Trunk comparison: Ford S-MAX vs Opel Astra Wagon

Key Differences

The Ford S‑Max offers a significantly longer cargo floor when the seats are folded down: +7.9 in (11%) longer than the Opel Astra Sports Tourer. The Astra stands out particularly for the depth between the loading edge and the trunk floor: +4.3 in (367%) compared to the S‑Max.

Impact on Usability

The longer cargo area of the S‑Max with folded seats makes it better suited for long items (e.g., furniture boards, skis, long boxes) and for flexible use when the rear seat bench needs to be fully used or folded flat.

Due to the greater length, bulky, longer loads can be accommodated more easily and space-efficiently.

The greater depth of the Astra (larger distance loading edge → trunk floor) means more vertical cargo space below the loading edge. This can be advantageous when bulky or tall items need to be placed low or when more volume is needed in the lower area.

At the same time, a deeper cargo floor increases the handling difficulty of heavy items when loading and unloading (greater lever arm)—especially since the loading edge of the Astra sits somewhat higher above the road, which makes lifting additionally harder.

Side note (not as a >10% highlight): The S‑Max has a slightly higher trunk opening (+3.1 in, 9%) and a minimally larger width at the narrowest point (+0.4 in, 1%).

The Astra has a slightly wider opening (+0.4 in, 1%) and a +1.6 in (7%) higher loading edge above the road. These smaller differences only marginally affect everyday usability but can be noticeable when handling heavy luggage or loading bulky items.
