Trunk comparison: VW Golf Wagon vs Durchschnitt SUV

Key Differences
The VW Golf Wagon offers a significantly longer loading length: with the seats folded down, the trunk is +10.2 in (16%) longer, and with the front seats upright even +9.4 in (28%) longer compared to the average SUV.
The depth of the trunk (distance from loading edge → trunk floor) is +2.4 in (120%) greater in the Golf Wagon.
At the same time, the loading edge of the average SUV is +5.5 in (23%) higher above the road than that of the Golf.
Smaller differences: the width at the narrowest point is only slightly larger in the SUV (+0.8 in / 2%), the opening width is +2.4 in (6%) wider in the SUV, and the opening height is only +0.4 in (1%) higher in the Golf — these values are not very relevant.
Impact on Usability
The extended loading area of the Golf Wagon significantly facilitates the transport of long items (e.g., slats, furniture parts, skis) — especially when the rear seats are folded down.
The greater depth means the cargo space has more "vertical depth": luggage sits lower and can be stacked better without protruding far beyond the loading edge.
Combined with the significantly lower loading edge in the Golf (SUV is +5.5 in higher), the Golf Wagon reduces the required lifting height when loading and unloading heavy items and makes loading more ergonomic.
The width advantages of the SUV are minimal (2–2.4 in) and only affect practical use with very wide items. The Golf's only 0.4 in greater opening height is negligible.
Overall, the Golf Wagon is better suited for linear and deep cargo as well as frequent, ergonomic loading and unloading, while the SUV offers no notable advantages in usable length or loading comfort — its slight width advantages hardly change the picture.
