Trunk comparison: BMW 3 Series Touring vs VW ID.3

Comparison of trunk dimensions for the BMW 3 Series Touring and VW ID.3

Key Differences

The BMW 3 Series Touring offers a significantly longer loading area: with the seats folded down, the trunk of the BMW is +8.7 in (14%) longer, and with the first row of seats upright, it is even +8.3 in (27%) longer than the VW ID.3. The VW ID.3, on the other hand, has a considerably greater depth between the loading edge and the trunk floor: this is +5.9 in (1500%) larger in the ID.3. Additionally, the loading edge of the ID.3 sits +6.7 in (28%) higher above the road than in the BMW.

Smaller differences under 10% are: the trunk opening of the ID.3 is 1.2 in (4%) higher, the narrowest trunk width in the ID.3 is 2.4 in (6%) larger, and the width of the trunk opening in the BMW is 1.6 in (4%) larger.

Impact on Usability

The greater loading length of the BMW makes it more practical for long items (e.g., furniture parts, skis, or long boxes) and for flexible use with folded seats. If bulky, longer cargo is regularly transported, the BMW is noticeably more advantageous in everyday use.

The significantly greater depth in the ID.3 means that the cargo is "recessed" deeper into the vehicle floor — this increases the usable vertical height under the loading edge and can hold luggage more stably and discreetly.

At the same time, the higher loading edge makes lifting heavy or bulky items into the trunk considerably more strenuous.

Taken together, this means: the ID.3 is well suited if items are to be stored securely and deeper or if appearance/storage is important (when willing to accept the higher loading edge), but is less suitable if heavy or long parts need to be lifted frequently from the floor.

The differences in width and opening height are minor and only marginally affect everyday practicality.

In short: those who prefer longer items and easy loading and unloading are better served by the BMW 3 Series Touring; those who want a deeper cargo well and concealed, lower loading (when willing to accept the higher loading edge) will find advantages in the VW ID.3.
