Trunk comparison: Tesla Model Y vs VW T-Roc

Key Differences
The Tesla Model Y offers a significantly longer cargo space: with the seats folded down, the Model Y is 18.1 in (31%) longer, and with the first row upright, it is 13 in (42%) longer compared to the VW T-Roc.
The VW T-Roc, on the other hand, has larger dimensions for the trunk opening and depth: the trunk opening is 6.7 in (25%) higher, the depth (loading edge to trunk floor) is 8.7 in (2100%) greater, and the width of the trunk opening is 4.7 in (12%) wider than the Model Y.
The narrowest width inside the trunk is only 6% larger in the T-Roc, and the loading edge in the T-Roc is 2.8 in (10%) higher above the ground.
Impact on Usability
For long items (boards, furniture boxes, skis, etc.), the Model Y clearly has the advantage: the significantly longer cargo space allows for storing longer parts, even with the rear seat upright. Due to the lower loading edge height of the Model Y, heavy or long items can also be slid in and over the edge more easily.
The VW T-Roc is more advantageous for tall, bulky, or wide loads: the higher opening and larger opening width make it easier to load tall or wider items, and the greater depth of the cargo area offers more vertical space or a deeper trunk where bulky items can be placed.
However, the higher loading edge (by 2.8 in) means a bit more lifting when loading and unloading heavy loads.
In summary: Model Y = better for longer loads and easier handling over the lower loading edge. T-Roc = better for tall, wide, or bulky loads thanks to the higher opening, deeper cargo space, and larger opening width.
