Trunk comparison: BMW i4 vs Skoda Fabia

Key Differences

The BMW i4 offers a loading length that is 13.8 in (25%) longer with the seats folded down than the Škoda Fabia. Even with the front row upright, the i4 is 9.4 in (32%) longer.

However, the Škoda Fabia has a trunk opening that is 5.9 in (22%) higher and a depth between the loading edge and trunk floor that is 3.5 in (90%) greater than the BMW i4.

Smaller differences (under 10%) — such as the i4's loading edge being 0.8 in higher or the Fabia being 5–2.4 in wider at its narrowest points and at the opening — exist but are less impactful.

Impact on Usability

Due to the significantly greater loading lengths, the BMW i4 is better suited when transporting long or lengthwise items (e.g., boards, skis, long furniture parts) or when more usable cargo depth is needed with the seats folded down.

For transports where length and storage volume in the rear area are decisive, the i4 offers a clear advantage.

The Škoda Fabia, on the other hand, scores with accessibility and handling of bulky, rather tall or bulky loads: the higher trunk opening makes it easier to load tall items, and the greater depth between the loading edge and floor creates more internal space behind the loading edge (more usable height in the rear area).

In practice, this means suitcases, large boxes, or bulky, tall items can often be accommodated more easily in the Fabia without hitting the roof edge or the opening frame.

In short: Those who frequently transport long items or need maximum cargo space with folded seats are better served by the BMW i4. Those who often load bulky, tall, or wide items and value easy, ergonomic loading benefit more from the Škoda Fabia.
