Trunk comparison: Audi Q2 vs Kia Stonic

Key Differences

Two differences stand out clearly in trunk volume: The Audi Q2 offers a 3.5 in (≈13%) longer cargo space with the first row of seats upright compared to the Kia Stonic.

The Kia Stonic, on the other hand, has a significantly deeper loading floor: the depth from the loading edge to the trunk floor is 2.8 in (≈64%) greater than in the Audi.

What are the practical effects?

The longer cargo space of the Audi Q2 with the rear seat upright means that longer items can be transported more easily without folding down the seats. For passengers with luggage, sports equipment like skis, or longer boxes, the Q2 is more practical in everyday use because more usable length remains behind the seats.

The greater depth in the Kia Stonic creates more usable interior height behind the loading edge and leads – despite a loading edge only 0.4 in higher above the road – to the trunk floor actually being lower.

Practically, this means: more vertical storage volume, better stowing and stacking of crates, bags, or bulky but less long items, and overall a lower center of gravity for the load. This is advantageous for transporting taller, voluminous, or irregularly shaped cargo.

Other, smaller differences

The trunk opening of the Kia is about 0.8 in higher and 2 in wider, and the narrowest width in the cargo area is 2.4 in larger in the Kia. The loading edge of the Kia is 0.4 in higher above the road.

These differences are moderate (<10%) and slightly favor the Kia when loading wider or bulkier items; however, they are less decisive than the two points highlighted above.

Practical recommendation

Those who frequently transport longer items and usually keep the seats upright benefit from the Audi Q2. Those who often carry voluminous, tall, or stackable cargo and value more usable interior height are better off with the Kia Stonic.
