Trunk comparison: Audi A6 Sedan vs VW Tiguan Allspace

Main Differences

The most significant differences concern dimensions that deviate by more than 10%: The trunk of the Audi A6 is +26.8 in (≈145%) longer with the seats upright than that of the VW Tiguan Allspace.

The height of the trunk opening is +8.7 in (≈44%) greater on the Tiguan. The "depth" of the trunk (loading edge to trunk floor) is +4.7 in (≈1100%) greater in the Audi.

The loading edge itself sits +4.3 in (≈17%) higher above the ground on the Tiguan, and the width of the trunk opening is +7.9 in (≈21%) greater on the Tiguan. Smaller differences (about ≈2–5%) exist in lengths with folded seats and the narrowest width; these are less relevant in everyday use.

Impact on Usability

Due to the significantly greater interior length with upright seats and the larger floor depth, the Audi A6 is better suited for longer cargo and for storing items that need to lie flat or long (e.g., furniture parts, long suitcases, or sports equipment).

The greater floor depth increases the usable volume below the opening and makes stacking lower-lying cargo easier. Additionally, the lower loading edge in the A6 is advantageous when lifting heavy loads into the trunk.

The Tiguan Allspace, on the other hand, scores points with bulky, tall, or wide items: the significantly higher and wider trunk opening makes loading large, voluminous parts easier (e.g., wide boxes, tall plants, bulky containers).

The disadvantage is the higher loading edge, which makes lifting heavy loads more strenuous and often requires more effort when loading heavy luggage.

In short: For predominantly long or heavier cargo with frequent lifting, the Audi A6 is more practical; for frequent transport of tall or wide items, the VW Tiguan Allspace is better suited. Smaller differences with folded seats and the narrowest width only marginally affect everyday usability.
