Trunk comparison: Audi A6 Sedan vs Hyundai Kona

Key Differences (Highlight >10%)
The Audi A6 offers 11.4 in (≈17%) more loading length with the seats folded down and 11.4 in (≈34%) more cargo length with the first row upright than the Hyundai Kona.
The trunk depth (loading edge to floor) is 2.8 in (≈140%) greater in the Audi A6. The Hyundai Kona has a trunk opening height that is 11 in (≈56%) larger and a trunk opening width 3.9 in (≈11%) wider than the Audi A6.
What does this mean for usability?
The longer loading surface of the Audi A6 makes it significantly more practical for long items (e.g., boards, skis) and for more cargo volume with the seats folded down.
Due to the greater trunk depth, the load sits deeper in the cargo space — this increases the usable stacking height above the loading edge and improves securing of low, elongated goods.
The Hyundai Kona, on the other hand, scores points when loading bulky, tall, or wide items: The significantly higher trunk opening makes loading and unloading large, tall boxes and furniture easier; the wider opening simplifies passing through wide parts.
For occasions where volume matters less than access and handling of large individual items, the Kona is more practical.
Small differences such as the 0.8 in higher loading edge or the 0.8 in greater narrowest width in the Kona are unnoticeable in practice — the usage-relevant decisions mainly depend on whether you need longer cargo and more cargo space (Audi A6) or easier access for tall/wide items (Hyundai Kona).
