Trunk comparison: Mazda Mazda CX-5 vs Mercedes Benz CLA Shooting Brake

Key Differences

Three differences stand out clearly from the measurements: The height of the Mazda's trunk opening is 3.1 in (11%) higher than the CLA's, the depth of the trunk (loading edge to trunk floor) of the Mercedes is 6.7 in (340%) greater, and the width of the Mazda's trunk opening is 7.5 in (22%) wider.

Smaller differences: the CLA offers +3.1 in (5%) more cargo length with folded seats and +3.9 in (10%) more with the first row upright; the Mazda's loading edge is only 0.4 in (1%) higher above the ground; the narrowest interior width is the same in both models.

Impact on Usability

The greater opening height and wider opening of the Mazda make loading bulky, tall, or wide items significantly easier: boxes, suitcases, strollers, or items with a larger cross-sectional area can be lifted in more easily, and access to the cargo space is better.

The wider opening also reduces the risk of bumping into the edge.

The significantly greater depth in the CLA (loading edge → trunk floor) indicates more usable vertical volume or that items can "fall" further in and lie deeper in the cargo space.

This is advantageous when stacking a lot of luggage or accommodating longer items. At the same time, very deep loads can be harder to reach and make lifting heavy items in and out more difficult.

The slightly longer cargo length of the CLA (up to 8–3.9 in more depending on seat position) supports transporting longer items but is only a moderate advantage. The practical loading edge height differs little and is negligible in daily use.

Conclusion: Those who frequently load wide or tall items and value easy access benefit more from the Mazda CX-5. Those who need deeper cargo volume and somewhat more interior length for stacking or longer loads are better served by the Mercedes-Benz CLA Shooting Brake.
