Trunk comparison: Audi Q7 vs Opel Grandland

Summary of Differences

When comparing the cargo geometry, four differences stand out: The Audi Q7 has a trunk that is 13.4 in (20%) longer with the seats folded down than the Opel Grandland and 11.8 in (34%) more length when the first row of seats is upright.

The width of the trunk opening is 5.1 in (12%) larger in the Q7. In contrast, the Opel Grandland offers a depth between the loading edge and trunk floor that is 6.3 in (1500%) greater.

Smaller deviations: The height of the trunk opening is 2.4 in (8%) larger in the Grandland, the narrowest width is 2.8 in (7%) larger in the Q7; the loading edge height is the same on both models.

Impact on Usability

The Audi Q7 is clearly advantageous when it comes to long or wide items: The significantly greater interior length (both with folded seats and with the first row upright) combined with the wider trunk opening makes loading long furniture, skis, slats, or toolboxes easier and allows more flexible loading with full seating.

The Opel Grandland scores with the significantly greater depth from the loading floor to the loading edge. This means more usable vertical height inside the cargo area — practical for tall or bulky items that require more space between the floor and loading edge.

However, the opening itself is narrower and somewhat lower, which can make inserting very wide or very long cargo more difficult.

Since the loading edge height is the same, the required lifting effort when loading and unloading differs practically not between the models.

Smaller differences like the 2.4 in higher opening of the Grandland or the 2.8 in larger narrowest width of the Q7 are noticeable but are secondary in everyday use compared to the main differences mentioned above.
