Trunk comparison: Audi A6 Avant vs Tesla Model Y

Key Differences
The Audi A6 Avant offers overall slightly larger dimensions in the cargo space: with the seats folded down, the trunk of the A6 is 0.8 in (≈1%) longer, and with the first row of seats upright, it is 2.4 in (≈5%) longer. The trunk opening is about 1.6 in (≈6%) higher in the A6, the narrowest width of the cargo area is about 2 in (≈5%) larger, and the width of the opening is approximately 1.2 in (≈3%) wider than in the Model Y. However, the Tesla's loading edge is about 2.4 in (≈9%) higher above the ground than the Audi's. Particularly notable is the depth of the trunk (distance from loading edge to trunk floor):

Implications for Usability
The greater depth of the A6 practically means more space below the loading edge, i.e., more vertical volume near the floor; this makes it easier to store flat or stackable items and increases the usable trunk capacity at the same exterior length. Due to the lower loading edge height in the Audi (2.4 in lower), loading heavy or bulky items is generally easier — less lifting upwards than in the Tesla. The slightly longer and wider dimensions of the A6 (although only in the mid-single-digit percentage range) marginally improve the packing of longer items and usage when fully loaded, while the Model Y, due to the higher loading edge and lower floor depth, tends to be somewhat less comfortable for frequent loading and unloading of large or heavy loads. Overall, the A6 offers a more practical loading geometry for users who often work with differently sized and sometimes heavy items; the Model Y remains compact but may have disadvantages in handling heavy loads and utilizing floor volume.
