Trunk comparison: Jeep Avenger Electric vs VW Touran

Key Differences
When it comes to pure cargo space, there is a clear picture: The VW Touran offers significantly more length with the seats folded down — +17.7 in (+34%) — and also with the first row of seats upright, the Touran is noticeably longer — +13.4 in (+51%).
In contrast, the Jeep Avenger Electric has a larger trunk with all seats upright, namely +13 in (+97%) more length than the Touran.
Other notable differences are the significantly greater installation depth of the Avenger (depth from loading edge to trunk floor: +3.9 in, approx. +1000%) and the higher loading edge of the Avenger (+3.9 in, +16%).
In the narrowest width, the Touran is wider (+5.9 in, +17%). Smaller differences under 10% concern the height and width of the trunk opening and are less relevant.
Impact on Usability
For large, long items or when the rear seats are regularly folded down, the VW Touran is better suited due to the significantly greater length in the folded state: it accommodates longer cargo and offers more usable payload when transporting bulky loads.
The greater narrowest width also makes the Touran more practical for wide boxes or items with little side clearance.
The Jeep Avenger Electric scores in everyday use with more usable length when all seats are upright — that is: with full occupancy, the Avenger offers more cargo space behind the seats, which is advantageous for shopping, luggage, or medium-sized bags with passengers.
The significantly greater depth of the trunk means more vertical storage space below the loading edge (more "floor space"), but can also mean that items lie deeper and are harder to access.
The higher loading edge of the Avenger also increases the effort required to lift heavy items in, while the lower sill of the Touran makes loading and unloading easier.
Overall: Touran = better for longer/bulky cargo and easier handling when loading; Avenger = more practical everyday trunk with greater depth and more volume with all seats upright, but with a higher loading edge and thus more lifting effort.
