Trunk comparison: Audi A6 Sedan vs Audi Q5

Key Differences

The Audi A6 offers significantly more cargo length: with the seats folded down, the trunk is 11.4 in (17%) longer and with the front row upright, 7.9 in (21%) longer than the Audi Q5. The depth of the A6 (loading edge to trunk floor) is also greater: plus 1.6 in (50%).

In contrast, the Audi Q5 has a significantly higher trunk opening: plus 11.4 in (58%), a higher loading edge to the road: plus 3.1 in (12%), and a wider trunk opening: plus 7.5 in (20%) than the A6. The width at the narrowest point differs hardly at all (+0.4 in / 1%).

Impact on Usability

The longer and deeper cargo areas of the A6 make it more practical for long and flat items (e.g., furniture parts, slats, skis, long boxes) as well as for larger overall loads with the seats folded down. The lower loading edge of the A6 also makes it easier to lift heavy items into the vehicle.

The Q5 scores with bulky, wide, or tall cargo: The significantly higher and wider opening facilitates loading bulky objects and maneuvering while loading.

However, the higher loading edge requires more lifting force when loading heavy loads and can pose limitations when loading and unloading from low sidewalks or in low garages.

In short: Those who often transport long or heavy goods and prefer a low loading height are better served by the A6. Those who more frequently load wide or tall, bulky items and benefit from a larger opening have the practical advantage with the Q5.
