Trunk comparison: Jeep Avenger Electric vs Kia Ceed

Notable Differences (>10%)
The Kia Ceed offers a cargo area that is 7.9 in (15%) longer with the seats folded down than the Jeep Avenger Electric. With the seats in the normal upright position, the Kia Ceed's trunk is 4.7 in (18%) longer.
Additionally, the narrowest width in the trunk of the Kia Ceed is 5.1 in (14%) larger than that of the Jeep Avenger Electric.
Other Dimensions (under 10%)
The trunk opening is 1.6 in (5%) higher on the Jeep Avenger Electric, and the loading edge of the Jeep is 2.4 in (9%) higher above the ground. Depth (loading edge to trunk floor) is the same for both models; the width of the trunk opening differs by only 0.4 in (1%) in favor of the Kia Ceed.
What Impact Do These Differences Have on Usability?
More length in the Kia Ceed (with seats folded +7.9 in / with seats upright +4.7 in): practical advantages when transporting long items (skis, slats, furniture parts).
In everyday use with seats upright, the Kia clearly has more usable cargo space, making it easier to accommodate bulky groceries, strollers, or luggage.
Greater narrowest width in the Kia (+5.1 in): allows loading wider items without repositioning. For crates, wide furniture parts, or transporting bicycles (crosswise), the Kia is more flexible inside; in the Jeep, the narrowest point can become a limiting factor.
Advantages of the Jeep despite smaller length and width: the trunk opening is slightly higher (+1.6 in), making it easier to load comparatively taller but narrower items. However, the higher loading edge (+2.4 in) makes lifting heavy loads more strenuous and worsens ergonomics when loading and unloading.
Summary
For users who frequently transport long or wide items or need a lot of cargo space with seats upright, the Kia Ceed is the more practical choice.
The Jeep Avenger Electric scores with a slightly higher opening height but has a higher loading edge and overall less usable length and width, which limits loading large/heavy items.
