Trunk comparison: Ford S-MAX vs Volvo V90

Key Differences and Their Impact on Usability
The Ford S‑Max stands out primarily due to significantly more vertical space: the trunk opening of the S‑Max is 9.1 in (33%) higher than that of the Volvo V90. This makes loading tall or bulky items much easier because less tilting and turning is required, and bulky parts can fit standing up or at a smaller angle into the cargo area.
Additionally, the depth of the trunk in the S‑Max (measured from the loading edge to the trunk floor) is 1.2 in (200%) greater. Practically, this means the S‑Max offers more usable interior space below the loading edge, allowing flat or stacked cargo to be stored better.
At the same time, the cargo sits lower, which can reduce visibility over the cargo area and make retrieving items lying deeper somewhat more cumbersome.
Smaller differences that complement everyday usability: the loading edge of the Volvo V90 is 1.6 in (7%) higher above the road than that of the S‑Max, making it somewhat easier to lift heavy items into the S‑Max.
The width of the trunk opening is 3.1 in (8%) larger on the V90, and the width at the narrowest point as well as the trunk length with the first row of seats upright differ by only 2% in favor of the V90; folded down, the S‑Max is only 2% longer.
These smaller width and length differences have only a marginal effect on usability for very wide or long items.
Conclusion: Those who frequently transport tall or bulky, stackable cargo or value a lower loading and unloading height benefit from the Ford S‑Max.
Those who need slightly more width at the opening or minimally longer usable lengths for flat, wide items are better served by the Volvo V90, which offers these advantages only to a small extent.
