Trunk comparison: Opel Grandland vs VW Passat Wagon

Key Differences
The VW Passat Wagon offers significantly more cargo length: it is 12.6 in (19%) longer with the seats folded down and 9.4 in (27%) longer with the first row of seats upright than the Opel Grandland.
Two features stand out for the Opel: the trunk depth (loading edge to trunk floor) is 2.8 in (78%) greater and the loading edge is 5.5 in (22%) higher above the road than on the Passat.
Smaller differences include a 0.8 in (3%) higher trunk opening on the Grandland and a 1.2 in (3%) wider trunk opening on the Grandland; the narrowest interior width is the same for both models.
Impact on Usability
The longer cargo area of the Passat makes it more practical for long or bulky items like furniture parts, slatted frames, skis, or longer boxes—especially when the seats are folded down. Those who regularly transport long loads or need a flatter, longer cargo space with folded seats clearly benefit from the Passat.
The Grandland scores with its significantly greater trunk depth measurement: more space between the loading edge and floor means more usable interior height in the cargo area, which facilitates stacking and accommodating tall items within the cargo space.
However, the 5.5 in higher loading edge makes loading and unloading more difficult, especially with heavy or bulky loads; the higher lift over the threshold can make handling more cumbersome.
Width bottlenecks are identical at the narrowest point in both cars, so wide items must be checked equally for both models. The small differences in opening height and width (each about 3%) are hardly noticeable in everyday use.
