Trunk comparison: BMW X3 vs Dacia Duster

Key Differences
Two values stand out clearly in the comparison: the significantly greater trunk depth of the Dacia Duster (+3.1 in, stated as +700%) and the larger width of the trunk opening in the BMW X3 (+5.5 in, 14%). These two differences have the strongest impact on practical use.
Other deviations include: the BMW X3 offers slightly more length with the seats folded down (+5.5 in, 9%), the Dacia Duster is minimally longer with the first row of seats upright (+0.8 in, 2%), the trunk opening of the Duster is slightly higher (+0.8 in, 3%), and its loading edge is somewhat higher above the ground (+2.4 in, 9%).
The narrowest width inside the trunk is 3.9 in (10%) larger in the BMW X3.
Impact on Usability
The much greater depth in the Dacia Duster practically means a significantly deeper “trunk floor” relative to the loading edge.
This creates more vertical space inside behind the loading edge but can make loading heavy items more difficult because the loading edge is higher and objects must be lifted or lowered further down.
Together with the 2.4 in higher loading edge, the Duster’s design is less comfortable for frequent lifting of heavy loads but better suited for storing tall or irregularly shaped items inside the trunk space.
The wider trunk opening of the BMW X3 makes loading and unloading bulky, wide items much easier – furniture, large boxes, or wide sports equipment can be maneuvered more easily sideways through the opening. The slightly greater narrow interior width of the X3 also supports loading wider items.
Because the X3’s loading edge is lower, handling heavy loads is overall more ergonomic than in the Duster. Additionally, the X3 offers more cargo length with the seats folded down, making it more practical when transporting long items.
In summary: Those who frequently load wide or very bulky items and prefer ergonomic loading and unloading will benefit more from the BMW X3. Those who need more vertical interior space (e.g., for tall items in the trunk) and accept the higher loading edge will find advantages in the Dacia Duster.
