Trunk comparison: Mercedes Benz CLA Shooting Brake vs VW ID.4

Biggest Differences (highlighted)

The most significant differences concern the usability of the cargo space: The Mercedes‑Benz CLA Shooting Brake offers 13% longer cargo floor length with the front seats upright and a significantly greater trunk depth (loading edge to trunk floor): +120% compared to the VW ID.4. Conversely, the VW ID.4 has a higher trunk opening (+13%) and a wider opening (+23%), which clearly facilitates loading and passing through tall and wide items.

Impact on Usability

Practically, this means: The CLA Shooting Brake is better suited for longer and deeper loads, especially when the rear seats are folded up – allowing longer, slender items (e.g., slats, skis, long boxes) to be accommodated more easily, and the greater depth creates more usable storage space below the loading edge, for example for stackable or deeper-lying goods.

On the other hand, the VW ID.4 excels at loading bulky, tall, or wide items: The 13% higher opening makes it easier to pass tall objects, and the 23% wider opening significantly eases loading wide furniture, strollers, or large moving boxes.

For frequent loading and unloading of cumbersome parts, the ID.4 is therefore more practical.

Smaller differences: When all seats are folded down, the CLA Shooting Brake is only about 5% longer than the ID.4 (not highlighted).

The narrowest interior width is slightly larger in the CLA (+4%), and the loading edge of the CLA is only 0.4 in higher than that of the ID.4 — these are minor practical factors compared to the differences mentioned above.

Brief conclusion: CLA Shooting Brake = more usable depth and longer cargo floor for elongated and stacked loads. ID.4 = significantly better handling of large, wide, and tall items due to higher and wider opening.
