Trunk comparison: Audi A6 Avant vs Audi Q5

Key Differences

The biggest differences mainly concern the cargo length and loading geometry.

The Audi A6 Avant offers significantly more cargo length: with the seats folded down, the trunk is 11.8 in (+18%) longer, and with the first row of seats upright, it is 8.7 in (+23%) longer than in the Audi Q5. In contrast, the Q5 has greater loading height and depth values: the depth of the trunk (distance from loading edge to trunk floor) is 2.4 in (+300%) greater and the loading edge is 3.9 in (+16%) higher above the road.

Implications for Usability

More cargo length in the A6 Avant specifically means: longer or flat-loadable items (e.g., slats, furniture parts, skis, long boxes) can be transported more easily. Those who regularly need to carry long loads or flat cargo surfaces clearly benefit from the A6 Avant.

The greater depth and higher loading edge in the Q5 change the handling: the deeper loading well creates a "deeper compartment," providing volume for durable, stackable items, but makes reaching in and out as well as sliding longer cargo sideways less comfortable.

The higher loading edge also means more effort is required when lifting heavy items during loading.

Other, smaller differences (under 10%) — slightly higher opening height in the Q5 (+2.4 in / +8%) as well as somewhat greater widths at the narrowest point (+3%) and at the opening (+9%) — can marginally ease loading wide or bulky parts, but hardly change the fundamental usability compared to the larger differences mentioned above.
