Trunk comparison: Audi A4 Avant vs VW Passat Wagon

Key Differences (Summary)

The VW Passat Wagon offers longer cargo areas: with the seats folded down, it is 7.1 in (10%) longer, and with the first row of seats upright, it is 3.1 in (8%) longer.

The width differences in favor of the Passat are minor (+2–1.2 in). The trunk opening of the Audi A4 Avant, on the other hand, is 2.4 in (8%) higher. The loading edge of the Passat stands 0.4 in (2%) higher above the road.

Outstanding Difference

The depth of the trunk (loading edge to trunk floor) is 1.6 in greater in the VW Passat Wagon — that is 80% more than in the Audi A4 Avant.

Impact on Usability

The significantly greater depth in the Passat practically means: the cargo volume increases, smaller or less sensitive items can be stored deeper and thus less visible.

For long items (e.g., skis, slats, furniture panels), the Passat is more advantageous due to the longer cargo area — especially with seats folded down. However, the deeper cargo floor can make lifting heavy items more difficult because more height must be overcome or you have to reach further down.

The Audi A4 Avant scores with a higher trunk opening, which makes loading tall, bulky items or easily sliding boxes through easier. The slightly lower loading edge height in the A4 makes lifting heavy loads minimally easier than in the Passat.

In summary: For users who need longer items or as much hidden volume as possible (e.g., craftsmen, families with variable cargo), the Passat is practically better suited. Those who often transport tall, bulky parts or prefer somewhat more comfortable loading of heavy single loads can benefit from the Audi A4 Avant.
