Trunk comparison: Kia Sportage vs Seat Ibiza

Key Differences

The Kia Sportage offers more interior length: with the seats folded down, its trunk is +11 in (≈20%) longer, and with the front seats upright, +8.7 in (≈32%) longer compared to the SEAT Ibiza. The width of the trunk opening is also significantly larger in the Sportage: +6.7 in (≈19%).

In contrast, the trunk opening of the SEAT Ibiza is higher: +3.5 in (≈12%) than that of the Sportage. The vertical shape of the cargo area is completely different: the depth from the loading edge level to the trunk floor is +7.5 in (≈1800%) greater in the SEAT Ibiza.

Impact on Usability

The longer interior dimensions and wider opening of the Kia Sportage make it more practical for long or bulky items (e.g., slats, skis, or long furniture parts) as well as for convenient loading with a flatter, continuous cargo floor after folding down the seats.

The larger opening width makes it easier to load wide boxes or luggage.

The higher opening edge and significantly greater vertical depth in the SEAT Ibiza have different practical consequences: the higher opening allows for easier insertion of tall items, while the deep recess from the loading edge level to the trunk floor means that cargo sits lower and must be lifted or lowered more when loading and unloading.

A deep cargo well can be useful for storing smaller items out of sight and limiting shifting but makes handling heavy loads more difficult.

Smaller differences such as the slightly higher loading edge in the Sportage (+1.2 in, ≈4%) or the slightly greater interior width at the narrowest point in the Sportage (+2 in, ≈5%) exist but are negligible for most everyday situations.

In summary: For longer and wider cargo, the Kia Sportage is the more practical choice. Those who frequently load tall items or benefit from a deeper cargo well (e.g., to conceal or secure smaller luggage) will find advantages in the SEAT Ibiza — albeit at the expense of usable loading length and opening width.
