Trunk comparison: BMW 3 Series Touring vs Tesla Model Y

Key Differences (>10%)

The Tesla Model Y offers a 7.5 in (≈11%) longer cargo area with seats folded down and with the front seats upright a 4.3 in (≈11%) greater usable length than the BMW 3 Series Touring. At the same time, the Tesla's loading edge is 3.9 in (≈17%) higher above the ground.

Impact on Usability

The greater usable length in the Tesla specifically means more room for long items (e.g., slats, skis, furniture parts) and more flexible loading with the rear seats folded down. Everyday luggage and bulky but elongated cargo can be accommodated more easily in the Model Y.

The higher loading edge of the Tesla, however, makes loading and unloading more strenuous, especially for heavy or low items (shopping crates, strollers, toolboxes): more lifting effort and less back-friendly.

The BMW has only marginal advantages in opening height (+1.2 in) and trunk depth (+0.4 in), which are hardly noticeable in everyday use but can be somewhat more comfortable when lifting particularly tall items with a low loading edge.

The narrowest width of both trunks is the same, the opening width differs by only ~0.4 in in favor of the Tesla and is therefore negligible.

Conclusion: Those who frequently transport longer items or need maximum cargo space benefit from the Tesla Model Y.

Those who often lift heavy loads or require more back-friendly loading have slight advantages with the BMW due to the lower loading edge. For average everyday use, the differences in width and opening are hardly relevant.
