Trunk comparison: BMW X4 vs Jeep Compass

Key Differences (>10%)
The most significant differences concern the usable cargo volume and vertical usability: The BMW X4 offers a trunk that is 7.9 in (24%) longer with the first row of seats upright compared to the Jeep Compass, giving it a clear advantage for longer, flat-lying loads.
The Jeep Compass, on the other hand, has a trunk opening that is 5.9 in (21%) higher and a depth measured from the loading edge to the trunk floor that is 3.1 in (100%) greater, providing significantly more vertical space and a deeper cargo floor.
Impact on Usability
For long, flat items (e.g., skis, long boxes, furniture panels), the BMW X4 is the more practical choice because the longer cargo area with seats upright allows for more usable lengthwise depth.
Those who frequently load bulky, tall, or voluminous items (e.g., moving boxes, crates, equipment) benefit from the Jeep Compass: the higher opening makes it easier to lift tall parts in, and the greater depth creates more space below the loading edge, allowing items to be better "recessed" and the available interior space to be better utilized.
Smaller differences, such as the BMW X4's 0.8 in higher loading edge (easier lifting vs. easier maneuvering) and the 3% wider narrowest point in the BMW as well as the identical width of the opening in both models, have only minor practical effects in everyday use and do not change the fundamental usage profiles.
