Trunk comparison: Mercedes Benz CLA Shooting Brake vs Tesla Model Y
Key Differences (highlighted: >10%)
Significantly greater depth in the CLA Shooting Brake: The Mercedes‑CLA Shooting Brake has 8.7 in (2100%) more depth between the loading edge and trunk floor than the Tesla Model Y.
Wider narrowest interior width in the CLA Shooting Brake: At its narrowest point, the trunk of the CLA Shooting Brake is 3.9 in (11%) wider than that of the Model Y.
Wider trunk opening in the Model Y: The opening of the Tesla Model Y is 5.5 in (16%) wider than that of the CLA Shooting Brake.
What this means for usability
The CLA Shooting Brake offers more interior space in depth and at the narrowest point. Practically, this means: bulky or long items that must pass through internal tight spots are more likely to fit in the Mercedes, and the greater depth allows volume to be utilized "deeper" (e.g., stacking below the loading edge).
Downsides include poorer ergonomics when loading and unloading: items must be lifted higher or lifted out of a deeper recess, handling heavy loads becomes more strenuous, and removing large items can be more cumbersome.
The Tesla Model Y scores with its significantly wider opening. This greatly simplifies loading bulky, wide items — less maneuvering, easier sliding of large boxes or furniture.
Combined with the lower loading edge (a smaller difference but advantageous), handling during loading is more ergonomic, and everyday shopping or strollers can be lifted in and out more easily. The rear overall length with folded seats is slightly longer in the Model Y but only has a moderate effect.
Summary
For frequent loading of wide parts and better ergonomics when handling heavy items, the Tesla Model Y is usually more practical (wider opening, lower loading edge).
Those who need more interior space at tight spots and in depth — i.e., longer, bulky items that should lie deeper in the cargo area — benefit more from the Mercedes‑CLA Shooting Brake but accept a higher effort when loading and unloading.
