Trunk comparison: Audi A6 Sedan vs BMW 5 Series Touring

Highlighted Differences (>10%)

Three significant differences stand out from the data: The trunk opening of the BMW is 7.9 in (40%) higher than that of the Audi, the depth of the trunk (measured from loading edge → trunk floor) is 4.7 in (1100%) larger in the Audi, and the width of the trunk opening is 4.7 in (13%) larger in the BMW.

Implications for Usability

The higher trunk opening of the BMW makes it easier to load tall and bulky items: boxes, furniture parts, or upright suitcases can be tilted and pushed through the opening more easily without much twisting or tilting.

Together with the wider opening width, the BMW clearly has the advantage when transporting wide or tall cargo.

The greater depth in the Audi means that the interior space below the loading edge offers significantly more volume. This has a positive effect when cargo is stacked or packed more densely into the trunk; the load sits lower and thus benefits the center of gravity.

At the same time, the greater depth can make reaching into the trunk somewhat more cumbersome (requiring further reaching), and due to the lower opening, very tall items are harder to load despite the greater interior height.

In practice, this means: For regularly bulky, tall, or wide items (furniture parts, larger appliances, bicycle frames without wheels), the BMW 5 Series Touring is more practical.

For more usable volume, a lower luggage center of gravity, and storing heavier, more densely packed loads, the Audi A6 is often more advantageous. The remaining differences in length and narrowest width are minor and have less impact on everyday use.
