Trunk comparison: Audi Q5 vs Durchschnitt Subcompact

Key Differences (highlighted)
The Audi Q5 offers significantly more cargo length: with the seats folded down, the trunk of the Q5 is +15 in (+30%) longer, and with the first row upright, it is even +12.6 in (+51%) longer than the average subcompact.
Additionally, the Q5 has a considerably wider opening: the width of the trunk opening is +8.7 in (+24%) larger, making it easier to maneuver wider items in and out.
In contrast, the subcompact has a much deeper vertical offset between the loading edge and the trunk floor: the depth (loading edge to trunk floor) is +4.3 in (+138%) greater, meaning the interior forms a significantly deeper well there.
Implications for Usability
Longer cargo: Due to the significantly longer interior dimensions (both with folded seats and upright rear bench), the Audi Q5 is much better suited for long items like furniture parts, skis, or longer boxes.
The larger opening width enhances this advantage because wide or bulky cargo fits more easily through the rear opening.
Tall/deep cargo: The average subcompact scores with a notably deeper trunk well below the loading edge. This can be advantageous when items need to stand upright under the loading edge or when you want to "sink" luggage to optimize forward visibility or trunk lid height.
At the same time, a deep well can make lifting/setting down heavy objects less convenient because more vertical offset must be overcome.
Practical summary: For regularly transporting long or wide items, the Audi Q5 is clearly superior. The subcompact, on the other hand, offers advantages with deep, tall, or "sinkable" cargo due to the deeper trunk well but feels noticeably limited in length and opening width.
Smaller differences like opening height (+3%), loading edge height (+1%), or narrowest width (+5%) are hardly noticeable in everyday use.
