Trunk comparison: Audi Q3 vs Seat Ibiza

Key Dimensional Differences

The Audi Q3 offers significantly more cargo length: with the seats folded down, the trunk is 9.8 in (18%) longer, and with the first row of seats upright, it is even 8.7 in (32%) longer than the SEAT Ibiza.

The width of the trunk opening also favors the Q3: it is 9.4 in (27%) larger, while the narrowest trunk width is only slightly (+0.4 in / 1%) in favor of the Q3. In contrast, the SEAT Ibiza has a significantly greater depth between the loading edge and the trunk floor: this is 3.9 in (111%) higher than in the Q3. Smaller differences include the trunk opening height of the Ibiza (+1.6 in / 5%) and the loading edge height of the Q3 (+2.4 in / 9%), each under 10%.

What Are the Practical Implications?

The longer cargo areas of the Audi Q3 (both values >10%) make it more practical for bulky, long items such as furniture parts, skis, long boxes, or a folding bicycle: more usable length means such objects can often be transported without angled loading or folding additional seats.

The significantly larger width of the trunk opening in the Q3 also makes it easier to load wide suitcases, strollers, or bulky shopping loads, as less maneuvering and angling is required.

The SEAT Ibiza scores with the greater depth between the loading edge and trunk floor: practically, this means more vertical volume directly behind the loading edge — advantageous for stacking taller luggage or storing items that need depth (e.g., boxes).

Additionally, the loading edge in the Ibiza is lower (Q3 +2.4 in, but <10%), which makes lifting heavy loads over the sill easier; the slightly higher opening height of the Ibiza (+1.6 in, <10%) helps when loading taller items but is a smaller advantage.

In summary: For longer and wider cargo, the Audi Q3 is clearly better suited; the SEAT Ibiza offers advantages in easier lifting and stacking of taller/more voluminous cargo directly behind the loading edge due to its deeper loading area and lower loading edge.
