Trunk comparison: Audi A3 Sportback vs VW Tiguan Allspace
Key Differences
VW Tiguan Allspace offers a loading length that is 16.1 in (28%) longer with the seats folded down than the Audi A3 Sportback. Even with the first row of seats upright, the Tiguan is 13.8 in (45%) longer.
In everyday use with all seats upright, the Audi A3 Sportback has a loading area that is 11.8 in (64%) longer than the Tiguan.
The depth of the trunk (loading edge to trunk floor) is 6.3 in (1500%) greater in the Audi, indicating a significantly deeper cargo space below the loading edge.
The loading edge of the VW Tiguan Allspace is 3.9 in (15%) higher above the road, and the width of the trunk opening in the Tiguan is 6.7 in (18%) larger.
Smaller differences under 10% and thus less relevant: The height of the trunk opening is +2 in (7%) higher in the Audi, and the narrowest trunk width is only +0.4 in (1%) larger in the Tiguan.
Impact on Usability
For long items, furniture, or bulky loading with folded seats, the Tiguan is clearly advantageous: the significantly greater loading length (±16.1 in) and the wider trunk opening (±6.7 in) make it easier to load long and wide parts.
When all seats are occupied, the Audi A3 Sportback provides more usable depth behind the seats (+11.8 in), offering more space for groceries, luggage, or bags when fully occupied.
The much deeper trunk area in the Audi (±6.3 in) allows luggage to be recessed below the loading edge — an advantage for volume with a lower center of gravity. However, this can make lifting and removing heavy items from the deep compartment somewhat less convenient.
The higher loading edge of the Tiguan (+3.9 in) makes loading heavy items at shoulder height more strenuous, but a higher loading edge often prevents lateral shifting and offers better partitioning options in some uses. The larger opening of the Tiguan facilitates sliding in wide parts despite the higher loading edge.
Conclusion: For regularly carrying long or wide loads (folded seats) and flexible loading, the VW Tiguan Allspace is better suited. For more usable storage space with full occupancy and a deeper cargo compartment, the Audi A3 Sportback is the more practical choice.
