Trunk comparison: Jeep Avenger Electric vs Seat Leon

Key Differences
The SEAT Leon offers more usable trunk space lengthwise overall: when all seats are folded down, the trunk of the SEAT Leon is 5.9 in (≈11%) longer, and with the first row of seats upright, it is even 6.3 in (≈24%) longer than the Jeep Avenger Electric.
Also notable is the difference in trunk depth: the depth (loading edge to trunk floor) of the SEAT Leon is 5.5 in (≈127%) greater, indicating a significantly deeper loading area.
In contrast, the Jeep Avenger is wider at its narrowest point: the minimum trunk width is 3.5 in (≈11%) greater in the Avenger than in the Leon.
Other Minor Differences
The trunk opening of the SEAT Leon is 0.4 in (≈1%) higher; the loading edge of the Leon is 1.2 in (≈4%) higher above the road. The width of the trunk opening is 3.9 in (≈10%) larger in the SEAT Leon — this 10% difference is right at the threshold and was not counted among the highlighted differences.
Impact on Usability
The longer dimensions of the SEAT Leon (both with folded seats and with the first row upright) mean that longer items — such as skis, furniture parts, or longer cargo — can be more easily accommodated in the Leon.
The significantly greater trunk depth of the Leon makes the cargo volume more usable vertically: packages can be placed further inside without hitting the loading edge, creating more usable floor space.
The wider bottleneck in the Jeep Avenger is advantageous for bulky, wide items that need space at the narrowest point of the trunk; here, landscape orientation is more feasible in the Avenger.
The slightly higher loading edge in the Leon (1.2 in) minimally increases lifting effort when loading, while the somewhat higher trunk opening has hardly any practical effect.
Conclusion: For longer and deeper-loading cargo, the SEAT Leon is overall more practical; for very wide, bulky loads, the Jeep Avenger can be more advantageous due to its greater minimum width.
