Trunk comparison: Seat Ibiza vs VW Golf Wagon

Core Differences (highlighted: >10%)
The VW Golf Wagon offers significantly more cargo length: +18.1 in (≈33%) with seats folded down and +16.1 in (≈60%) with the first row upright compared to the Seat Ibiza. The trunk opening of the Golf Wagon is also wider: +4.7 in (≈14%).
Two dimensions are notably larger in the Seat Ibiza: the trunk depth (distance from loading edge → trunk floor) is +3.1 in (≈73%) greater, and the loading edge is +3.1 in (≈13%) higher above the road than in the Golf Wagon.
What impact do these differences have on usability?
More cargo length and a larger opening in the VW Golf Wagon specifically mean: longer items (e.g., furniture, skis, building materials) can be transported much more easily; with seats folded down, there is noticeably more cargo volume.
The wider trunk opening facilitates loading and unloading bulky or wider loads and increases practicality when fully loaded.
In the Seat Ibiza, the greater trunk depth results in a more recessed cargo floor behind the loading edge, which can create more usable space below the loading edge (e.g., for flat-lying luggage or lower boxes).
However, the higher loading edge makes lifting heavy items in more strenuous and increases the load when lifting.
In practice, this means: for frequent loading of heavy or tall loads, the Golf Wagon is more comfortable; for low and deep-stored cargo, the Ibiza can offer advantages due to the deeper cargo floor, provided loading over the higher loading edge is not inconvenient.
Dimensions that differ only slightly (e.g., trunk opening height +5% in the Ibiza or narrowest width +2% in the Golf) usually play a minor role in everyday use compared to the differences mentioned above.
