Trunk comparison: BMW X3 vs Opel Corsa

Key Differences and Impact on Usability
The comparison reveals several clear differences: The BMW X3 offers a trunk that is 18.1 in (35%) longer with the seats folded down and a cargo length that is 11.4 in (44%) longer with the first row of seats upright than the Opel Corsa.
Additionally, the trunk width at the narrowest point in the X3 is 5.5 in (15%) larger and the width of the trunk opening is 10.2 in (30%) larger than in the Corsa.
The Opel Corsa, on the other hand, has a significantly deeper cargo well: the depth (loading edge to trunk floor) is 7.1 in (1700%) greater than in the X3. The height of the trunk opening differs by only 2.4 in (8%) and is therefore not significant.
In practical terms, this means: The BMW X3 is clearly better suited for longer and wider cargo — long items, wide boxes, or bulky luggage can be loaded more easily and fit better in the trunk even with the seats upright.
The larger opening facilitates maneuvering bulky parts during loading. The Opel Corsa scores with its deeper cargo well: items can be recessed further down, which increases the volume for taller cargo in the loading area and may provide more space for standing, tall objects.
At the same time, the deeper cargo floor can make lifting heavy items in and out more difficult. Since the loading edge height is the same for both models and the opening height differs only slightly, the effort required to load between the vehicles is practically comparable in this regard.
