Trunk comparison: BMW X3 vs Jeep Compass

Highlighted Differences (>10%)
In the comparison, it is particularly noticeable: With the first row of seats upright, the trunk of the BMW X3 is 5.1 in (16%) longer than that of the Jeep Compass.
The narrowest point in the loading area is 5.1 in (13%) wider in the BMW X3 than in the Compass. Conversely, the Jeep Compass has a significantly greater depth between the loading edge and the trunk floor: it is 6.3 in (1500%) deeper here than the BMW X3.
Impact on Usability
These differences lead to clearly different strengths in everyday use: The BMW X3 offers more usable loading length and more width at the narrowest point with the rear seat upright.
This makes it more practical for longer or wider items (e.g., longer boxes, skis, furniture parts) that do not extend over the entire depth of the trunk and where the narrowing could otherwise become a problem.
The Jeep Compass, on the other hand, has a significantly deeper cargo space below the loading edge. This creates room for bulky, voluminous, or tall loads that can be recessed into an interior recess (e.g., crates, larger shopping loads) and better hides cargo from view.
However, this depth comes with a higher loading edge and an overall narrower width at the narrowest point, which can make lifting heavy items into the trunk more difficult and limit fitting very wide parts.
In short: BMW X3 = better for elongated and wider cargo with easier loading; Jeep Compass = better for voluminous cargo stored in depth, but with a higher loading edge and restricted width at the narrowest point.
