Trunk comparison: BMW X4 vs Dacia Duster

Key Differences

The measurable differences are overall small; only the height of the trunk opening differs significantly. The trunk opening of the Dacia Duster is 4.3 in (16%) higher than that of the BMW X4. Other comparison values: BMW X4 has +3.1 in (5%) more usable length with folded seats and +2 in (5%) more length with the first row of seats upright.

The width of the opening is +2 in (5%) larger on the BMW. Depth (loading edge → trunk floor) and narrowest width are the same for both models. The loading edge of the BMW is +1.2 in (4%) higher above the road.

Impact on Usability

The significantly higher trunk opening of the Duster makes loading tall or bulky items easier: items can stand upright or be guided more easily through the opening, which is especially noticeable when transporting furniture, boxes, or tall sports equipment.

The BMW offers slightly more usable length (about 5% each), which gives it a slight advantage for longer items like poles, skis, or flat furniture. This advantage is moderate — it only affects everyday usability with really long loads.

The lower loading edge of the Duster slightly eases lifting heavy loads compared to the BMW; however, the difference is small. The somewhat larger width of the BMW opening (≈5%) also offers only a small advantage when fitting wider items.

Conclusion: For tall, bulky cargo, the Dacia Duster is more practical due to the 16% higher opening. For longer cargo, the BMW X4 has a slight advantage thanks to the greater usable length; otherwise, the differences in everyday use are rather minor.
