Trunk comparison: Audi A6 Sedan vs Dacia Duster

Key Differences
The Audi A6 offers a longer cargo area: 12.2 in (19%) longer with folded seats and 7.1 in (19%) longer with the first row upright than the Dacia Duster.
The height of the Duster's trunk opening is significantly greater: 12.2 in (62%) higher than the Audi A6. The depth of the trunk (distance from loading edge to trunk floor) is 1.6 in (50%) greater in the Audi A6. Additionally, the Duster's loading edge is 3.9 in (15%) higher above the ground than the Audi A6. Smaller differences — such as 0.8 in (2%) more width at the narrowest point in the Audi or 1.6 in (4%) larger opening width in the Duster — are negligible.
Impact on Usability
The longer cargo area of the Audi A6 makes it more practical for long items (skis, furniture parts, long boxes) and for larger luggage volumes with seats folded or upright. Those who frequently transport bulky, longer loads have more room with the A6.
The significantly higher trunk opening of the Duster makes it easier to load tall or bulky items that are height-limited (e.g., tall boxes, plants, crates). However, combined with the higher loading edge, this means heavy loads must be lifted higher in the Duster, making loading more strenuous.
The greater depth in the Audi (loading edge to trunk floor) increases usable interior height/volume in the cargo space and allows for deeper stacking directly behind the loading edge.
Together with the lower loading edge in the Audi, this offers advantages when loading and unloading heavy or bulky items (less lifting effort, better access).
Conclusion: For longer items and frequent, comfortable loading of heavy cargo, the Audi A6 has the advantage. For very tall or bulky single items, the larger opening of the Duster can be practical, but disadvantages arise with heavy loads due to the higher loading edge.
