Trunk comparison: BMW X3 vs VW Polo

Key Differences

The BMW X3 offers significantly more cargo space: with the seats folded down, the trunk of the X3 is 15.7 in (29 %) longer and with the first row upright, 11.4 in (44 %) longer than the VW Polo.

The trunk opening of the X3 is also larger: the opening height is +3.9 in (14 %) and the opening width is 7.9 in (22 %) wider than the Polo.

Another notable difference is the trunk depth (loading edge to trunk floor): the VW Polo is 3.1 in (700 %) deeper than the X3 here. The loading edge height is the same for both models; the narrowest width in the trunk differs by only 3.1 in (8 %), which is below the 10% threshold.

Impact on Usability

For long or bulky items (skis, furniture parts, large boxes), the BMW X3 clearly has the advantage: the longer loading dimensions with folded seats and upright first row, as well as the larger opening, make loading easier and allow for larger cargo dimensions.

The higher opening of the X3 simplifies lifting tall items and reduces the risk of hitting the roof edge. The wider opening makes maneuvering wide loads significantly easier.

The deeper trunk floor in the VW Polo means more usable vertical volume below the loading edge, which can be advantageous for bulky but not particularly long items.

At the same time, the loading edge remains at the same height as in the X3, so lifting heavy items from the ground is similarly demanding. Due to the shorter length and narrower opening, the Polo is less suitable for long or very wide loads; it benefits more from compact, tall cargo.

In short: Those who regularly transport long or wide loads benefit from the BMW X3; those who mainly rely on compact volume for shorter, taller luggage can find sufficient storage space in the Polo. The identical loading edge heights mean comparable physical effort when loading/unloading in both models.
