Trunk comparison: VW Polo vs VW Tiguan

Key Differences
In terms of cargo volume and trunk shape, the Tiguan shows clear advantages: With the rear seats folded down, the Tiguan's cargo area is 13.4 in (25%) longer than the Polo's, and with the first row of seats upright, it is 8.7 in (33%) longer.
The Tiguan's trunk opening is also 6.7 in (18%) wider than the Polo's. In contrast, the Polo has a significantly greater depth between the loading edge and the trunk floor — this value is 2.8 in (700%) higher than the Tiguan's.
Smaller differences (no more than 10%) include: The height of the Tiguan's trunk opening is 2 in (7%) higher, the Tiguan's loading edge is 1.6 in (6%) higher above the ground, and the narrowest point in the trunk is only 0.4 in (1%) wider in the Polo.
Impact on Usability
The longer cargo areas of the Tiguan make it more practical for long or bulky items (e.g., slats, furniture parts, long suitcases) and increase overall capacity for family or vacation trips.
The significantly wider trunk opening on the Tiguan facilitates loading wide objects and reduces maneuvering or angle issues when loading.
The greater depth of the Polo means a deeper cargo floor relative to the loading edge. This can be useful for storing items deeper and thus more securely (less visible shifting), but increases the effort when lifting heavy items in and out.
Combined with the Polo's shorter length and narrower opening, this creates a clearer profile: The Polo is sufficient for everyday and city use with smaller/compact loads; the Tiguan is better suited for regular transport of long, wide, or bulky cargo.
