Trunk comparison: BMW X4 vs Mercedes Benz GLE

Key Differences (Highlighted)

The Mercedes‑Benz GLE offers a longer cargo space with the seats folded down: +8.7 in (≈13%) compared to the BMW X4. This is especially noticeable when transporting long items. Additionally, the trunk opening of the GLE is 4.3 in (≈16%) higher, which significantly eases loading tall or bulky cargo.

On the other hand, the BMW X4 has a noticeably greater trunk depth measurement: +3.1 in (in your data 700%) between the loading edge and trunk floor, resulting in a distinctly deeper cargo "well."

What does this mean in practice?

Due to the greater length with folded seats and the higher opening, the GLE is better suited for long or tall cargo (e.g., slats, furniture parts, bicycles with folded seats), as more usable length is available and the loading height for tall items is lower.

The larger opening height also reduces maneuvering when sliding large parts into the trunk.

The deeper trunk of the X4, on the other hand, offers advantages for securely storing smaller or irregularly shaped items: More "well height" means things lie more stably and are less likely to roll out or be visible.

This is practical for groceries, delicate cargo, or luggage stored low. However, the deeper loading floor can make loading and unloading very large, bulky objects more difficult because despite the deeper floor, the opening height and cargo length are less than those of the GLE.

Smaller Differences (Less Relevant)

Additional details: With the first row of seats upright, the GLE is only slightly longer (+3%), the loading edge of the X4 is minimally higher (+2%), the narrowest width is +5% greater in the GLE, and the width of the trunk opening is +7% larger in the GLE.

These dimensions can matter somewhat when fitting wide items or handling cargo but are less decisive in everyday use than the highlighted differences above.

Conclusion

If you often transport long or tall items, the Mercedes‑Benz GLE is the more practical choice. If you more frequently prefer smaller, securely stored, or less visible cargo, the BMW X4 offers advantages with its significantly greater trunk depth.
