Trunk comparison: BMW X5 vs Kia Sportage

Key Differences in the Trunk

The BMW X5 offers a cargo space that is 6.7 in (≈10%) longer with the seats folded down than the Kia Sportage. The advantage is even more pronounced when the first row of seats remains upright: the X5 has 5.5 in more usable length, about 16% more than the Sportage.

The trunk opening of the X5 is also 2.8 in (≈10%) higher, and the loading edge is likewise 2.8 in (≈10%) higher above the road. Depth and width differ only slightly: loading edge depth +0.4 in (0%), narrowest width +2.4 in (≈6%), and opening width +1.6 in (≈4%) in favor of the X5.

Impact on Usability

The approximately 16% longer cargo floor with the rear seat upright makes the X5 noticeably more flexible for everyday use: longer items (e.g., skis, planks, large suitcases) and bulky loads can be transported more easily with the seats upright.

Even with the seats folded down, the X5 offers more volume (≈6.7 in longer), which is advantageous for transporting furniture or larger shopping loads.

The higher trunk opening provides more vertical clearance for tall cargo, but at the same time, the loading edge that is 2.8 in higher increases the effort required to lift heavy items into the trunk.

Those who frequently load and unload heavy items may find the Sportage more comfortable due to its lower loading edge. The smaller differences in width and depth (4–2.4 in and 0.4 in respectively) are usually negligible in practice, giving the X5 only slightly more room for wide or flat items.

Conclusion: For users who often need to transport longer or larger loads, the BMW X5 offers a clear advantage. Those who primarily value easy, low-effort loading and unloading of smaller items will tend to find the Kia Sportage more practical due to its lower loading edge.
