Trunk comparison: Mercedes Benz GLC vs Peugeot 308 SW 3-row

Key Differences (only values >10% highlighted)

The cargo length shows a clear, configuration-dependent picture: With the seats folded down, the Mercedes‑Benz GLC offers a longer cargo area than the Peugeot (+11.8 in / +21%), making it more advantageous for very long items.

In the specified configuration with the first row of seats upright, the Peugeot 308 SW has a longer trunk (+5.9 in / +16%), which can mean more usable storage space in everyday use with this seating arrangement.

When all seats are upright, the GLC is clearly ahead and offers a significantly longer cargo area (+22.8 in / +166%), thus considerably more usable length when fully occupied.

Regarding opening and accessibility, the Peugeot scores: The height of the trunk opening is higher (+5.1 in / +17%), and the depth from the tailgate to the trunk floor edge is greater (+1.6 in / +300%), which facilitates loading tall or bulky items.

The Mercedes, on the other hand, has a significantly higher loading lip (+5.9 in / +27%), which makes lifting heavy loads more difficult but can be advantageous for some uses due to the higher ground clearance.

Impact on Usability

For transporting long items (e.g., laminate, slats, long pipes), the GLC is the more practical choice: with seats folded down and especially with all seats upright, it offers significantly more length.

For frequent loading and unloading of heavy luggage or bulky, tall items, the Peugeot is better suited: the higher opening and greater depth make stowing easier, and the lower loading lip reduces the effort required when lifting.

In summary: If you primarily need a long loading area (even when fully occupied), the Mercedes‑GLC is more favorable. If you often load tall or bulky parts or want to avoid frequent lifting, the Peugeot 308 SW offers the more practical loading geometry.
