Trunk comparison: Seat Ibiza vs Tesla Model 3

Key Differences

In terms of cargo space, the length of the Tesla stands out: The Tesla Model 3 offers with the seats folded down a cargo area that is 18.1 in (33%) longer than the Seat Ibiza. This makes the Tesla significantly better suited for long items like furniture parts or skis.

Even with the first row of seats upright, the Tesla has a big advantage: the cargo area is 15.4 in (57%) longer, so longer items can often be transported without folding down all the seats.

The Seat Ibiza scores points in the vertical dimension: The height of the trunk opening in the Seat is 11.8 in (58%) greater than in the Tesla — this makes loading tall or bulky items easier and reduces the need to tilt them.

Additionally, the depth of the trunk (loading edge to trunk floor) in the Seat is 3.1 in (73%) greater, which provides more usable volume vertically and facilitates stacking.

Other values with less relevance: The loading edge of the Seat is only 0.8 in (3%) higher, and the narrowest width in the trunk is 1.6 in (4%) larger in the Seat — both have hardly noticeable effects in practice.

The width of the trunk opening is 4.7 in (14%) larger in the Tesla, which together with the longer cargo area makes it easier to load wider items.

Implications for Usability

If you frequently transport long, flat, or wide cargo (skis, slats, larger boxes, furniture parts), the Tesla Model 3 is the more practical choice due to its significantly greater length and wider opening.

For transports where height and stackable volume are more important (straight, tall boxes, stacks of crates, bulky vertically standing items), the Seat Ibiza is better suited thanks to its higher opening and deeper cargo floor.

Smaller differences like the 0.8 in loading edge height or 1.6 in narrowest width hardly affect everyday usability.
