Trunk comparison: BMW 3 Series Touring vs Tesla Model 3

Key Differences

The Tesla Model 3 offers a slightly longer cargo area with the seats folded down (+4.7 in / +7%) and also a slight length advantage with the first row of seats upright (+2.8 in / +7%) compared to the BMW 3 Series Touring.

The width of the trunk at its narrowest point and the width of the trunk opening are the same in both models.

The trunk opening of the BMW 3 Series Touring is significantly higher than that of the Tesla (+7.9 in / +38%). This means more vertical space for loading tall or bulky items through the opening.

The depth of the trunk (distance from loading edge to trunk floor) is significantly greater in the Tesla (+3.9 in / +1000%). This indicates a much deeper cargo well in the Model 3, thus more vertical space inside the trunk.

The loading edge of the Tesla is higher above the ground (+2.8 in / +12%). This means more lifting effort is required when loading and unloading compared to the BMW.

Impact on Usability

Practically, the following advantages and disadvantages arise:

• BMW 3 Series Touring: The significantly higher trunk opening makes it easier to load bulky or tall cargo from above. The lower loading edge facilitates lifting heavy items into the vehicle. For users who frequently load large, tall items (e.g., boxes, plants, furniture parts), the Touring is more comfortable for everyday use.
• Tesla Model 3: The greater trunk depth provides more usable storage space in the cargo well, especially for lower-lying or elongated items. However, the higher loading edge requires more strength when lifting, and the lower opening height makes it harder to load very tall items. For users who transport a lot of flat or long cargo (e.g., skis, long boxes), the Model 3 is advantageous; for frequently loading heavy, tall, or bulky items, the BMW is more practical.
• The slight length advantages of the Tesla (≈7%) are measurable but only relevant in everyday use for very long items; they do not compensate for the limitations caused by the lower opening height and higher loading edge.

Conclusion

If heavy or very tall items are frequently loaded, the BMW 3 Series Touring is more comfortable due to the larger opening height and lower loading edge.

If instead, lower-lying, elongated storage and overall slightly more cargo volume with folded seats are the priority, the Tesla Model 3 offers advantages — albeit at the cost of higher lifting effort when loading and a smaller opening height.
