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

Key Differences

The biggest differences concern dimensions that exceed 10% significantly: The Mercedes‑Benz CLA Shooting Brake has a trunk well that is 7.9 in (≈1000%) deeper (loading edge → trunk floor) and a loading edge that is 6.3 in (27%) higher above the road.

In contrast, the Opel Astra Wagon offers a trunk opening that is 7.1 in (21%) wider.

Impact on Usability

These differences have concrete consequences in everyday use:

• Mercedes — deep interior well (+7.9 in): More usable volume below the loading edge, useful for bulky or irregularly stackable items, as there is more space under the lip. However, lifting heavy items in can be more difficult because they must be lifted over the higher loading edge.
• Mercedes — higher loading edge (+6.3 in): Increases the effort required when loading (especially with heavy loads or strollers). For users who frequently load and unload heavy items, the Astra with its lower loading edge is more comfortable.
• Opel — wider opening (+7.1 in): Significantly easier to load wider items (e.g., furniture parts, boxes, sports equipment). The larger opening compensates in many situations for the somewhat smaller volume below the loading edge.

Less significant differences (below or around 10%): When the rear seats are folded down, the Mercedes is 4.7 in (7%) longer; with the front seat upright, the Astra is 0.4 in (1%) longer.

The height of the trunk opening is 2.8 in (10%) greater on the Astra — these values have less practical impact than the three differences mentioned above.
