Trunk comparison: Audi Q7 vs Fiat Panda

Key Differences
The Audi Q7 offers significantly more cargo space lengthwise: with the seats folded down, the Q7's trunk is 36.2 in (+83%) longer, and with the first row of seats upright, the length advantage is 25.6 in (+120%).
The width of the trunk opening is 8.3 in (+21%) larger in the Q7, while the narrowest point inside the cargo area is only slightly wider (+2.8 in / 7%) than in the Panda.
The Fiat Panda has advantages in other dimensions: the height of the trunk opening is 5.1 in (+17%) higher and the depth between the loading edge and trunk floor is 7.1 in (+1700%) greater. Additionally, the loading edge of the Audi Q7 is 3.5 in (+13%) higher above the ground than that of the Fiat Panda.
Impact on Usability
For long or bulky transports (e.g., long furniture pieces, boards, skis), the Audi Q7 clearly has the advantage: the significantly greater loading length—both with folded seats and with the first row upright—as well as the wider trunk opening make loading easier and allow for longer items without disassembly or major adjustments.
The Fiat Panda scores with tall items and easier lifting: the higher opening height makes it easier to load tall objects, and the much greater depth between the loading edge and trunk floor provides more vertical space inside.
Additionally, the Panda's loading edge is lower than the Q7's, reducing the effort needed to lift heavy loads from the ground and making loading more comfortable during frequent short trips.
Practical conclusions: Those who often transport long or wide items or regularly need larger cargo volumes benefit from the Audi Q7. Those who drive mostly in the city, frequently lift heavy but not necessarily long loads, or prefer tall cargo space with a low loading edge will find more convenient advantages in the Fiat Panda.
