Trunk comparison: Audi A3 Sportback vs Kia Ceed

Key Differences

In short: the Kia Ceed offers slightly more length and width, while the Audi A3 has significantly more depth.

Specifically, the Ceed has a trunk that is 2 in (3%) longer with the seats folded down and 0.8 in (3%) longer with the first row of seats upright. The narrowest trunk width is 1.6 in (4%) larger in the Ceed, and the opening width is 1.2 in (3%) larger.

The Audi has a trunk opening height that is 0.8 in (3%) greater, and the loading edge is 0.4 in (2%) higher. The most noticeable difference: the trunk depth (loading edge to floor) of the Audi A3 is 2 in or 45% greater than that of the Kia Ceed.

Impact on Usability

The significantly greater depth of the A3 increases the usable vertical or front-to-rear capacity: bulky, tall items are easier to accommodate and transport stacked, overall increasing the volume for block-shaped cargo. Due to the only slightly higher loading edge (+0.4 in), loading remains physically comparable.

The Ceed, on the other hand, has a slight advantage in length and usable width. Longer items (with seats folded down) and wider luggage fit more easily inside, and the somewhat larger opening width makes it easier to slide in wide cargo. These advantages are moderate (3–4%) and mainly affect very flat or wide loads.

Conclusion: For users who frequently transport tall or stacked cargo, the Audi A3 offers noticeable advantages due to the significantly greater depth. Those who more often load longer or wider items and rely on a slightly larger opening have a small advantage with the Kia Ceed.
