Trunk comparison: Mercedes Benz GLB vs Mercedes Benz GLE

Key Differences

The models mainly differ in cargo volume, access, and loading edge:

• With the first row of seats upright, the GLE's trunk is 3.9 in (11%) longer than the GLB's.
• With the seats folded down, the GLE is 6.7 in (10%) longer — just at the 10% mark, so not highlighted as >10%.
• The depth of the trunk (distance from loading edge to trunk floor) of the GLB is 4.7 in (1100%) greater than the GLE's — a very large difference.
• The width at the narrowest point is the same; the GLE's trunk opening is only slightly wider (+1.6 in / 4%).
• The GLB's trunk opening is 2.8 in (9%) higher than the GLE's; the GLE's loading edge is 2 in (7%) higher above the ground than the GLB's.

Impact on Usability

GLE — advantages in length and long cargo:

• The longer load floor (especially with the first row upright) makes the GLE better suited for long items (skis, long packages, furniture parts) without folding seats.
• Even with seats folded down, the GLE offers slightly more cargo area, which helps with bulky or flat loads.

GLB — advantages in height, depth, and easy loading/unloading:

• The significantly greater depth of the GLB means a lower trunk floor behind the loading edge. This creates more usable storage volume in the lower area and can reduce shifting of small luggage into a kind of cargo tub.
• The higher trunk opening of the GLB makes loading tall items easier, and the lower loading edge compared to the GLE reduces the effort needed to lift heavy loads.

Conclusion

Those who need to transport longer items or often require maximum loading length benefit more from the GLE.

Those who want more practically usable volume in the lower area, a higher opening, and easier lifting — i.e., frequent loading and unloading of boxes, shopping, or bulky, tall items — are better served by the GLB.
