Trunk comparison: Audi Q7 vs BMW i4

Key Differences

There are several clear differences in the trunk favoring the Audi Q7: The Q7 offers +10.6 in (15%) more length with the seats folded down and +8.3 in (21%) more length with the first row of seats upright than the BMW i4. The trunk opening of the Q7 is +3.1 in (12%) higher, the narrowest width in the cargo area is +7.9 in (23%) larger, and the width of the trunk opening is +10.6 in (29%) larger than in the i4. In contrast, the BMW i4 has a 3.9 in (900%) greater depth between the loading edge and the trunk floor.

Additionally, the loading edge of the Q7 is +3.1 in (11%) higher above the road than that of the i4.

Practical Implications / Usability

The greater length and width dimensions of the Q7 make it significantly more practical for long, wide, or bulky cargo (e.g., furniture, long items, moving boxes, or skis).

The larger opening height and wider opening facilitate loading and unloading bulky parts. Since the Q7 also offers more cargo space with the first row of seats upright, it is overall more flexible for family and leisure use.

However, the higher loading edge of the Q7 (+3.1 in) increases the effort required to lift heavy items inside; frequent loading of heavy goods is ergonomically less favorable than in the i4. The BMW i4 scores with its significantly greater depth between the loading edge and trunk floor: combined with the lower loading edge, this allows easier sliding in and stacking of flat or heavy items without having to lift them much.

For users who primarily want frequent, ergonomically easy loading of smaller/handy cargo in the city, the i4 can be more practical.

In summary: Those who regularly need to transport long, wide, or very bulky loads are better served by the Audi Q7. Those who prioritize a low loading edge and easy sliding in with moderate cargo size benefit more from the BMW i4.
