Trunk comparison: Audi A4 Avant vs Audi Q5

Key Data (from the comparison)

Essential dimensions at a glance: The Audi A4 Avant offers slightly more loading length with the seats folded down (+6.7 in / 10%) and a longer loading surface with the first row of seats upright (+3.9 in / 11%) than the Q5. The trunk opening of the A4 is somewhat higher (+2.4 in / 8%).

The Audi Q5 has advantages in other areas: it has a significantly greater trunk depth (loading edge → trunk floor) (+1.2 in / ≈60%), the loading edge is higher above the road (+4.3 in / ≈17%), and the trunk opening is wider (+4.3 in / ≈11%).

The narrowest width in the trunk is only slightly larger in the Q5 (+1.6 in / 4%).

How this affects practical use

Audi A4 Avant — better suited for long, lower loads: The longer loading surface (especially with the first row of seats upright) makes the A4 Avant more suitable for long items such as skis, slats, or furniture parts that cannot be loaded crosswise.

The slightly higher trunk opening facilitates loading tall objects vertically. Overall, loading heavy, long goods is easier because the loading edge is lower (the Q5 is significantly higher here).

Audi Q5 — better suited for wide and bulky loads: The wider trunk opening (+4.3 in) and the significantly greater depth between loading edge and trunk floor (≈60% more) make the Q5 more practical for wide or bulky items that require floor space.

The larger opening allows easier maneuvering of bulky or irregularly shaped parts. However, the loading edge in the Q5 is significantly higher (+4.3 in), which makes lifting heavy loads more difficult.

Conclusion: Those who often transport long, flat items and prefer easy access will likely have advantages with the A4 Avant. Those who need more width and deep interior space for bulky or irregularly shaped cargo will benefit more from the Q5 — albeit at the cost of a higher loading edge that complicates lifting.
