Trunk comparison: Audi A4 Avant vs Seat Tarraco

Key Differences

The SEAT Tarraco offers a significantly wider trunk opening: +5.1 in (13%) compared to the Audi A4 Avant.

Two other notable relative differences for the Tarraco are the measured depth between the loading edge and trunk floor, which is +0.4 in (20%) greater, and the loading edge overall sits +4.7 in (19%) higher above the road.

Smaller deviations include the slightly larger cargo volume with folded seats (+1.6 in / 2%) and with the first row upright (+2.8 in / 7%), the trunk opening height is +0.8 in (2%) higher on the A4, and the narrowest width in the trunk is only +0.8 in (2%) larger on the Tarraco.

Impact on Usability

The wider trunk opening of the Tarraco (+5.1 in) makes loading and unloading large, wide items (e.g., furniture, large boxes, or bicycles) significantly easier — requiring less maneuvering and repositioning.

The higher loading edge of the Tarraco (+4.7 in) makes lifting heavy loads onto the cargo floor more strenuous; for regularly storing heavy items, the lower A4 loading floor is advantageous because it requires less effort.

The greater depth between the loading edge and trunk floor in the Tarraco (+0.4 in, formally +20% relative) means the trunk floor immediately behind the loading edge is slightly deeper.

Practically, this results in a bit more space in the trunk recess directly behind the opening — but the effect is very small (only 0.4 in) and hardly noticeable for most loading tasks.

In summary: Those who frequently transport wide or bulky items benefit from the Tarraco due to the significantly larger opening. Those who often lift heavy loads or prefer a lower loading edge have the practical advantage with the Audi A4 Avant.
