Trunk comparison: BMW iX1 vs Tesla Model Y

Key Differences

The Tesla Model Y offers significantly more cargo length: +12.6 in (≈20%) with seats folded and +8.3 in (≈23%) with the first row upright compared to the BMW iX1. The BMW iX1 has a greater depth between the loading edge and trunk floor (+0.8 in, indicated as 100% in the specs).

All other differences (trunk opening height +1.2 in/4%, loading edge height +0.8 in/3%, narrowest trunk width +2 in/5%, trunk opening width +3.1 in/8%) are under 10%.

Impact on Usability

Model Y — longer loading surface: The significantly greater cargo length makes the Model Y more practical for long items (e.g., furniture, slatted frames, skis, long boxes, or bicycles with mounted frames).

Those who frequently transport long goods or regularly use the interior as a transporter replacement clearly benefit from the Model Y.

iX1 — deeper loading surface and wider opening: The greater depth between the loading edge and trunk floor means volume can be used deeper down (useful for stackable or tall items that should be recessed close to the floor).

The slightly greater width at the narrowest point and the wider trunk opening make it easier to load wider/bulkier parts. A downside is the slightly higher loading edge above the road (+0.8 in), which makes heavy lifting a bit more difficult.

Practical Recommendation

If you frequently transport long items or need maximum cargo length: Tesla Model Y. If you prefer more usable depth and a wider opening for wider, tall, or bulky pieces (with an acceptable shorter loading length): BMW iX1.
