Trunk comparison: Audi A4 Avant vs Mercedes Benz GLE
Key Differences
The two most noticeable, percentage-relevant differences concern the depth of the trunk and the loading height: The depth (distance from loading edge → trunk floor) of the Audi A4 Avant is +2 in (≈400%) greater than that of the Mercedes-Benz GLE.
The loading edge of the GLE is +5.5 in (22%) higher above the road than that of the A4 Avant.
All other mentioned differences (length with folded seats +4.3 in/6%, same length with upright first row of seats, height of the trunk opening +1.6 in/5% in favor of Audi, width at the narrowest point +2.4 in/6%, and opening width +3.1 in/8% in favor of GLE) are under 10% and thus less pronounced.
Impact on Usability
The significantly greater depth in the A4 Avant practically means: the trunk floor sits lower relative to the loading edge, creating more usable interior height directly behind the loading edge.
This facilitates storing bulky or tall items that are to be placed immediately behind the loading edge and allows somewhat better stowing of smaller luggage pieces beneath the loading edge.
Combined with the significantly lower loading edge, loading and unloading heavy or bulky items in the A4 Avant is overall more ergonomic and less strenuous.
The higher loading edge height of the GLE (+5.5 in) means that cargo must be lifted higher when loading — which is noticeably less favorable for heavy or large items.
However, the GLE offers slightly more interior length with folded seats (+4.3 in) as well as a marginally greater width at the narrowest point and at the opening; this tends to make it better suited for very long or wider cargo, even though these differences are percentage-wise under 10%.
Conclusion: For frequent, low-effort loading with suitcases, groceries, or bulky but not extremely long items, the Audi A4 Avant is overall more practical due to the deeper loading floor and lower loading edge.
If very long or especially wide parts need to be transported regularly, the somewhat greater folded loading length and opening width of the GLE speak in its favor — though the higher effort required for lifting should be taken into account.
