Trunk comparison: Audi Q3 vs Mercedes Benz GLE

Core Differences (highlighted: >10%) and Practical Implications

The Mercedes‑Benz GLE offers significantly more loading length: With the seats folded down, the trunk of the GLE is +11 in (+17%) longer, and with the first row upright, it is +5.9 in (+17%) longer than the Audi Q3. Practically, this means the GLE can transport longer items (e.g., furniture parts, long sports equipment like skis, or bulky poles) without repositioning and overall provides a much more flexible cargo space profile for longer loads.

For users who frequently transport long or bulky items, the GLE is noticeably more practical.

The Audi Q3, on the other hand, has a significantly greater trunk "depth" in terms of the distance from the loading edge to the trunk floor: +3.5 in (800%) compared to the GLE.

This creates a deeper cargo "well": advantageous for securely storing loose or lower items (they sit deeper and shift less) and for hiding luggage under a flat loading surface.

The downside is that heavy or large cargo must be lifted deeper, and reaching into the lower area can be less comfortable; additionally, a deep well reduces usable height with the tailgate standing upright.

In short: The GLE is better suited for long, flat, or bulky loads thanks to significantly greater loading length; the Q3 offers advantages in securing smaller/loose items and concealed storage due to the deeper cargo well but is less practical for heavy lifting or very long items.

Note on Smaller Deviations

Other differences such as trunk opening (+1.2 in), loading edge height (+0.8 in), or width differences (+2–2 in) are under 10% and have less impact on everyday use — they may slightly affect loading ease or the width of the loading opening but are secondary compared to the effects mentioned above.
