Trunk comparison: Mazda Mazda CX-5 vs Seat Ibiza

Key Differences

The Mazda CX‑5 offers significantly more cargo length: with the seats folded down, the trunk is +11.4 in (21%) longer, and with the front seats upright, even +11 in (41%) longer than the SEAT Ibiza.

The width of the CX‑5's trunk opening is also considerably larger: +7.1 in (20%). In contrast, the SEAT Ibiza has a significantly greater depth between the loading edge and the trunk floor: +5.5 in (280%) compared to the CX‑5.

Impact on Usability

For long or bulky items, the Mazda CX‑5 is clearly advantageous: the longer cargo area (both with folded seats and with the front seats upright) plus the wider opening make it easier to load slats, furniture parts, bicycles (in many cases without removing the front wheel), or longer boxes.

Wider loads can be loaded and unloaded more easily thanks to the larger opening.

The SEAT Ibiza, on the other hand, scores with the significantly greater depth from the cargo floor to the loading edge. This means more “recess” under the loading edge—useful if items are to be partially recessed below the edge or if more usable volume is desired directly behind the loading edge.

Practically, this can help position tall or irregularly shaped cargo deeper, reducing forward visibility impairment or better protecting delicate parts by recessing them.

Other smaller differences should be noted: The loading edge of the CX‑5 sits slightly higher above the road (about +2.8 in), and the narrowest width in the CX‑5 is only marginally larger (+2.4 in).

These effects are less pronounced but can be relevant when lifting heavy items (higher loading edge → more effort) or when sliding very narrow parts through.

Conclusion: For transport lengths and wide cargo, the Mazda CX‑5 is the more practical choice. Those who want to recess cargo deeper in the trunk or store items higher directly behind the loading edge benefit from the deeper trunk floor of the SEAT Ibiza.
