Trunk comparison: Tesla Model Y vs Durchschnitt Compact SUV

Key Differences
The Tesla Model Y offers significantly more cargo length: with the seats folded down, the trunk is 17.7 in (30%) longer, and with the first row upright, it is 13.4 in (44%) longer than the average compact SUV.
Conversely, the average SUV has a taller trunk opening: the opening height is 3.9 in (14%) greater than that of the Model Y. Also notable is the depth from the loading edge to the trunk floor in the average SUV, which is 5.5 in (1300%) greater than in the Model Y.
Impact on Usability
The greater cargo length of the Model Y makes it better suited for long items (skis, boards, long furniture parts) and provides more usable cargo space even with the first row fully occupied. Folding down the seats creates a significantly longer, more practical loading surface for bulky, flat cargo.
The taller trunk opening of the average SUV makes it easier to load tall or bulky items (boxes, cabinets, tall suitcases) and prevents bulky parts from hitting the opening.
The significantly greater depth between the loading edge and trunk floor in the average SUV creates more vertical volume but also means a deeper interior below the loading edge: this can make sliding in very flat items more difficult and makes lifting/lowering heavy cargo less comfortable because you have to lift further down.
In short: Those who frequently transport long, flat, or very bulky items benefit from the Tesla Model Y. Those who often need to carry tall or bulky items or want more vertical storage volume in the floor area have advantages with the average compact SUV.
