Trunk comparison: Audi A3 Sportback vs Dacia Duster

Key Differences and Impact on Usability
The Dacia Duster offers significantly more cargo length with the front seats upright than the Audi A3: +7.9 in (26%) longer trunk, making it noticeably better for long items without folding the seats down (e.g., skis, slats, or long boxes).
Additionally, the loading edge of the Duster is +3.5 in (13%) higher above the road, which makes lifting heavy items into the trunk more strenuous and can complicate loading suitcases or furniture.
The Audi A3, on the other hand, has a significantly larger trunk depth measurement between the loading edge and the trunk floor: +3.1 in (100%) greater depth.
This results in a deeper trunk well, which offers advantages for secure storage and stacking of luggage (items sit lower and are less likely to slide out), but at the same time visually deepens the entry area into the cargo space and can limit usable interior height for very tall items.
Other, smaller differences: When all seats are folded down, the Duster still has slightly more length (+5.9 in / 10%), though this difference is borderline for emphasis.
The trunk opening of the Duster is only marginally higher (+1.6 in / 5%) and the width at the narrowest point and the opening differs by about 0.4 in, practically negligible for most uses.
Conclusion: For transporting long items without folding seats, the Duster is clearly advantageous. For better stackable, deeper cargo space and reduced risk of luggage sliding out, the Audi A3 scores higher. The higher loading edge of the Duster, however, makes handling heavy loads less comfortable.
