Trunk comparison: Audi Q3 vs Seat Tarraco

Key Differences

The SEAT Tarraco offers a significantly larger cargo space with the seats folded down: +8.3 in (13%) longer loading floor than the Audi Q3. Even with the first row of seats upright, the Tarraco remains clearly ahead: +8.7 in (24%) longer loading floor.

On the other hand, the Audi Q3 has a deeper cargo floor (distance from loading edge to trunk floor) by +1.2 in (50%) compared to the Tarraco.

Other differences are minor: the Tarraco's trunk opening is 2 in (6%) higher, the narrowest width is 0.4 in (1%) larger, and the opening width is 1.2 in (3%) larger; the loading edge height is the same.

Impact on Usability

For transport tasks requiring a lot of length or volume, the Tarraco has the advantage. The 13%–24% larger loading floor practically means more space for long items and bulky cargo with seats folded down or upright.

Those who regularly transport furniture parts, long building materials, or luggage for longer trips noticeably benefit from this additional space.

The deeper cargo floor of the Audi Q3 (+1.2 in / 50%) creates a bit more of a "well" directly behind the loading edge in the trunk.

This helps to store flat or smaller items more securely and reduces shifting; additionally, there is slightly more interior height available in this area. The equal loading edge height of both models makes lifting luggage similarly comfortable.

The moderate advantages of the Tarraco in opening and interior height (+2 in) as well as in width (+1–1.2 in) make loading somewhat easier but do not represent fundamental differences in usability.

In summary: Tarraco = noticeably more usable length/volume (especially with rear seats upright and folded down). Audi Q3 = slightly more practical floor design for secure storage of flat loads.
