Trunk comparison: Audi Q2 vs BMW i4

Key Differences

The BMW i4 has significantly more cargo length: with the seats folded down, it is +12.2 in (21%), and with the front seats upright +7.9 in (26%) in favor of the BMW.

The Audi Q2, on the other hand, offers a higher trunk opening and more width at the narrowest point: the opening height is +3.9 in (15%) higher and the narrowest width is +4.3 in (13%) larger than the BMW.

The width of the trunk opening is the same; trunk depth (+0.4 in / 10%) and loading edge height (+2.4 in / 9%) differ only slightly.

Impact on Usability

Due to the significantly greater cargo length in the BMW i4, long items (e.g., slats, skis, longer furniture parts, or long boxes) can be stored more easily and completely, especially when the rear seats are folded down. This makes the i4 more practical for transports requiring a lot of depth.

The Audi Q2 is better suited for tall or bulky items: the higher opening makes loading and unloading tall boxes, plants, or bulky objects easier, and the greater width at the narrowest point helps when loading wide, irregularly shaped objects.

However, due to the slightly higher loading edge, lifting heavy loads in may be somewhat more strenuous.

The small differences in trunk depths and loading edge height are practically negligible; the choice primarily comes down to more length (BMW i4) versus more height and slightly more usable width (Audi Q2).
