Trunk comparison: Audi Q7 vs BMW 3 Series Touring

Main Differences (>10%) and Their Impact

The Audi Q7 offers more space in length and width: With the seats folded down, the trunk of the Q7 is 11 in (16%) longer, and with the first row of seats upright, the advantage is 7.5 in (19%).

At the narrowest point, the interior of the Q7 is 5.1 in (14%) wider, and the width of the trunk opening is even 8.3 in (21%) greater than that of the 3 Series Touring.

Practical consequences: Longer items (e.g., skis, slats, long boxes, or furniture parts) can be transported significantly more easily in the Q7. The larger interior and opening width make loading bulky or wide cargo easier and reduce maneuvering when stowing.

Overall, the Q7 is better suited when long or bulky loads need to fit regularly.

Important Disadvantage with Practical Relevance

The loading edge of the Audi Q7 is 7.1 in (30%) higher above the road than that of the BMW 3 Series Touring. This makes lifting heavy or awkward items into the trunk more strenuous and increases the need for aids (ramp, hand truck) or additional muscle power.

For frequent loading and unloading of heavy loads or for users who prefer a lower loading height (e.g., seniors, frequent shopping, heavy boxes), the BMW 3 Series Touring is more practical.

Other, Less Relevant Differences

Small deviations such as the height of the trunk opening (+1.2 in / 4% in favor of the Q7) and the depth from the loading edge seat to the trunk floor (+0.4 in in favor of the BMW) are hardly noticeable in practice and barely affect usability.

Summary

If regularly transporting long or wide items is important, the Audi Q7 is the better choice. Those who frequently lift heavy items or prefer a lower loading height benefit from the lower cargo floor of the BMW 3 Series Touring.
