Trunk comparison: Opel Astra Wagon vs Peugeot 3008

Key Differences
Both models are similar in many dimensions but show two significant differences in cargo space: The depth of the trunk (loading edge to trunk floor) is 3.5 in (≈450 %) greater in the Peugeot than in the Opel.
Additionally, the loading edge of the Peugeot sits 8.3 in (36 %) higher above the road than in the Opel Astra Wagon. All other stated differences (length and width values) are under 10 % and thus comparatively minor.
Impact on Usability
The significantly greater depth in the Peugeot means the cargo space forms a deeper basin: bulky or tall items can be recessed much "deeper" into the space, heavy loads sit lower and are less visible inside the vehicle.
This helps when transporting voluminous but not necessarily heavy parts and increases usability for irregularly shaped cargo.
However, the higher loading edge of the Peugeot makes loading more physically demanding: heavy luggage, boxes, or shopping bags must be lifted higher, making loading less convenient and more straining on the back.
The Opel Astra Wagon with its lower loading edge is more ergonomic for frequent loading and unloading of heavy items and is therefore often more practical in everyday use.
Since length and width differences (e.g., Opel +3.1 in with front seats upright, Peugeot +0.4 in with seats folded down, Opel +3.1 in narrowest width, Opel opening width +1.2 in) are under 10 %, they have little impact on daily usability.
The decisive choice criteria are therefore: do you prefer easier, back-friendly loading (Opel) or a deeper cargo space with more "basin" volume (Peugeot)?
