Trunk comparison: Volvo XC40 vs VW Tiguan

Summary of Measurement Data
The VW Tiguan offers a 1.6 in (2%) longer cargo floor with the seats folded down, while with the first row of seats upright, the Volvo XC40 is 1.2 in (3%) longer. The loading opening of the Tiguan is 0.4 in (1%) higher, and its trunk depth (loading edge to floor) is 0.4 in (0%) greater. The loading edge of the XC40 is 0.4 in (1%) higher above the road. The narrowest width of the trunk is the same in both models, but the loading opening width is 1.2 in (3%) larger in the Tiguan. None of the mentioned differences exceed 10%.
Which Differences Are Relevant in Practice
Since no difference is greater than 10%, the differences in most everyday situations are minor and only affect specific cases. Practically significant are mainly three small advantages: When transporting longer items with the seats folded down, the Tiguan can offer a slightly better fit for long parts due to the 1.6 in greater length. Conversely, the XC40 offers 1.2 in more length with the first row of seats upright, providing slightly more usable trunk space for normal luggage without folding down seats. The slightly larger loading opening width of the Tiguan (+1.2 in) makes loading wider objects near the opening easier; however, the same narrowest interior width means that especially wide loads must be handled similarly further inside both vehicles. The 0.4 in higher loading edge of the XC40 makes lifting very heavy items in slightly more strenuous, while the 0.4 in higher opening of the Tiguan slightly facilitates driving in tall objects. Overall, the effects are small enough that the choice depends more on other factors (seat comfort, driving behavior, equipment, price); those who regularly transport very long or very wide parts should check the mentioned centimeters with a loading test in practice.
