Trunk comparison: Fiat Panda vs Jeep Avenger Electric

Key Differences and Implications for Usability
The Jeep Avenger Electric offers significantly more loading length: with the seats folded down, the trunk is 9.1 in (21%) longer, and with the first row of seats upright, it is 5.1 in (24%) longer than the Fiat Panda.
This makes the Avenger better suited for long items (e.g., skis, long boards, furniture parts) or if you frequently transport longer cargo without fully folding the seats.
The Fiat Panda, on the other hand, scores with vertical space and crosswise utilization: the trunk opening is 3.5 in (11%) higher, the depth from the loading edge to the trunk floor is 2.8 in (64%) greater, and the width at the narrowest point is 4.3 in (12%) wider than the Avenger.
Practically, this means the Panda is easier to load with bulky, tall, or stackable items, offers more usable interior height behind the loading edge, and fits wider cargo at the tightest spot better.
Smaller differences: the Avenger's loading edge is 1.2 in (4%) higher above the ground, which makes lifting slightly more difficult, and the width of the trunk opening differs by only 0.4 in (1%) — both hardly relevant in practice.
Conclusion: Those who need to transport longer items benefit from the Jeep Avenger Electric. Those who often work with tall, stackable, or somewhat wider loads find the Fiat Panda to be the more practical loading solution.
