Trunk comparison: Mercedes Benz GLB vs Skoda Karoq

Key Differences

The Mercedes‑Benz GLB offers significantly more cargo length: with the seats folded down, the trunk is 8.3 in (13%) longer, and with the first row upright, even 7.5 in (25%) longer than the Škoda Karoq.

In contrast, the Karoq has a notably deeper cargo area between the loading edge and trunk floor: here it is 1.2 in (25%) deeper than the GLB.

Smaller differences (Karoq opening height +1.6 in/5%, higher loading edge of the GLB +1.6 in/6%, narrowest width at the GLB +1.6 in/4%, opening width at the GLB +0.8 in/2%) exist but are not as defining as the three mentioned values.

Impact on Usability

The longer cargo floors of the GLB mean a clear advantage when transporting long items like skis, sheet goods, or bulky furniture: longer cargo length offers more flexibility both with folded seats and full seating.

Due to the slightly greater narrowest width and marginally larger opening width, wider luggage can also be placed more easily.

The deeper trunk of the Karoq plus the slightly higher opening height ensure that taller or bulkier loads can be better accommodated and stacked; at the same time, loading tends to be more ergonomic because the loading edge is lower (the GLB’s loading edge is about 1.6 in higher).

For frequent lifting of heavy items, the Karoq is thus more practical, while the GLB clearly has the advantage for long or extended cargo.

Conclusion: Those who regularly transport long items or need more usable cargo length will likely choose the GLB. Those who often carry heavy, tall, or stacked loads and value easier lifting benefit more from the Karoq.
