Trunk comparison: BMW iX1 vs Opel Grandland

Key Differences

Two differences stand out clearly from the measured values: The height of the trunk opening of the Opel Grandland is 3.5 in (≈13%) larger than that of the BMW iX1, and the depth of the trunk (loading edge to trunk floor) of the Opel is 5.5 in (≈700%) larger.

All other deviations are around 1–8% and comparatively small.

Impact on Usability

The greater opening height in the Opel makes it easier to load tall or bulky items: boxes, pieces of furniture, or luggage can be placed upright without needing to tilt them significantly.

The significantly greater depth (loading edge → floor) means more usable interior height behind the loading edge and thus more volume in the cargo area as well as a better ability to store bulky items flat or stacked.

At the same time, the Opel has a loading edge that is 2.4 in higher above the road (≈8%). This makes lifting heavy items somewhat more strenuous compared to the BMW, which offers easier loading of heavy loads due to the lower loading edge.

Smaller differences such as 1–2.8 in (trunk length with seats folded down, width differences) are usually negligible for practical use and hardly affect everyday usability.

In short: Those who often transport tall or bulky cargo and need more usable loading height benefit from the Opel Grandland. Those who frequently load heavy luggage alone and value a lower loading edge have a slight advantage with the BMW iX1.
