Trunk comparison: Kia Stonic vs Mazda Mazda CX-60

Key Differences

The Mazda CX-60 offers significantly more length in cargo volume: when all seats are folded down, the CX-60 is 14.2 in (26%) longer, and with the first row of seats upright, it is 11.4 in (42%) longer than the Kia Stonic.

Also notable is the depth between the loading edge and the trunk floor: the Kia Stonic is 7.1 in (1700%) "deeper" here than the CX-60.

Impact on Usability

The longer cargo areas of the CX-60 make it better suited for long items (e.g., furniture parts, long skis, bulky suitcases) and overall more luggage volume, especially when the rear seats are folded down. The greater length with the seat row upright also means more usable depth during passenger operation.

The large difference in depth between the loading edge and trunk floor in the Kia indicates a significantly more pronounced interior step in the trunk: the volume sits deeper below the loading edge.

In practice, this means on one hand more storage space "under" the loading edge, but on the other hand, the combination of a higher loading edge (Kia is 1.2 in or 4% higher above the road) and this deep interior area makes lifting heavy or bulky items more difficult.

The Mazda has a flatter transition height and thus overall a more ergonomic loading height for heavy loads.

Other, smaller differences: The CX-60's trunk opening is 3.9 in wider (a practical advantage when loading wide items), the opening height and the narrowest width of the trunk differ only slightly (each by 1–4%) and are less decisive in everyday use.
