Trunk comparison: Audi Q2 vs Fiat Panda

Key Differences
The Audi Q2 offers significantly more cargo length: with the seats folded down, the trunk is 13.4 in (31%) longer, and with the first row of seats upright, it is 9.4 in (44%) longer than the Fiat Panda.
In contrast, the Panda scores with more vertical dimension: the trunk opening height is 4.3 in (14%) higher and the depth from the loading edge sill to the trunk floor is 2.8 in (64%) greater than in the Audi. Smaller differences (loading edge height, widths) are under 10% and thus less relevant.
Impact on Usability
The greater cargo length of the Audi Q2 makes it significantly more practical for long items (e.g., skis, long boards, furniture parts) and for luggage that can be placed lengthwise.
Those who frequently transport long or flat loads have fewer restrictions when storing with the Q2 and need to fold or angle items less often.
The Fiat Panda, on the other hand, is advantageous for bulky, taller, or voluminous items: The higher opening provides more headroom when loading and makes it easier to load tall objects that might otherwise risk hitting the upper edge.
The greater depth between the loading edge and floor creates more usable vertical volume and prevents tall items from protruding too much; at the same time, the lower loading edge often makes lifting heavy loads from the floor less strenuous than with the higher Audi load floor.
Width-wise, both vehicles are similar; the slightly larger minimum width and opening width in the Panda (each in the single-digit centimeter range) bring hardly noticeable advantages in practice.
In summary: for long, flat loads, the Audi Q2 is preferred; for tall, voluminous, or frequently heavy-to-lift goods, the Fiat Panda is more practical.
