Trunk comparison: Mercedes Benz GLB vs VW Touran

Key Differences

The Mercedes‑Benz GLB offers a significantly larger trunk with all seats upright: +24 in (+179%) compared to the VW Touran. Furthermore, the trunk depth (distance from loading edge to trunk floor) is considerably greater in the GLB: +4.3 in (+1100%).

The loading edge of the GLB is also higher above the road: +3.9 in (+16%). All other measured values fall within smaller deviations (±6% or less) – trunk width is the same, and with seats folded down, the difference is only +0.8 in (≈1%) in favor of the Touran.

Implications for Usability

Due to the significantly larger volume with seats upright and the greater trunk depth, the GLB is better suited for everyday use with full occupancy: it accommodates bulky or taller items better and offers more usable cargo volume overall without folding the seats.

The greater depth also means that items can slide further "into" the trunk, which is advantageous when transporting longer or irregularly shaped loads.

In contrast, the higher loading edge of the GLB makes loading and unloading heavy items more difficult compared to the Touran: lifting must be done higher, which makes handling heavy cargo less comfortable.

Since widths and opening dimensions are very similar, there are no advantages or disadvantages when loading wide items.

Practically speaking: those who frequently travel fully occupied and regularly carry bulky or tall cargo benefit more from the GLB.

Those who often need to load heavy items conveniently close to the ground or primarily require a lot of cargo space with folded seats will find no major disadvantages in the Touran and benefit from a slightly lower loading edge.
