Trunk comparison: Ford S-MAX vs VW Caddy Wagon

Key Differences
The Ford S‑Max offers a significantly longer cargo space with the seats folded down: +32.3 in (+71%) compared to the VW Caddy Wagon. This makes the S‑Max clearly superior for long, flat, or bulky items (e.g., long furniture pieces, building materials, skis) and increases flexibility when transporting larger loads.
The trunk opening height is significantly greater in the VW Caddy Wagon: +8.3 in (+23%). This makes loading tall or bulky items easier and provides more vertical clearance when loading (e.g., large boxes, tall equipment, or furniture), especially when items need to be transported upright.
The trunk depth (loading edge to floor) is listed as +0.4 in (+50%) for the Ford S‑Max.
The percentage difference seems large, but the absolute difference is minimal (+0.4 in) and has little practical impact on usability — it can offer slightly more storage space directly behind the loading edge but is not a decisive factor.
Additional Differences and Practical Implications
With the first row of seats upright, the S‑Max is only slightly longer (+2 in / 5%) — hardly noticeable in daily use. The loading edge height is the same for both models, so the effort required to load cargo remains comparable.
The VW Caddy Wagon has a 10% wider width (+3.9 in) at its narrowest point and a slightly wider trunk opening (+2.8 in / 7%), which facilitates loading wider items, though these differences mostly fall below the 10% threshold and are moderate.
Conclusion: Those who frequently transport long, flat, or bulky items will benefit more from the Ford S‑Max (longer cargo space with folded seats). Those who often load tall or bulky cargo or value a higher opening for easier loading will find the VW Caddy Wagon the more practical solution.
