Trunk comparison: Volvo XC40 vs VW Touran

Main Differences (>10%)
The VW Touran offers a +3.9 in (≈11%) longer cargo floor when the first row of seats is upright. The Volvo XC40, on the other hand, has a significantly larger cargo floor when all seats are upright: +22.4 in (≈168%) more length than the Touran.
The height of the trunk opening is +5.1 in (≈18%) higher in the Touran than in the XC40. At the same time, the loading edge of the Volvo XC40 sits +5.1 in (≈21%) higher above the ground than in the Touran.
Implications for Usability
The much larger cargo floor of the XC40 with all seats upright makes it practical for everyday luggage transport with full occupancy (groceries, luggage, stroller behind the seat rows): more usable storage space without having to fold down seats.
The Touran is advantageous when longer items need to be loaded without adjusting the front seats — here it offers the longer usable depth.
The higher trunk opening of the Touran makes it easier to load tall items and provides more vertical clearance when loading.
The higher loading edge in the XC40 means more lifting effort when loading heavy items; loading and unloading heavy or bulky cargo is more ergonomic in the Touran because the loading edge is lower.
In summary: For maximum cargo space with full occupancy, the Volvo XC40 is better suited. For comfortable handling of heavy or tall loads and for longer items without folding seats, the VW Touran scores better.
