Trunk comparison: Hyundai IONIQ vs Mercedes Benz GLE

Key Differences (≥10%)

Length with seats folded down: The GLE offers +12.2 in (19%) more cargo length than the IONIQ.
Length with front row upright: The GLE is +5.5 in (15%) longer in trunk space with the rear seat upright.
Height of the trunk opening: The GLE's opening is +5.9 in (23%) higher than the IONIQ's.
Depth of the trunk (loading edge → trunk floor): The IONIQ has a +4.7 in greater depth; the stated relative figure of 1100% indicates a very large relative difference (likely due to a very small reference value).
Width of the trunk opening: The GLE's opening is +6.3 in (17%) wider than the IONIQ's.

Impact on Usability

The GLE is clearly better suited for long and bulky loads: the greater usable length both with folded and upright rear seats allows transporting longer items (e.g., furniture, skis, long boxes) without awkward angling.

The significantly higher and wider trunk opening makes loading large, tall, or wide parts easier — fewer edge and angle issues when maneuvering.

The IONIQ scores with the greater depth between the loading edge and trunk floor. This means more "recess" in the trunk, allowing smaller or stackable items to lie more securely and more volume to be accommodated with the same external dimensions.

However, this deep well can make lifting heavy items more difficult because the weight must be lifted or pulled further down.

Specifically: For regular transport of long or very wide items, the GLE is the more practical choice. If it is more about secure storage and a deeper loading well for stored items, the IONIQ can offer advantages.

Smaller Differences (<10%)

The loading edge of the GLE is only +1.2 in (4%) higher above the road — this difference is minor and hardly affects everyday usability. The narrowest width in the trunk differs by only +2 in (5%) as well.
