Trunk comparison: Jeep Compass vs Mercedes Benz GLE

Main Differences
In terms of usable length, the Mercedes-Benz GLE has clear advantages: with the seats folded down, its cargo area is 11.4 in (≈18%) longer, and with the first row of seats upright, it is 9.1 in (≈28%) longer than the Jeep Compass.
The Jeep Compass, on the other hand, scores points with interior depth: the distance from the loading edge to the trunk floor is 6.3 in (≈1500%) greater in the Compass, and the height of the trunk opening in the Compass is also 1.6 in (≈5%) higher.
The loading edge height is the same for both models. Width and opening width favor the GLE (+3.1 in and +2.8 in respectively), but these differences are each under 10%.
Impact on Usability
The longer cargo areas of the GLE make it better suited for long items (e.g., skis, slats, long furniture parts) and for transporting larger, lengthwise-oriented luggage, especially when the rear seats are folded down.
The Compass is practically usable in a different way due to its significantly greater interior depth: the deeper trunk well offers more storage space below the loading edge and more effective height in the cargo area, which helps when storing tall or irregularly shaped items and allows luggage to be stored "deeper" without stacking upwards.
The slightly higher trunk opening of the Compass marginally facilitates sliding through tall items, and the same loading edge height of both cars means similar effort when lifting over the edge.
The wider spots and larger opening width of the GLE are present but comparatively minor and only slightly affect practical use.
