Trunk comparison: Opel Grandland vs Skoda Elroq

Key Differences
The Opel Grandland offers a noticeably longer cargo space with the first row of seats upright than the Skoda Elroq: +3.5 in (+11%). With the seats folded down, the lengths are practically the same (only +0.8 in / 1%).
Also notable is the significantly greater trunk depth difference between the loading edge and trunk floor in the Grandland: +5.9 in (+1500%).
The loading edge of the Grandland is also noticeably higher above the road: +3.5 in (+13%). Smaller differences (opening width, opening height, narrowest width) are each in the single-digit percentage range and are less relevant in everyday use.
What impact does this have on usability?
Because the Grandland is longer with the rear seat folded up, it is better suited for longer items with normal seating (e.g., skis, long boxes). When the seats are folded down, both models are nearly equal — offering little advantage for maximum cargo space.
The significantly greater depth between the loading edge and trunk floor in the Grandland means more vertical space in the cargo area and thus more volume usable for stackable or tall items.
This increases flexibility when loading (large boxes, tall bags) but can also mean that heavy items are set deeper and require more reach/bending when removing.
The higher loading edge in the Grandland makes loading and unloading heavy items more strenuous: heavy boxes or furniture must be lifted higher than in the Elroq. Combined with the greater depth, placing bulky but heavy loads can be more practical (because they fit further inside), but physically more demanding.
The smaller differences in width and opening height are hardly noticeable — width and access remain practically comparable in everyday use in both models.
Conclusion: The Opel Grandland is advantageous if you transport longer or taller items with normal seating and want to use more interior volume. The Skoda Elroq offers somewhat better ergonomics when loading and unloading heavy items due to the lower loading edge.
