Trunk comparison: Jeep Avenger Electric vs Durchschnitt Subcompact

Key Differences
The most noticeable difference concerns the depth of the trunk: the average subcompact has a trunk depth (loading edge → trunk floor) that is 3.1 in (73%) greater than the Jeep Avenger Electric.
Other, smaller differences: the Jeep Avenger offers a loading length that is 2.4 in longer with the seats folded down and 1.6 in more length with the first row of seats upright.
The width of the trunk opening is 3.1 in (≈9%) wider on the Avenger, while the subcompact is 3.1 in (≈9%) wider at the narrowest point inside the trunk. The height of the trunk opening (+0.8 in) and loading edge height above the road (+0.4 in) are slightly ahead in the average subcompact.
Impact on Usability
The significantly greater depth of the subcompact creates more vertical volume: it accommodates taller or stacked luggage better and offers more overall storage space vertically.
This makes the subcompact advantageous when frequently transporting tall items or a lot of stackable cargo. However, the deeper loading well also means that heavy items must be lowered further into the vehicle — loading can therefore be somewhat more cumbersome.
The Jeep Avenger benefits from a wider tailgate opening and a slightly longer loading floor (with seats upright and folded down).
This facilitates inserting wider or longer items and loading heavy loads, as the loading floor is (relatively) flatter/easier to reach. However, the narrower interior width at the tightest point can limit the accommodation of very wide cargo inside the trunk.
Since the height of the opening and loading edge height vary little, floor-to-load conditions are similar across vehicles.
In summary: for more vertical volume and stackable cargo, the average subcompact is better suited; for easier handling of heavy or long items and inserting wider parts, the Jeep Avenger is more practical.
