Trunk comparison: Audi Q7 vs Volvo V90
Summary of Differences
The Audi Q7 offers a trunk that is 3.5 in (5%) longer with the seats folded down and 2 in (4%) longer with the first row of seats upright compared to the Volvo V90. The height of the Q7's trunk opening is 2 in (7%) greater, while the depth (loading edge to trunk floor) is the same.
The width at the narrowest point is 1.2 in (3%) wider in the Q7, and the width of the trunk opening is 2.8 in (6%) wider. Particularly notable is the loading edge height: the Audi Q7's loading edge is 6.7 in (28%) higher above the ground than the Volvo V90's.
Most Significant Difference (>10%)
The significantly higher loading edge of the Audi Q7 (6.7 in / 28%) is the largest practical difference. This means that loading and unloading heavy or bulky items requires more lifting strength; loading demands more effort and is less back-friendly.
For frequent, heavy loads or frequent lifting, the Volvo V90 is more ergonomic and comfortable; for bulky items, the higher loading edge of the Q7 can make loading with ramps or aids more difficult.
Other Differences and Their Impact
The slightly greater overall length of the Q7 (3.5 in or 2 in more) provides minimally more cargo volume with seats folded or upright but only moderately affects everyday usability and packability. The 2 in higher trunk opening of the Q7 makes it somewhat easier to load taller items but remains a minor advantage.
The same applies to the slightly greater width of the Q7 at the narrowest point and the opening—useful for wide loads but only marginally decisive. Since the depth remains the same, usability in this dimension is identical.
Conclusion
For users who frequently load and unload heavy or low-lying cargo, the Volvo V90 is more practical due to the lower loading edge.
Those who occasionally need a bit more trunk length and a slightly larger opening have small advantages with the Audi Q7. The most practically important difference remains the Q7's 28% higher loading edge and the resulting ergonomic strain when lifting.
