Trunk comparison: Audi Q7 vs Peugeot 308 SW 3-row
Trunk Volume and Loading Length
The Audi Q7 offers significantly more loading length: with the seats folded down, the Q7's trunk is 22.8 in (≈40%) longer than the Peugeot's, and with the seats upright, even 33.1 in (≈240%) longer.
This clearly makes the Q7 superior when transporting long items or considerably more luggage — especially without or with only partially folded seats.
Loading Opening and Interior Height
The Peugeot has the taller trunk opening: the opening height is 5.5 in (≈19%) higher than the Q7's, and the measured depth from the loading edge apex to the trunk floor is 1.6 in (≈300%) greater.
This means that tall cargo fits better through the opening and vertically inside the Peugeot; tall items are easier to position. In contrast, the Q7's opening is lower but offers other advantages due to the longer loading surface.
Loading Edge and Handling
The Audi Q7's loading edge is 8.7 in (≈39%) higher above the road than the Peugeot's. Practically, this means lifting heavy items into the Q7 is more strenuous and requires more strength or aids; conversely, loading and unloading in the Peugeot is more ergonomic because the loading edge is lower.
Width and Loading Width
The width differences are minor: the narrowest trunk point in the Q7 is only about 2.8 in wider, and the opening width in the Q7 is about 3.1 in larger — both below the 10% threshold.
In practice, this slightly eases loading very wide, flat items in the Q7 but does not create a fundamental usage difference compared to the Peugeot.
Conclusion: Differences in Usability
In summary, two clear usage profiles emerge: The Audi Q7 is the better choice when you need to transport long or many items — especially when a larger loading area with folded or even upright seats is required.
The Peugeot 308 SW (3-row) scores points for easier loading and unloading (lower loading edge) and better vertical fit for tall items thanks to the higher opening and deeper trunk floor.
Which variant is more practical thus depends on the more frequent use case: lots of volume and length → Q7; ergonomic loading/unloading and space for tall cargo → Peugeot.
