Trunk comparison: Mercedes Benz GLC vs Skoda Elroq

Key Differences
The most noticeable difference lies in the loading length with the first row of seats upright: the Mercedes-Benz GLC offers 5.1 in (16%) more length than the Škoda Elroq. With the seats folded down, however, the GLC is only 3.1 in (5%) longer.
The width of the trunk at its narrowest point is 3.9 in (10%) greater in the GLC, and the width of the trunk opening is 2.8 in (7%) wider. The height of the trunk opening is the same in both models.
The depth (loading edge to trunk floor) is 0.4 in greater in the Elroq (practically negligible), while the loading edge of the GLC is 0.8 in higher above the road (about 3%).
Impact on Usability
The 16% longer cargo space with the first row of seats upright makes the GLC more practical for transporting long items when the rear seats need to be used (e.g., skis, slats, long boxes). The greater minimum width and the slightly wider opening also make it easier to load wider or irregularly shaped items in the GLC.
The Elroq has no significant advantages in volume but offers a slightly lower loading edge and 0.4 in greater depth, which minimally eases handling very heavy or flat loads.
Overall, the Elroq tends to be practical for regular shopping and occasional loads, while the GLC remains better suited for longer or wider cargo due to its greater usable length and width.
Conclusion
For regular transport of long items with occupied seats, the Mercedes-Benz GLC is the better choice. Those who primarily focus on easy loading and unloading of heavy items and do not transport long loads will find the Škoda Elroq a solid, modestly different alternative.
