Trunk comparison: BMW X1 vs Jeep Avenger Electric

Key Differences
The BMW X1 offers significantly more cargo length: with the seats folded down it is 11.8 in (22%) longer, and with the first row of seats upright 9.1 in (34%) longer than the Jeep Avenger Electric. The narrowest trunk width is 4.3 in (12%) larger in the BMW.
In contrast, the Jeep Avenger Electric has a significantly greater trunk depth setting (loading edge to trunk floor): 3.1 in (267%) deeper than the BMW.
Smaller differences under 10% include: the Jeep's trunk opening height is 2.8 in (10%) higher, the Jeep's loading edge is 0.4 in (1%) higher, and the BMW's trunk opening width is 3.1 in (8%) larger.
Impact on Usability
Because the BMW X1 offers significantly more length and slightly more width, it is better suited for long or flat items (e.g., furniture parts, skis, long boxes) and for transports where the seats are regularly folded down.
The greater narrowest width makes storing wider packages and efficiently loading multiple boxes easier.
The deeper loading floor of the Jeep Avenger creates more vertical capacity directly under the loading edge, allowing taller or stacked items to be stored more stably.
At the same time, the greater trunk depth can make loading and unloading heavy cargo more difficult because it extends further down, making lifting and reaching more demanding.
The slightly higher trunk opening height (+2.8 in) helps with sliding in tall cargo, while the minimally higher loading edge (+0.4 in) barely increases the effort needed to lift items in.
Conclusion: For regularly transporting long or wide items, the BMW X1 is the more practical choice. For more usable depth and stackable, bulky cargo, the Jeep Avenger Electric is advantageous, though at the cost of somewhat more cumbersome access to the trunk floor.
