Trunk comparison: Opel Astra Wagon vs Peugeot 208

Key Differences
The Opel Astra Sports Tourer offers significantly more cargo length: +18.5 in (36%) with the seats folded down and +13.8 in (52%) with the front row upright compared to the Peugeot 208. The trunk opening of the Astra is higher and wider: +3.9 in (13%) opening height and +8.3 in (24%) opening width.
The Peugeot has a greater interior "depth" from the loading edge level to the trunk floor by +1.6 in (29%), and the loading edge of the Peugeot is +3.9 in (16%) higher above the ground. The narrowest trunk width differs by only 6% in favor of the Astra (not >10%).
What are the implications for usability?
More length and a significantly larger opening in the Astra mean: easier transport of long items (slats, furniture, skis), better stacking, and easier loading of bulky objects thanks to the wider and higher opening.
The lower loading edge of the Astra reduces the effort required to lift heavy cargo and makes sliding items in easier.
The Peugeot does offer a greater depth from the loading edge level to the trunk floor (more "well" depth), but this is offset by the significantly higher loading edge above the ground — in practice, lifting and loading remain more strenuous, and the narrower opening width as well as shorter loading length considerably limit the transport of long or wide items.
For everyday tasks, smaller shopping, and urban use, the Peugeot is sufficient; for regular transport of long, wide, or bulky loads, the Astra is clearly advantageous.
