Trunk comparison: Mazda Mazda CX-60 vs Skoda Superb Wagon

Key Differences (Highlighted)
The Škoda Superb Wagon offers a significantly longer cargo area when all seats are folded down: +15.7 in or +23% more length than the Mazda CX-60. Likewise, the trunk depth from the loading edge level to the trunk floor is markedly greater in the Škoda: +3.1 in (stated +700%) compared to the Mazda.
On the other hand, the loading edge of the Mazda CX-60 sits noticeably higher above the road: +5.9 in or +25% compared to the Škoda. Smaller differences (under ~10%) concern the trunk width and the height of the trunk opening and are therefore less relevant in practice.
Impact on Usability
The longer cargo area of the Superb with folded seats makes it better suited for long items (e.g., slats, furniture panels, skis) or when transporting longer loads inside the vehicle.
The greater depth from the loading edge level to the floor means more usable vertical space in the trunk of the Škoda — this allows for a higher stacking height below the loading edge and results in more usable volume, especially for bulky, taller items.
The higher loading edge of the Mazda (+5.9 in), on the other hand, works against it: heavy lifting into the trunk becomes more strenuous, and loading large boxes or furniture is less comfortable.
However, a higher load floor can be associated with SUV-typical ground clearance and better visibility in traffic, but it reduces practical loading and unloading convenience.
In short: Those who frequently transport long or bulky cargo will noticeably benefit from the Škoda Superb Wagon (longer cargo area and deeper trunk zone).
Those who primarily value the slightly wider opening width and the SUV driving feel of the Mazda accept the higher effort required for loading and unloading. Smaller differences in width and opening size play only a minor role in everyday use.
