Trunk comparison: BMW X3 vs Mercedes Benz GLE

Key Differences

Most important difference: The trunk of the Mercedes-Benz GLE is 3.9 in longer (+11%) with the first row of seats upright than that of the BMW X3. With the seats folded down, the GLE is also longer, but only by 6.3 in (+9%).

The height of the trunk opening is +0.8 in (+3%) greater on the GLE, while the loading edge of the GLE is +2.8 in (+10%) higher above the ground.

The depth (loading edge to trunk floor) is the same. The BMW X3 offers +2 in (≈5%) more width at the narrowest point and +0.8 in (≈2%) more width at the trunk opening than the GLE.

Impact on Usability

The significantly longer cargo space of the GLE with the rear seats upright (+11%) makes it better suited for long items that need to be transported without folding down the rear seats (e.g., skis, long shipments, more luggage with full seating).

The slightly larger opening height (+0.8 in) also helps with sliding in taller cargo, but only marginally.

The higher loading edge of the GLE (+2.8 in) makes lifting heavy or bulky loads into the trunk more difficult compared to the X3; this makes loading more strenuous for individual persons.

Since the trunk depth is the same, the X3 and GLE balance out in available length depth once the loading edge is taken into account.

The BMW X3 scores on width: more space at the narrowest point (+2 in) and a slightly wider opening (+0.8 in) make it easier to load wide or bulky items (e.g., boxes, furniture parts). Those who frequently transport wide but not very long cargo or value easier maneuvering of large packages have advantages in the X3.

In short: GLE = better for longer cargo with full occupancy; X3 = more practical for wide or easier-to-lift cargo. The choice depends on typical cargo.
