Trunk comparison: BMW X1 vs Tesla Model Y
Key Differences
The clearest advantage of the Tesla Model Y lies in the length of the cargo space: the Model Y offers +11.8 in (18%) with folded seats and +8.3 in (23%) with the first row upright more depth than the BMW X1. In contrast, the BMW X1 has a notable depth geometry in the trunk: the distance from the loading edge to the trunk floor is +1.2 in (200%) greater in the X1 than in the Model Y.
All other values — opening height (+1.2 in / 4%), loading edge height (+0.4 in / 1%), narrowest width (+2.4 in / 6%), opening width (+2.4 in / 6%) — are under 10% difference and thus secondary.
Implications for Usability
The longer dimensions of the Tesla bring noticeable advantages when transporting long items: with folded or even upright rear seats, bulky, longitudinally placed loads (e.g., long furniture parts, boards, skis, or bicycles with the front wheel removed) can be accommodated more easily.
In everyday situations, this means more flexibility for individual pieces that need to be loaded lengthwise.
The greater depth in the BMW X1 (loading edge → trunk floor) changes the shape of the cargo space: the deeper trunk floor creates more "wave depth," which can improve stacking boxes and volume for taller loads in the rear area.
At the same time, a lower loading floor can be less practical when loading heavy items because a greater height difference must be overcome when lifting in; combined with the slightly higher loading edge of the X1 (+0.4 in), this slightly increases the effort required for lifting.
The somewhat greater width and opening dimensions of the BMW X1 are practical when wide items need to be loaded crosswise or when loading bulky boxes — however, these advantages are moderate since the differences are under 10%.
In short: Those who frequently transport long items crosswise/lengthwise or want maximum longitudinal cargo space will benefit more from the Tesla Model Y.
Those who prefer a deeper cargo well for stacked loads and a slightly wider opening will find advantages in the BMW X1 but must accept a slightly increased lifting effort when loading.
