Trunk comparison: Ford S-MAX vs Opel Astra Wagon

Key Differences (>10%)

The biggest differences mainly concern the cargo area and opening: The Ford S‑Max has a +12.6 in (19%) longer trunk with the seats folded down than the Opel Astra Wagon. The height of the trunk opening is +5.9 in (19%) higher on the S‑Max.

Additionally, the depth of the trunk (loading edge to trunk floor) is only +0.4 in greater on the S‑Max in absolute terms, but this corresponds to a stated +50% and means a significantly different proportion in the cargo space.

Impact on Usability

These differences significantly affect everyday usability: The longer cargo area with folded seats makes the S‑Max clearly more suitable for long items (slats, furniture boards, skis, garden tools).

The greater opening height makes loading and unloading tall or bulky items easier and reduces the risk of hitting the roof edge when lifting.

The greater depth from the loading edge floor creates more usable interior height directly behind the loading edge, which helps when storing tall packages or stacking — even if the absolute difference is small.

Smaller advantages of the Astra Wagon: The narrowest trunk width is +2.4 in larger on the Astra, so very wide, rigid items tend to fit more easily at the tightest point.

The loading edge is slightly higher on the Astra (+0.8 in), which means slightly more effort when lifting heavy loads, but this plays a minor role in practice. With the first row of seats upright, the S‑Max has only a slight advantage (+2 in, 5%).

Conclusion: Those who often transport long or tall loads noticeably benefit from the S‑Max. The Astra Wagon can offer an advantage with very wide items at tight spots; otherwise, its usability is generally less geared toward bulky/tall transports.
