Trunk comparison: Audi A6 Sedan vs Ford S-MAX

Key Differences

The Ford S‑Max stands out most clearly in the size of the trunk opening: it is 16.9 in (86%) taller and the opening width is 4.7 in (13%) wider than the Audi A6. This makes the S‑Max significantly more practical for loading tall or bulky items (e.g., furniture, upright strollers, or bulky cargo) because more height and width are available, making maneuvering when lifting and sliding items in easier.

The Audi A6 excels in depth and loading edge height: the depth (loading edge → trunk floor) is 3.5 in (300%) greater and the loading edge itself is 3.5 in (16%) higher above the road than in the S‑Max.

Greater depth means more usable volume lengthwise and better options for storing long or flat items. However, the higher loading edge requires more effort when lifting heavy loads and can make loading bulky, heavy items less practical.

Smaller Differences

Regarding lengths and narrowest width, the differences are minor: with seats folded down, the S‑Max is 1.2 in (2%) longer, while with the first row upright, the Audi A6 is 1.2 in (3%) longer.

The narrowest trunk width differs by only 0.4 in (1%) in favor of the S‑Max. These differences are so small that they have hardly noticeable effects in everyday use.

Conclusion

For regularly transporting tall or wide items, the Ford S‑Max is the more practical choice due to the significantly larger opening in height and width.

For users who value more usable depth (longer or flatter cargo), the Audi A6 offers advantages but at the cost of a higher loading edge, which makes lifting heavy items more difficult. Small length and width differences are negligible.
