9.1 in (33%) higher than the BMW 5 Series Touring, and the depth of the trunk (loading edge to trunk floor) in the S‑Max is 1.2 in (200%) greater.

The loading edge of the BMW, on the other hand, is 3.5 in (16%) higher above the road surface than that of the S‑Max.

Impact on Usability

The higher trunk opening of the S‑Max offers significantly more vertical clearance when loading — this makes it easier to load tall or bulky items (e.g., strollers, large boxes, or furniture parts).

The greater depth between the loading edge and trunk floor in the S‑Max creates a deeper cargo area, requiring less stacking and providing more stable placement for bulky items. The lower loading edge in the S‑Max also reduces lifting effort when loading heavy loads and decreases strain on the abdomen and back.

In the BMW, the higher loading edge results in more effort when lifting heavy items and makes pushing large loads over the edge more difficult. The slightly shallower depth and lower opening height further limit handling of very tall or bulky cargo.

Other, Smaller Differences

In lengthwise direction (with seats folded down), the S‑Max is 3.1 in (4%) longer, and with the first row of seats upright, it is 1.2 in (3%) longer — both minor differences. The narrowest width of the trunk is 1.6 in (4%) greater in the BMW; the width of the trunk opening is the same in both models.

Conclusion

For users who frequently transport tall, bulky, or heavy items and value easy loading, the Ford S‑Max is more practical due to its significantly higher opening, deeper cargo floor, and lower loading edge.

The BMW 5 Series Touring offers only slightly more width at the narrowest point, which can be advantageous for flat, wide items, but is less practical when handling tall or heavy cargo.
