Trunk comparison: BMW X5 vs Ford Focus Wagon

Key Differences

The main differences concern the vertical dimensions and the loading edge: The height of the trunk opening of the BMW X5 is 3.5 in (13%) larger than that of the Ford Focus Wagon.

The depth of the trunk (loading edge to trunk floor) is 0.4 in (100%) larger in the Ford Focus Wagon than in the BMW X5. The loading edge of the BMW X5 is 6.3 in (25%) higher above the ground than that of the Focus.

Other, significantly smaller differences: with the rear seats folded down, the BMW is only 0.8 in (1%) longer; with the front seats upright, the lengths are the same; the narrowest trunk width is 1.2 in (3%) larger in the Focus, and the trunk opening of the BMW is 0.4 in (1%) wider.

Impact on Usability

The larger trunk opening of the BMW X5 (≈+3.5 in / 13%) makes it easier to load taller items (e.g., bulky boxes, furniture parts, or tall plants) and reduces the risk of bumping when loading.

However, the significantly higher loading edge of the X5 (≈+6.3 in / 25%) makes lifting heavy loads more strenuous and is ergonomically disadvantageous for frequent loading of heavy items; rolling suitcases or trolleys can be pushed in more easily in the Focus.

The nominally greater depth in the Focus (+0.4 in, 100% relatively) is only 0.4 in in absolute terms, so it practically has little impact on usable cargo space but explains why the floor/edge area in the Focus sits slightly lower.

Length and width differences are so minor that they hardly cause noticeable restrictions in everyday use: usable lengths are basically the same, and width differences of 1–1.2 in hardly affect which luggage fits.

Conclusion: For loading tall or bulky items, the BMW X5 is advantageous; for frequent lifting of heavy loads or comfortable pushing in of rolling cargo, the Ford Focus Wagon is more practical due to the significantly lower loading edge. Volume and width advantages are negligible.
