Trunk comparison: BMW 3 Series Touring vs Seat Ibiza

Key Differences and Their Impact on Usability

The BMW 3 Series Touring offers significantly more cargo length: with the seats folded down, the trunk is 13.4 in (24%) longer, and with the rear seat upright, even 12.6 in (47%) longer than the SEAT Ibiza.

Additionally, the width of the trunk opening on the BMW is 4.7 in (14%) larger, which makes loading wider items easier.

In contrast, the SEAT Ibiza has several features with advantages in the vertical dimension: the height of the trunk opening is 3.9 in (14%) higher, the depth between the loading edge and the trunk floor is 7.1 in (1800%) higher, and the loading edge itself is 3.5 in (15%) higher above the road than on the BMW.

The width at the narrowest point is only slightly larger on the Ibiza (+1.6 in / 4%) and thus not a significant difference.

Practical consequences: For long and wide items (e.g., furniture, long boxes, skis), the BMW is clearly advantageous: the greater length and wider opening facilitate transport and loading, and the lower loading edge makes lifting heavy loads easier.

The SEAT Ibiza offers more vertical space and a higher opening, which is beneficial when transporting bulky, tall items or high stacks; however, the higher loading edge makes loading heavy items more strenuous.

In short: BMW is better for long/wide loads and more comfortable lifting, Ibiza is better when additional height/vertical cargo space is needed—at the expense of more ergonomic loading.
