Trunk comparison: BMW i4 vs Dacia Duster
Key Differences
There are several relevant differences in the trunk dimensions: The height of the trunk opening in the Dacia Duster is 5.5 in (21%) higher than in the BMW i4. The depth of the trunk (loading edge to trunk floor) is 0.8 in (25%) greater in the BMW i4. The width of the trunk at its narrowest point is 4.7 in (14%) greater in the Dacia Duster.
Smaller differences include: the BMW i4 offers 4.7 in (7%) more loading length with the seats folded down and 0.4 in (1%) more length with the first row of seats upright than the Duster.
The width of the trunk opening is 1.6 in (4%) larger in the Duster, and the loading edge in the Duster is 2.4 in (9%) higher above the ground than in the BMW.
Implications for Usability
The significantly higher trunk opening of the Duster makes it easier to load tall items (e.g., furniture, tall boxes, plants) and reduces the risk of bumping into the opening—practical when transporting bulky, tall cargo.
At the same time, the narrower interior width of the BMW (at the narrowest point) is a disadvantage for wide items: the Duster can accommodate about 14% wider cargo at its narrowest point, allowing wide boxes or furniture to be loaded more easily without angling.
The greater depth between the loading edge and trunk floor in the BMW means more usable interior height or a lower cargo volume beneath the loading edge.
This helps when items need to be placed deeper inside the vehicle (e.g., stacked boxes), and combined with the lower loading edge of the BMW (compared to the Duster), it results in a more ergonomic access when lifting heavy loads.
Although the loading edge in the Duster is higher, the significantly larger opening height compensates when loading tall items but can make lifting heavy objects from the ground somewhat more strenuous.
The slightly longer loading length of the BMW with folded seats (+4.7 in, 7%) is advantageous for very long items (e.g., boards, skis), but overall has less impact than the mentioned >10% differences.
The slightly larger opening width of the Duster (+1.6 in) is minimal and has little practical effect compared to the more noticeable interior width difference.
Conclusion: For very tall cargo and wider items, the Dacia Duster is more practical for everyday use. For ergonomic loading and unloading of heavy loads, somewhat more interior height below the loading edge, and when longer cargo space is needed (folded seats), the BMW i4 offers advantages.
