Trunk comparison: Tesla Model Y vs VW T-Cross

Key Differences
The Tesla Model Y offers a significantly longer cargo space: With the seats folded down, the trunk of the Model Y is 19.3 in (34%) longer than that of the VW T-Cross, and with the first row of seats upright, it is even 17.7 in (68%) longer. The VW T-Cross, on the other hand, has a considerably greater depth between the loading edge and the trunk floor — +6.3 in (1500%) compared to the Model Y.
Minor differences (under 10%) concern the height of the trunk opening (+0.4 in in favor of the T-Cross), the loading edge height above the ground (+0.4 in in favor of the T-Cross), the narrowest width (+2 in in favor of the T-Cross), and the width of the trunk opening (+1.2 in in favor of the Model Y). These hardly affect everyday use.
Impact on Usability
Due to the significantly greater loading length, the Model Y clearly has the advantage for long items like slats, skis, pipes, or furniture parts. Even when the front seats are in use, longer items can be transported — making the Model Y more practical for tradespeople, DIY shopping, or vacations with bulky luggage.
The greater depth in the T-Cross means the trunk floor lies significantly lower below the loading edge. This creates a "recess" where smaller items can be well concealed and are less likely to shift.
At the same time, loading heavy items can be somewhat less convenient because more lifting effort is required and loading is not as flat from the loading edge as with the Model Y.
Since the opening width, narrowest width, and loading edge height differ only minimally, they hardly influence daily usability: Both models are comparably practical in these respects.
Summary
For long or lengthwise-oriented cargo, the Tesla Model Y is clearly better suited. For a lower cargo floor with a well-usable recess for hidden or stacked items, the VW T-Cross is advantageous, although handling heavy loads may be somewhat less comfortable.
