Trunk comparison: Ford Focus vs Mercedes Benz GLB

Key Differences

The Mercedes-Benz GLB offers significantly more loading length: with the seats folded down, the trunk is 8.7 in (+14%) longer and with the first row of seats upright, the trunk is 7.1 in (+23%) longer than the Ford Focus.

This makes the GLB clearly better suited for long items. The GLB also has a slightly larger opening and width (+2.4 in and +1.6 in respectively) and a trunk opening height that is 3.1 in (10%) higher – however, these values are at or just below the 10% threshold.

The Ford Focus scores with its internal depth: the depth from the loading edge to the trunk floor is 2.4 in (+50%) greater in the Focus than in the GLB. This creates more vertical space in the cargo area and changes how cargo lies and is secured.

Impact on Usability

Due to the longer loading surface, the GLB is more practical when regularly transporting long or bulky items (e.g., slats, furniture parts, skis). The slightly larger opening makes it easier to load and maneuver longer parts. The higher opening height of the GLB (by 3.1 in) also helps with tall items.

The deeper trunk floor in the Focus means more usable vertical volume: crates and stacks can be placed lower, and smaller items lie more securely in the "deep well." Because of the lower loading edge height relative to the road (the Focus has a loading edge 1.2 in lower), loading and unloading heavy loads is somewhat easier than in the GLB.

Practical conclusion: Those who often transport long or bulky parts will find the GLB the more practical solution. Those who frequently carry stacked goods, crates, or prefer easier, more ergonomic access during daily loading and unloading will benefit more from the Focus.
