Trunk comparison: Mercedes Benz GLB vs Peugeot 5008

Comparison of trunk dimensions for the Mercedes Benz GLB and Peugeot 5008

Summary of the Biggest Differences

The most noticeable differences concern the cargo length in certain seating configurations and the cargo depth. Highlights include:

GLB: +24 in (179%) longer cargo length with upright seats compared to the 5008.
GLB: +4.3 in (1100%) greater cargo depth (loading edge → trunk floor).
5008: +3.9 in (11%) longer cargo length when the first row of seats is upright compared to the GLB.

What Are the Practical Implications?

GLB — Advantages in everyday use and with full occupancy:
Thanks to the significantly longer cargo length with upright seats (+24 in), the GLB is much better suited when transporting a lot of luggage with multiple passengers at the same time (e.g., family trips with luggage in the rear).

The significantly greater cargo depth (+4.3 in) increases usable volume, makes storing taller or stacked items easier, and allows better storage of boxes or larger pieces of luggage.

Drawback/practicality: greater depth can make lifting heavy items in and out somewhat more difficult because the floor sits deeper in the vehicle.

5008 — Advantages with long or wider loads and folded seats:
The 5008 offers slightly more cargo length (+3.9 in) in the configuration with the first row upright, which is useful when transporting longer items without adjusting the front seats (e.g., skis, long packages).

Overall, the 5008 is slightly longer (+4.3 in / 6%) with the cargo area fully folded down, providing a bit more space for pure freight transport. Additionally, the 5008 offers somewhat more width at the narrowest point and at the opening (moderate differences), which simplifies loading wider items.

Practical Recommendation

If you regularly travel with multiple occupants and larger luggage volume or often transport tall/stacked cargo, the Mercedes‑GLB is the more practical choice due to its significantly larger usable cargo space and depth.

If you more frequently transport long items without adjusting the front seats or prefer a slightly wider opening and usable width, the Peugeot 5008 is more advantageous.
