Trunk comparison: BMW X5 vs Seat Ibiza

Key Differences and Impact on Usability

The BMW X5 offers significantly more usable cargo space in length and width: With the seats folded down, the trunk of the X5 is 17.7 in (32%) longer than that of the Seat Ibiza, and with the first row of seats upright, it is even 14.2 in (53%) longer.

Practically, this means long items (skis, slats, bulky furniture parts) can be more easily accommodated in the X5, and with full seating occupancy, more cargo volume remains available.

In terms of width, the X5 also has a clear advantage: The narrowest point of the trunk in the X5 is 4.3 in (11%) wider, and the opening itself is 8.3 in (24%) wider than in the Ibiza.

This makes loading and unloading wide items easier; bulky boxes, strollers, or wide sports equipment tend to fit more easily in the X5.

There are contrasting strengths regarding the loading edge and trunk depth: The loading edge of the X5 is 3.9 in (14%) higher above the ground than that of the Ibiza, which makes lifting heavy loads more difficult (more effort required to lift), but provides more ground clearance and thus potentially better off-road capability.

The depth from the loading edge to the trunk floor is 7.1 in (1800%) greater in the Ibiza than in the X5. Practically, this means the loading floor in the Ibiza sits significantly lower below the loading edge, allowing for a deeper trunk compartment — good for stacking tall items inside the trunk, but you have to reach deeper to access things.

A small difference is the height of the trunk opening: The Ibiza is only +0.8 in (3%) higher here — negligible for everyday usability.

In summary: For transport lengths and wide, bulky loads, the BMW X5 is the more practical choice. For very deep-stored cargo or when a lower loading edge to the ground (easier lifting over the street) is desired, the Seat Ibiza offers specific advantages — especially due to the greater trunk depth.
