Trunk comparison: Audi A6 Avant vs Peugeot 308 SW 3-row

Key Differences (Brief)

The Audi A6 Avant offers significantly more cargo space lengthwise: With the seats folded down, the trunk of the A6 is 20.1 in (35%) longer, and with all rows upright, it is even 32.3 in (234%) longer than the Peugeot 308 SW.

The Peugeot wins in opening height and interior height: The opening of the Peugeot is 6.3 in (22%) higher than the Audi's, and the depth from the loading edge to the trunk floor is 0.8 in (100%) greater in the Peugeot.

The loading edge is higher in the Audi: The loading edge of the A6 is 3.1 in (14%) higher above the road than in the Peugeot.

Other differences are smaller: The width at the narrowest point is only 0.4 in (1%) greater in the Peugeot, and the opening width of the Peugeot is 3.5 in (9%) wider than the Audi’s — both under 10% and thus less relevant in practice.

Impact on Usability

For long items and high cargo capacity with folded seats, the Audi clearly has the advantage.

The significantly greater cargo length (with folded seats +35% or with full seating +234%) makes the A6 better suited for transporting long loads (e.g., furniture parts, skis, long packages) or when substantial cargo space is needed despite full seating rows.

The Peugeot scores with handling-relevant dimensions: the higher opening and the greater depth from the loading edge to the floor make loading tall or bulky items easier (e.g., crates, boxes, tall equipment).

The lower loading edge in the Peugeot makes lifting heavy loads easier and more back-friendly; the Audi’s loading edge, 3.1 in higher, increases the effort required to lift items in.

In practice, this means: Those who regularly transport long loads or a lot of luggage with partially upright seats benefit from the Audi A6 Avant.

Those who frequently load and unload bulky, tall, or heavy items and value easy handling will find the Peugeot 308 SW the more practical solution. Smaller width differences (≤9%) have only a marginal effect on everyday use.
