Trunk comparison: BMW X4 vs Volvo V90

Key Differences

The Volvo V90 offers more usable cargo space especially in length: with the seats folded down it is +8.7 in (13%) longer, and with the first row upright it remains +4.7 in (12%) longer than the BMW X4. The trunk opening of the Volvo is also +4.3 in (11%) wider.

In contrast, the BMW X4 has a significantly deeper loading floor (distance from loading edge to trunk floor) by +3.1 in (700%) and a significantly higher loading edge to the road by +7.1 in (30%).

The height of the trunk opening is the same in both models; the narrowest width inside the trunk is 2 in (5%) larger in the Volvo, but this difference is under 10%.

Impact on Usability

Volvo V90: The greater cargo length (both with folded seats and upright seat row) and the wider opening make the V90 more practical for long and wide items such as furniture, skis, or long boxes.

The lower loading edge (compared to the X4) makes lifting heavy loads into the trunk easier and reduces physical effort when loading.

BMW X4: The greater trunk depth means items can sit further down – this helps to store bulky but not very long cargo compactly and deeper, lowering the center of gravity and securing the load better.

However, the significantly higher loading edge makes lifting heavy items more difficult. The shorter length and narrower opening limit the volume for long or very wide items compared to the V90.

In summary: For longer and wider cargo as well as easier lifting, the Volvo V90 is the more practical choice. For deeply nested, compactly stacked cargo, the BMW X4 can offer advantages, at the cost of more difficult loading due to the higher loading edge and less space for long items.
