Trunk comparison: Audi A6 Sedan vs BMW X2

Key Differences and Impact on Usability

The Audi A6 offers significantly more usable cargo space lengthwise: with the seats folded down, the trunk of the A6 is 11.4 in (≈17%) longer, and with the first row of seats upright, it is 8.7 in (≈24%) longer than in the BMW X2. This makes the A6 clearly better suited for long items (e.g., furniture parts, long pipes, skis) and for loading bulky, elongated cargo.

In terms of vertical accessibility, the BMW X2 has advantages: the height of the trunk opening is 6.3 in (≈32%) larger in the X2. This makes it easier to accommodate bulky, tall cargo in an upright position in the X2 because the opening offers more vertical clearance.

However, the loading edge of the X2 is 5.5 in (≈21%) higher above the road than in the A6, which makes lifting heavy items into the trunk more strenuous.

The Audi A6 also has a greater trunk depth (distance from loading edge to trunk floor): about +1.2 in (≈33%). Practically, this means there is more storage space behind the loading edge in the A6, and cargo sits somewhat deeper and thus more stable — advantageous when stacking or transporting flat, heavy goods.

Other Differences and Conclusion

The width differences are minor: the narrowest trunk width of the A6 is only 0.8 in (≈2%) larger, and the opening width of the X2 is 2 in (≈5%) larger; these deviations have little impact in everyday use.

In summary: For longer or deeper cargo as well as easier loading and unloading of heavy items, the Audi A6 is the more practical choice.

The BMW X2 offers a larger vertical opening, which helps when loading tall items, but loses ergonomics due to the higher loading edge when lifting. The width differences are negligible.
