Trunk comparison: Mercedes Benz CLA Shooting Brake vs Opel Astra Wagon

Key Differences (main deviations >10%)

In practical use, four differences stand out: The trunk opening height is +5.5 in (≈20%) higher in the Opel, the width of the trunk opening is +7.9 in (≈23%) larger in the Opel.

The interior depth between the loading edge and trunk floor is +3.1 in (≈57%) greater in the Mercedes, and the loading edge of the Mercedes is +5.5 in (≈23%) higher above the ground.

All other deviations (e.g., trunk length with front seats upright +1.6 in / 4%, width at the narrowest point +1.2 in / 3%) are below the 10% threshold and thus practically marginal.

Impact on Usability

Opel Astra Sports Tourer: The significantly higher opening height and larger opening width make loading tall or wide items easier. Large boxes, furniture pieces, or bulky sports equipment can be lifted more easily into the car and maneuvered through the wide opening.

Additionally, the lower loading edge reduces the lifting and maneuvering effort required when loading and unloading, which is noticeable in everyday use (e.g., groceries, strollers, heavy suitcases).

Mercedes-Benz CLA Shooting Brake: The greater depth between the loading edge and trunk floor creates more "free space" inside the trunk, allowing cargo to be stored deeper and thus more securely (less shifting with short loads).

However, the loading edge is significantly higher above the ground, making it harder to lift heavy loads into the trunk. Combined with the greater interior depth, accessing deep areas can be more difficult and usually requires more strength or frequent squatting.

Practical conclusion: For frequent loading and unloading of heavy, wide, or tall items, the Opel Astra Sports Tourer is more ergonomic and flexible in everyday use.

The Mercedes CLA Shooting Brake offers advantageous interior space conditions for deeper stored cargo but pays for these benefits with a higher loading edge and thus more difficult handling.

For occasional transport of bulky items, the Opel is usually the more practical choice; when deeper, securely tie-down cargo space is needed, the Mercedes can score points.
