Trunk comparison: Audi A4 Avant vs BMW X2

Key Differences

The Audi A4 Avant offers a +4.7 in (≈13%) longer trunk with the rear seats upright compared to the BMW X2. The trunk opening of the A4 Avant is also significantly higher: +7.5 in (≈29%).

In contrast, the BMW X2 has a trunk depth (distance from loading edge to trunk floor) that is +1.6 in (≈80%) greater, and the loading edge is overall +6.7 in (≈27%) higher above the ground.

There are minor differences in trunk width (±1–3%), which are practically negligible. When all seats are folded down, the A4 Avant has a cargo space that is +6.7 in (10%) longer — this difference is exactly 10% and therefore not highlighted as >10% difference.

Impact on Usability

The longer loading floor of the A4 (especially with the rear seats upright) and the higher opening make it more practical for long or tall items (e.g., longer boxes, skis, bulky furniture parts), as larger items fit more easily in height and can be pushed back into the trunk.

The lower loading edge of the A4 makes lifting heavy cargo into the vehicle easier.

The BMW X2 offers more vertical space below the loading edge due to the greater trunk depth; this is helpful when luggage or equipment needs to be placed deep in the cargo area (e.g., deep boxes or tools).

However, the significantly higher loading edge makes lifting and loading/unloading heavy loads less comfortable. The overall shorter cargo length (especially with the rear seats upright) and the lower opening restrict the transport of very long or tall items more than in the A4.

Conclusion: For regular loading of heavy items or longer/taller cargo, the Audi A4 Avant is usually more favorable in practice. The BMW X2 offers more depth in the cargo area but is less comfortable for loading and unloading large or heavy loads due to the higher loading edge and shorter usable length.
