Trunk comparison: Peugeot 308 SW 3-row vs Seat Ibiza

Key Differences
The Peugeot offers a significantly longer cargo space with the front seats upright: +15.7 in (59%) compared to the Ibiza. In contrast, the SEAT Ibiza has more trunk space with all seats fully upright: +13 in (94%) compared to the Peugeot.
The depth of the trunk (distance from loading edge → trunk floor) is +5.9 in (375%) greater in the Ibiza, and the loading edge itself is +5.1 in (23%) higher above the ground in the Ibiza.
In favor of the Peugeot, the width of the trunk opening is significantly larger: +9.8 in (28%). Smaller differences (e.g., +1.6 in / 3% with folded seats, +2.8 in / 9% opening height, +0.8 in / 2% narrowest width) are not highlighted here.
Impact on Usability
- Peugeot 308 SW (3-row): The significantly greater loading length with the front seats upright and the wider opening make it easier to store long and wide items without adjusting or moving the front seats.
This makes the vehicle more practical for bulky/large cargo and for users who frequently transport long parts or wide luggage. The lower loading edge (not drastically different, but ergonomically better) makes lifting heavy loads easier.
- SEAT Ibiza: When all seats are in use, the Ibiza offers considerably more trunk length, thus more usable space with full seating — practical for trips with many passengers where luggage still needs to be carried.
The greater depth of the trunk (deeper floor area) increases volume but can make loading bulky or heavy items more difficult because they must be lowered deeper. The +5.1 in higher loading edge also worsens ergonomics when lifting heavy luggage (more effort required).
In summary: Peugeot is advantageous for flexible, bulky, or wide cargo and for easier loading and unloading; SEAT Ibiza offers more luggage space with full seating but has a higher loading edge and deeper cargo floor, which complicates handling heavy or bulky loads.
