Trunk comparison: Audi A6 Avant vs VW Touran

Key Differences

In terms of cargo space, there is a clear length advantage for the Audi: With all seats upright, the trunk of the Audi A6 Avant is 32.7 in (244%) longer than that of the VW Touran. Even with the first row of seats upright, the Audi is 6.3 in (16%) longer.

Conversely, the trunk opening of the VW Touran is 5.1 in (18%) higher than that of the A6. The stated depth (loading edge to trunk floor) is nominally 0.4 in (100%) greater in the Audi — but the absolute difference is very small.

Other differences (e.g., +6.7 in with seats folded down or width differences of 2 in, or a 0.8 in higher loading edge in the Audi) are below the 10% threshold and are not highlighted here; the width of the trunk opening is the same.

Impact on Usability

The significantly longer interior dimensions of the Audi with upright seating (16% and 244%) provide practical benefits when transporting long or bulky items with full seating: suitcases, long boxes, or items like skis can be transported more easily in the A6 without folding seats down.

This makes the A6 Avant more flexible in everyday use and on longer trips with passengers for longer cargo.

The higher trunk opening height of the VW Touran (+5.1 in / 18%) makes loading tall or bulky items easier and reduces the risk of hitting the upper edge. For frequent loading and unloading of bulky, tall cargo (e.g., crates, plants, strollers), the Touran is therefore more practical.

The nominally 0.4 in greater trunk depth measurement in the Audi hardly matters in everyday use: despite the large percentage, the absolute difference is so small that it is practically negligible.

Conclusion: Those who need more length reserve in the cargo area with a fully occupied car are better off with the Audi A6 Avant.

Those who often load tall, bulky items or value a higher opening for easier loading benefit from the VW Touran. With fully folded seats and regarding trunk opening width, the models are very close.
