Trunk comparison: BMW 3 Series Touring vs BMW X5

Key Differences

Looking at the trunk dimensions, three differences stand out clearly: The trunk opening of the BMW X5 is 3.1 in larger (+11%), the narrowest width in the X5's trunk is 5.9 in wider (+16%), and the loading edge of the X5 is 7.5 in higher (+32%) than that of the 3 Series Touring.

Other differences such as the slightly longer overall trunk length with the seats folded down (+6%) or with the first row upright (+4%) exist but are under 10%. The depth (loading edge to trunk floor) is the same in both models.

Impact on Usability

The greater opening height (+11%) and the wider narrowest point (+16%) make the X5 significantly more practical for bulky and tall items: bulky boxes, bicycles (partially), strollers, or tall cartons can be loaded and unloaded more easily since less maneuvering is required and wider loads are less likely to get stuck at tight spots.

On the other hand, the significantly higher loading edge of the X5 (+32%) reduces everyday usability when lifting heavy loads. Heavy groceries, boxes, or furniture must be lifted higher in the X5, making loading and unloading more strenuous.

For people who frequently load heavy items or want to load the vehicle without assistance, the lower loading edge of the 3 Series Touring is more ergonomic.

In practice, this means: Those who often transport bulky or tall items and rely on maximum width and opening (e.g., outdoor gear, building materials, tall cartons) benefit from the X5. Those who frequently carry heavy but relatively flat loads or regular everyday groceries and value easy lifting have an advantage with the 3 Series Touring.

Smaller length differences (<10%) play only a minor role in most everyday cases.
