Trunk comparison: Citroen C3 vs Peugeot 308 SW 3-row

Key Differences

Clear strengths emerge in cargo volume and cargo geometry for both models: The Peugeot 308 SW is significantly longer with the first row of seats upright (+16.1 in / +61%), and its trunk opening is both higher (+3.9 in / +13%) and noticeably wider (+9.8 in / +28%) than the Citroën C3. The Citroën C3, on the other hand, offers a significantly longer trunk with all seats in place (+12.6 in / +91%) and a much greater trunk depth measured from the loading edge to the floor (+7.5 in / +475%).

Additionally, the C3’s loading edge sits noticeably higher above the road (+8.7 in / +39%).

Smaller differences under 10% are less relevant: When all seats are folded down, the Peugeot has only slightly more length (+3.5 in / 7%), and the narrowest trunk width differs by just +2 in (5%) in favor of the Peugeot.

Impact on Usability

Practically, this means: The Peugeot 308 SW configuration is better suited for loading long or bulky items that benefit from a longer cargo floor with the first row upright.

The higher and significantly wider opening makes loading wide parts (furniture, boxes, bulky containers) easier, and the lower loading edge of the Peugeot facilitates lifting heavy loads into the vehicle.

The Citroën C3 is advantageous in everyday use when the vehicle is fully occupied: With all seats upright, it offers significantly more trunk length, thus more space for luggage or shopping with passengers on board.

The greater trunk depth also means more storage space behind the loading edge (deeper cargo area), but combined with the significantly higher loading edge, it can make handling heavy items more difficult — items must be lifted higher.

In summary: For frequent transport of long or wide, including heavy items, the Peugeot 308 SW is the more practical choice. For more usable luggage volume with full occupancy and a deeper trunk area, the Citroën C3 is better suited, albeit at the cost of a higher loading edge.
