Trunk comparison: Audi A6 Sedan vs Durchschnitt SUV

Key Differences

The Audi A6 offers significantly more cargo length: +13.4 in (21%) when all seats are folded down and +11.8 in (35%) with the first row upright.

The trunk depth (loading edge → trunk floor) is +2.8 in (140%) greater in the A6. In contrast, the average SUV has a significantly taller trunk opening: +10.6 in (54%) in opening height and a wider opening width of +4.7 in (13%).

The SUV's loading edge is also +3.5 in (14%) higher above the ground. The width at the narrowest point differs by only +0.4 in (1%), which is practically negligible.

Impact on Usability

Due to the greater cargo length, the Audi A6 is better suited for long items (e.g., skis, slats, long boxes) and for flat, elongated loads with seats folded down.

The greater trunk depth also means more usable interior space from the loading edge downward — this makes it easier to securely set or stack items near the cargo floor.

The SUV, on the other hand, is better suited for tall or bulky items: the higher opening height and wider opening facilitate loading bulky, tall cargo or furniture pieces that might not fit in the Audi due to the lower opening geometry.

However, the SUV's higher loading edge makes handling heavy items more difficult (requiring more effort to lift), while the lower loading height of the A6 makes loading and unloading heavy bags or boxes easier.

In short: Audi A6 = advantage in length, depth, and easier loading/unloading of seated/lying cargo. Average SUV = advantage in height and width of the opening for bulky, tall, or wide-format items.
