Trunk comparison: Audi Q3 vs Hyundai IONIQ

Key Differences (highlighted deviations >10%)

The dimensions show few but relevant differences: the trunk opening of the Audi Q3 is 4.7 in (18%) higher than that of the Hyundai IONIQ, the width of the trunk opening on the Audi Q3 is 7.1 in (19%) larger, and the depth of the trunk (loading edge to trunk floor) on the Hyundai IONIQ is 1.2 in (33%) greater.

Smaller deviations (trunk length with folded seats +1.2 in/2%, rear seat upright +0.4 in/1%, loading edge +0.4 in/1%) are negligible; the narrowest width is the same on both models.

Impact on Usability

The greater opening height and width of the Audi Q3 make loading and unloading bulky, wide, or tall items easier: furniture parts, large boxes, strollers, or sports equipment can be maneuvered more easily straight through the opening without needing to angle or tilt significantly.

Everyday loading and unloading is also more comfortable because there is more room to handle items.

The Hyundai IONIQ offers more usable interior volume vertically due to the greater depth (loading edge to floor): items can lie deeper and thus often more securely in the cargo space, making stacking easier.

However, the opening is lower and narrower, so very tall or wide items may theoretically fit inside but might not pass easily through the opening or may need to be tilted when loading.

Practical conclusion: If you often transport wide or tall items or value easy, comfortable loading, the Audi Q3 has the advantage. If you prefer deeper storage space for stacked or elongated luggage and the opening dimensions are less critical, the Hyundai IONIQ can be more practical.
