Trunk comparison: BMW X1 vs VW ID.3

Comparison of trunk dimensions for the BMW X1 and VW ID.3

Key Differences (highlighted values >10%)

The most noticeable differences concern the usable trunk length with the first row of seats upright, the width of the trunk opening, and the trunk depth (loading edge to floor).

The BMW X1 offers +4.3 in (14%) longer trunk when the first row is upright, and a +4.3 in (11%) wider trunk opening than the VW ID.3. The VW ID.3 has a trunk depth (loading edge to trunk floor) that is +5.1 in (433%) greater than the BMW X1. Smaller differences under 10% are: with folded seats, the BMW X1 has +4.3 in (7%) more length; the trunk opening height of the ID.3 is +1.2 in (4%) higher; the loading edge of the ID.3 is +2.4 in (8%) higher; the narrowest width is the same for both models.

Impact on Usability

BMW X1 — Advantages: The longer cargo floor with the rear bench upright (+14%) and the wider opening (+11%) make the X1 more practical for long and wide items (e.g., furniture parts, boards, long boxes, skis) because these need to be tilted or turned less.

In everyday situations involving frequent transport of bulky, flat, or long loads, the X1 is therefore more flexible.

VW ID.3 — Advantages and Limitations: The significantly greater trunk depth (+433%) indicates a deeper cargo well. This creates additional storage space below the loading edge and can be advantageous for stackable or taller items that fit into the recess, as well as for hiding luggage.

However, the loading edge on the ID.3 is somewhat higher (+2.4 in, 8%), which can make lifting heavy loads a bit more difficult. The greater depth may also mean that flat, long items lie less evenly or are more prone to sliding, depending on the shape of the cargo floor.

Practical Conclusion: For regular transport of long or wide parts, the BMW X1 tends to be more suitable.

Those who prefer more variable cargo depth and hidden storage space (e.g., for boxes, stackable loads, or items to be "sunk" into a cargo well) have advantages with the VW ID.3 — but at the cost of a slightly higher loading edge and narrower opening width.
