Trunk comparison: Volvo V90 vs VW ID.4

Key Differences and Impact on Usability

The Volvo V90 offers significantly more loading length: when all seats are folded down, the trunk of the V90 is 9.8 in (15%) longer than that of the VW ID.4, and with the first row of seats upright, it is 7.9 in (21%) longer.

This makes the V90 more practical in everyday use for long items (e.g., slatted frames, long furniture parts, skis) and for situations where longer cargo needs to be transported without significantly changing the seating arrangement.

The VW ID.4, on the other hand, scores with height and volume behind the loading edge: the trunk opening is 3.9 in (14%) higher than on the V90 and the depth from the loading edge to the trunk floor is 3.9 in (900%) greater.

This means the ID.4 is better suited for bulky, tall, or voluminous items that require space in height or are to be stacked above the loading edge.

However, the loading edge of the VW ID.4 is 5.1 in (21%) higher above the ground than that of the Volvo. Practical consequence: heavy loading (e.g., boxes, furniture) requires more effort and is less convenient than with the lower V90; for frequent lifting of heavy loads, the V90 is more ergonomic.

The lateral width differences are small (4–7%) and have little practical impact on usability.

Conclusion: For long, easy-to-lift cargo and comfortable handling, the Volvo V90 is better suited. For very tall or voluminous cargo where the height of the opening and interior volume are decisive, the VW ID.4 is advantageous—provided higher loading edges are acceptable.
