Trunk comparison: Mercedes Benz CLA Shooting Brake vs Seat Leon

Key Differences

In terms of usable cargo space, the Mercedes-Benz CLA Shooting Brake is significantly longer inside: with the rear seats folded down, the trunk is +11.4 in (19%) longer, and with the front seats upright, it is +9.1 in (28%) longer than in the SEAT Leon.

The narrowest interior width also favors the CLA Shooting Brake clearly: the tightest spot is +9.4 in (30%) wider in the CLA.

On the other hand, the SEAT Leon has a larger trunk opening and more space in front of the loading edge: the opening height is +3.5 in (13%) higher on the Leon, and the depth from the loading edge to the trunk floor is +1.2 in (14%) greater.

The loading edge height is the same for both models; additionally, the Leon has a +8.7 in (25%) wider trunk opening than the CLA.

Impact on Practical Usability

The longer interior dimensions of the CLA Shooting Brake make it more suitable for long items (e.g., slats, long boxes, unfolded furniture parts, or long skis): with +19–28% more length, these can be transported more easily and usually without repositioning.

The greater narrow interior width in the CLA (+30%) means that wider loads that need to be placed deep in the trunk fit more easily.

The SEAT Leon scores points for loading comfort with tall and bulky items: the higher opening (+13%) and the greater depth in front of the loading edge (+14%) make it easier to slide in and stand up bulky or tall cargo and provide more space immediately behind the loading edge.

The significantly wider opening of the Leon (+25%) makes it easier to insert wider items through the opening, even though the interior is narrower at the tightest spot.

Practical conclusion: For longer and wider cargo, the CLA Shooting Brake is more advantageous. For frequent loading of bulky, tall, or hard-to-access items (easier lifting in, wider opening), the SEAT Leon is more practical for everyday use.
