Trunk comparison: Audi A6 Sedan vs Mazda Mazda CX-5

Key Differences

The Audi A6 offers a significantly longer cargo length: when all seats are folded down, the trunk of the A6 is 9.8 in (15%) longer, and with the first row upright, 7.5 in (20%) longer than in the Mazda CX‑5. The trunk depth (distance from loading edge to trunk floor) is 2.8 in (140%) greater in the Audi.

In contrast, the Mazda CX‑5 has a higher and wider opening: the height of the trunk opening is 11.4 in (58%) higher and the width of the opening 4.7 in (13%) wider than in the Audi.

Additionally, the loading edge of the Mazda is 3.9 in (15%) higher above the ground. The narrowest width inside the trunk differs only slightly (+1.2 in / 3%) and is therefore negligible.

Impact on Usability

For long items (e.g., slats, skis, furniture parts), the Audi A6 clearly has the advantage: the greater cargo length and depth provide more usable interior length and volume, allowing longer parts to fit without complicated stowing.

For very tall or bulky items (e.g., tall boxes, larger furniture parts), the Mazda CX‑5 is more advantageous: the significantly higher and wider trunk opening makes it easier to load large, bulky parts that otherwise would not fit due to a narrow opening.

Loading comfort shows contrasts: the loading edge of the Mazda is 3.9 in higher, making lifting heavy items into the trunk more strenuous.

The Audi has a lower loading edge, which facilitates loading heavy loads. The greater depth in the Audi can also mean more frequent reaching into the cargo area when stowing, but offers more storage space.

Practical conclusion: Those who frequently transport long items or value larger, deeper usable volume are better served by the Audi A6. Those who more often have bulky, tall, or wide objects to load and rely on pass-through access benefit from the Mazda CX‑5 despite the higher loading edge.
