Trunk comparison: BMW X3 vs Ford Focus

Key Differences (highlighted: >10%)

Four clear deviations emerge from the data: The BMW X3 offers a cargo space length that is 9.1 in (≈15%) longer with the seats folded down and a cargo space length that is 7.1 in (≈23%) longer with the first row of seats upright than the Ford Focus.

Additionally, the width of the trunk opening on the BMW is 4.7 in (≈12%) larger. In contrast, the Ford Focus has a significantly greater vertical dimension between the loading edge and the trunk floor: it is 7.1 in (≈1700%) lower here than the BMW X3.

Impact on Usability

The longer cargo spaces of the BMW X3 (both with folded seats and with the rear bench upright) make it more practical for long items such as boards, skis, or furniture parts: such loads fit more easily without complicated angling or extra folding of the seats.

The larger opening width (+4.7 in) also facilitates loading and unloading wider or bulkier items because there is less tight maneuvering through the rear opening.

The significantly greater distance between the loading edge and the trunk floor in the Ford Focus creates more "depth" volume: this results in more usable height in the cargo area under the shelf and can make storing taller or bulkier items easier.

At the same time, a deeper floor also means a more pronounced dip behind the loading edge: very heavy or bulky items must be lifted over the edge or pushed into a deeper recess when loading, which can make handling more difficult.

Moderate differences (trunk opening height +0.4 in, loading edge height +0.4 in, width at the narrowest point +3.5 in) are hardly noticeable in everyday use and hardly change practical usability.

Conclusion

For transports where length and width are decisive (e.g., long/flat or wide items), the BMW X3 is more practical.

Those who need more depth/vertical capacity or a larger recess in the cargo area (e.g., to hide luggage under a shelf or for tall, bulky loads) will find advantages in the Ford Focus — albeit at the cost of a somewhat more cumbersome loading process for heavy, bulky loads.
