Trunk comparison: Mercedes Benz GLC vs VW Tiguan Allspace

Key Differences

VW Tiguan Allspace offers a cargo area that is 7.5 in (≈20%) longer with the first row of seats upright than the Mercedes‑GLC. That means: with the seating configuration described in the info text as "first row upright," the Tiguan clearly gains usable cargo length.

The Mercedes‑Benz GLC has a trunk space that is 18.1 in (≈98%) longer with all seats upright than the Tiguan Allspace. With all seats in use, the GLC thus offers significantly more space behind the seats.

Implications for Usability

The 20% longer cargo area of the Tiguan in the mentioned seating setup makes it more practical for transporting long items without affecting front-seat passengers — e.g., slats, long boxes, or skis, when the front seats remain upright.

However, the Tiguan's loading edge is 2.4 in higher, meaning lifting heavy loads requires a bit more effort.

The significantly larger interior of the GLC with all seats upright makes it better suited when regularly transporting multiple passengers with luggage — such as families or trips with full occupancy.

Additionally, the GLC's trunk opening is slightly higher (+1.6 in) and the narrowest interior width is 3.9 in greater, making it easier to accommodate wider items behind the seats.

Other Differences (Briefly)

- With seats fully folded down, the Tiguan is reportedly 5.9 in (≈9%) longer — this difference is just under 10% and thus less pronounced. - The trunk depth (loading edge to floor) is the same. - The width of the trunk opening is 1.6 in larger on the Tiguan.

Practical Conclusion

Choose the Tiguan Allspace if you often need to carry long loads with the front bench largely upright. Choose the Mercedes‑GLC if you frequently travel with full occupancy and still want as much trunk space behind the seats or more interior width for wide items.
