Trunk comparison: Audi A6 Avant vs Kia Sportage

Key Differences

The Audi A6 Avant offers significantly more cargo length: with the seats folded down, the trunk is 10.6 in (≈16%) longer, and with the front seat row upright, the advantage is also 10.6 in (≈30%).

Additionally, the Audi has a deeper usable loading area: the depth (loading edge → trunk floor) is 0.8 in (≈100%) greater.

When loading and unloading, the ratio is reversed in favor of the Audi: the loading edge of the Kia Sportage is 3.1 in (≈13%) higher above the ground.

The width differences at the narrowest point (+1.6 in / 4%) and the opening width (+0.4 in / 1%) are minor; the height of the trunk opening is the same for both models.

Impact on Usability

More cargo length in the A6 Avant means practical advantages when transporting long items (e.g., skis, slats, long packages)—especially relevant when the front seat row remains upright: the Audi accommodates such loads more often without folding seats.

The greater depth gives the A6 more usable volume and allows easier stacking of longer items.

At the same time, the lower loading edge of the Audi makes lifting heavy loads onto the cargo floor level easier; with the Kia, the 3.1 in higher loading edge results in somewhat more effort and more force required when loading and unloading.

For everyday scenarios with wide or bulky but not extremely long loads, the Kia's slightly greater widths and the same opening height make little difference.

In short: the Audi A6 Avant is the more practical choice when length, deeper usable cargo space, and easier handling during loading and unloading are important; the Kia Sportage is similar in width but has a higher loading edge and significantly less length advantage.
