Trunk comparison: BMW X2 vs Opel Grandland

Key Differences
The most noticeable differences concern the vertical dimensions of the trunk: The loading edge opening of the Opel Grandland is 5.9 in (23%) higher than that of the BMW X2, and the depth of the trunk (loading edge to trunk floor) is 2.8 in (78%) greater in the Grandland.
Other values are significantly smaller: with the front seats upright, the BMW X2 is only about 1.6 in (4%) longer, while with the seats folded down, the Grandland is 1.2 in (2%) longer at the front.
The width at the narrowest point differs by 0.4 in (1%), and the opening width of the Grandland is 3.5 in (9%) larger. The loading edge of the BMW is 0.8 in (3%) higher above the road.
Impact on Usability
The significantly higher opening of the Grandland makes it easier to load tall or bulky items (e.g., boxes, suitcases, strollers) because less tilting or angling is required and more vertical space is available.
The considerably greater depth (loading edge → trunk floor) in the Grandland provides more usable interior height and depth in the cargo area, which simplifies stacking and accommodating bulky or awkward loads.
The slightly longer loading length of the BMW X2 with the front seats upright offers only a small advantage when transporting longer items without folding down the seats. The marginally higher loading edge of the BMW, on the other hand, slightly increases the effort required to lift heavy loads.
Conclusion: For users who frequently load tall or bulky items, the Opel Grandland is noticeably more practical. Those who only occasionally transport longer, flat loads and otherwise value the vehicle concept of the X2 will hardly notice the other differences.
