Trunk comparison: Audi A6 Sedan vs Kia Sportage

Key Differences

The Audi A6 offers more cargo length: with the seats folded down, it is 10.2 in (+15%) longer, and with the first row upright, 9.8 in (+28%) longer compared to the Kia Sportage. The Kia's trunk opening is significantly higher: it is 9.1 in (+46%) larger than the Audi's.

The trunk depth (loading edge to trunk floor) is much more pronounced in the Audi: 4.7 in (+1100%) more than the Kia. Additionally, the width of the trunk opening is 4.3 in (+12%) larger in the Kia.

Smaller differences such as loading edge height (+2.4 in / 9%) or the narrowest trunk width (+0.8 in / 2%) are minor and not highlighted here.

Impact on Usability

The Audi A6's advantages in length and depth mean it is better suited for long items (e.g., roof rack parts, skis, long boxes) and for larger usable cargo volumes with the seats folded down.

The greater depth creates more usable volume but can also mean that very tall items cannot stand upright because the opening height in the Audi is smaller.

The Kia Sportage, with its significantly higher and wider opening, is better suited for bulky or tall cargo (e.g., plants, stacked crates, furniture parts) that is limited in height or width.

The wider loading opening makes loading and unloading bulky items easier, while the slightly shorter cargo length can restrict long items.

In practice, this means: Those who frequently transport long cargo or need maximum storage space with folded seats benefit more from the Audi A6. Those who more often transport wide or tall, bulky cargo and value easy loading and unloading through a larger opening are better off with the Kia Sportage.
