Trunk comparison: Citroen C3 vs Dacia Jogger

Key Differences (all >10%)
The Dacia Jogger offers significantly more cargo space in length: with the seats folded down, the trunk is 16.9 in (32%) longer, and with the first row of seats upright, it is even 19.3 in (73%) longer than in the Citroën C3. The Jogger's trunk opening is 5.1 in (16%) higher and 9.8 in (26%) wider at its narrowest point; the overall width of the opening is 5.9 in (17%) greater than that of the C3. The Citroën C3, on the other hand, has a significantly greater depth between the loading edge and the trunk floor (+5.9 in, 188%), and its loading edge sits 4.7 in (18%) higher above the ground than the Jogger's.
Impact on Usability
For long and wide cargo, the Jogger is clearly advantageous: the greater interior length with seats folded or upright, as well as the wider narrow point and larger opening, make it easier to accommodate furniture, bicycles, or bulky boxes.
The higher opening also reduces the risk of hitting the ceiling when lifting items in.
The Jogger's lower load floor and lower loading edge make lifting heavy items easier—shorter leverage arms and less effort when loading. This makes the Jogger more practical for families, moves, or tradespeople who regularly need to transport large or bulky cargo.
The C3 scores with a deeper trunk floor below the loading edge.
This creates a deeper "cargo area" beneath the loading edge, which can be useful for securely storing flat or stackable items and allows luggage to sit somewhat "recessed." However, the higher loading edge makes loading heavy, bulky loads more cumbersome; in return, the C3 is overall more compact and better suited for city use with occasional cargo transport.
In short: Those who often transport wide, long, or tall cargo and appreciate easy loading are better served by the Dacia Jogger. Those who mainly drive in the city and only occasionally transport luggage or smaller items will find a more compact solution with a deeper, more protected cargo area in the Citroën C3.
