Trunk comparison: Opel Grandland vs Seat Ibiza
Key Differences
The Opel Grandland offers significantly more length in the cargo space: with the seats folded down, the trunk is 11 in (20%) longer, and with the first row upright, the advantage is even 8.3 in (31%).
The width of the trunk opening is also clearly advantageous in the Grandland: 7.9 in (23%) larger than in the SEAT Ibiza.
However, the loading edge of the Grandland is 3.5 in (13%) higher above the ground.
In the SEAT Ibiza, the depth between the loading edge and the trunk floor is 1.2 in (19%) greater, the height of the trunk opening is only slightly higher (+0.4 in / 1%), and the narrowest width of the trunk differs only slightly (+0.8 in / 2% in favor of the Grandland).
Implications for Usability
For longer or bulky items (e.g., furniture parts, skis, long boxes), the Grandland is clearly advantageous: the significantly greater interior length both with folded seats and with the rear bench upright, as well as the considerably wider opening, make it easier to load long and wide cargo and allow more flexible loading.
Large, flat, or wide items are easier to maneuver and transport in the Grandland.
The SEAT Ibiza, on the other hand, scores with usable depth near the loading area: due to the greater depth between the loading edge and the trunk floor, cargo sits lower in the vehicle in the Ibiza, which can create space especially when stacking taller items directly behind the loading edge.
Together with the lower loading edge of the Ibiza (since the Grandland’s loading edge is 3.5 in higher), this results in a more ergonomic loading process for heavy or bulky items in the Ibiza — less lifting over a high edge.
Practically speaking: those who frequently transport long or wide loads benefit more from the Opel Grandland. Those who value easier lifting and a lower loading edge or often store more compact, taller stacked cargo directly behind the opening will find advantages in the SEAT Ibiza.
Smaller differences such as opening height (+0.4 in) and minimum interior width (+0.8 in) are hardly relevant in everyday use.
