Trunk comparison: Jeep Avenger Electric vs Peugeot 308 SW 3-row

Key Differences
Peugeot +16.1 in (61%) trunk length with front seats upright — the 308 SW offers significantly more cargo space when the front row is in the normal position. Jeep +12.6 in (91%) trunk length with all seats upright — the Avenger has significantly more usable space when all rows are in use. Peugeot +3.9 in (13%) higher trunk opening — the opening dimension at the top is noticeably larger. Jeep +2.8 in (175%) deeper trunk well (loading edge → trunk floor) — the Avenger has a significantly deeper cargo well. Jeep +6.3 in (29%) higher loading edge above the road — the Avenger’s loading edge is noticeably higher. Peugeot +4.3 in (12%) wider narrow trunk width and +5.5 in (14%) wider opening width — the 308 SW is wider inside and at the opening.
Implications for Usability
Space with full occupancy: Because the Avenger offers significantly more cargo length with all seats upright, it is more practical when all seats are regularly used and luggage still needs to be transported (e.g., families fully occupied plus suitcases).
Flexibility and large items: The Peugeot scores when seats are folded or certain seat configurations are used — significantly more length with front seats upright as well as larger opening and interior widths make it better suited for bulky or wide cargo (furniture, large boxes, sports equipment).
Loading and unloading: The higher loading edge of the Jeep (+6.3 in) makes lifting heavy items more difficult; at the same time, the deeper cargo well in the Avenger provides more space below the loading edge, which secures smaller items better.
The Peugeot has the more practical, lower loading edge for easier loading and unloading.
Loading height and cargo height: The higher opening on the Peugeot (+3.9 in) makes it easier to store tall items through the rear opening. Combined with the wider opening width, the 308 SW is overall more favorable for tall and wide cargo.
Short-term recommendation: If you often travel fully occupied with luggage, the Jeep Avenger is more practical. If you more frequently transport bulky, wide, or tall cargo or prefer easier loading and unloading, the Peugeot 308 SW is the better choice.
