Trunk comparison: Audi A6 Sedan vs Opel Astra Wagon

Key Differences

The Audi A6 offers a 11.4 in (17%) longer cargo floor with the seats fully folded down compared to the Opel Astra. With the front seats upright, the difference is smaller at +3.1 in (7%).

The trunk opening of the Astra, on the other hand, is significantly higher by 11 in (56%) than that of the A6. The depth of the trunk (from loading edge to trunk floor) is 3.9 in (500%) greater in the A6. The loading edge of the A6 is 2.8 in (12%) higher above the road.

The width of the Astra's trunk opening is 4.3 in (12%) larger; the narrowest width of the trunk is only slightly (+2.8 in / 7%) larger in the Astra.

Impact on Usability

The Audi A6 is better suited for long cargo: the 11.4 in longer cargo floor with folded seats allows storing longer items (e.g., slats, long boxes, skis) without sideways placement.

The significantly greater trunk depth in the A6 (+3.9 in) increases the volume below the loading edge and allows for deeper stacking or placing bulky items that can be "recessed" into the trunk floor.

In contrast, the Opel Astra facilitates loading and unloading heavy or tall items: the 11 in higher trunk opening and the 4.3 in wider opening provide more clearance when maneuvering and standing packages or furniture upright.

Because the loading edge of the Astra is lower (the A6 is +2.8 in higher), lifting bulky or heavy loads is generally easier in the Astra.

In summary: For long or deep cargo, the Audi A6 is advantageous; for simple, straightforward loading of wide, tall, or heavy objects, the Opel Astra Wagon scores better. Smaller differences (e.g., +3.1 in length with upright seats or +2.8 in narrowest width in favor of the Astra) are less decisive in everyday use.
