Trunk comparison: Audi A3 Sportback vs Dacia Jogger

Key Differences
The Dacia Jogger offers significantly more cargo length: with the seats folded down, the trunk is +11.8 in (≈20%) longer, and with the first row of seats upright, it is even +15.4 in (≈51%) longer compared to the Audi A3 Sportback.
The Jogger's trunk opening is also +5.9 in (≈19%) higher, and at its narrowest point, the interior width is +8.7 in (≈22%) greater than that of the A3. In contrast, the Audi A3 has a significantly greater depth between the loading edge and the trunk floor: this distance is +3.1 in (≈100%) larger in the A3 than in the Jogger.
Minor differences (e.g., the A3's loading edge being 0.4 in higher or the Jogger's opening being 6% wider) are not highlighted here.
Impact on Usability
For everyday transport and family use, this means: the Jogger is more practical for long or bulky items and for luggage when the rear seats are in use — the significantly greater length with the seat row upright and the wider narrow width make it easier to load suitcases, strollers, or longer cargo without folding the seats.
The higher trunk opening makes loading tall items easier because more clearance height is available.
The deeper trunk floor of the Audi A3 (more distance between the loading edge and the floor) allows luggage to be recessed below the loading edge, providing a somewhat lower center of gravity for the load or more concealed storage space.
This can be advantageous if you value a flatter external profile of the load or additional hidden storage. The 0.4 in higher loading edge clearance from the road is practically negligible for operation.
In short: those who want maximum usable length, versatile usability, and easy loading (families, lots of luggage, bulky items) clearly benefit from the Dacia Jogger. Those who prefer a deeper load floor with hidden storage and a more compact rear design will find corresponding advantages in the Audi A3.
