Trunk comparison: Jeep Renegade vs Mercedes Benz GLC

Key Differences
The Mercedes‑Benz GLC offers significantly more cargo length: with the seats folded down, the trunk is +8.7 in (14%) longer and with the first row upright, the trunk is +6.3 in (21%) longer than the Jeep Renegade.
Additionally, the narrowest trunk width in the GLC is +5.5 in (15%) larger and the width of the trunk opening is +4.7 in (12%) larger than in the Renegade.
In contrast, the Jeep Renegade has a higher trunk opening: the opening height is +5.1 in (17%) higher than the GLC, and the depth from the loading edge level to the trunk floor is +5.5 in (1300%) greater in the Renegade than in the GLC.
Although the Renegade's loading edge is slightly higher above the road (+2 in / 7%), this value is below the 10% threshold and is not highlighted here.
Impact on Usability
The longer interior dimensions and greater widths of the GLC make it more practical for long or wide cargo: long items (e.g., slats, furniture boards, skis) fit more easily into the vehicle, and wide items can be more easily loaded through the larger opening and stored at the widest point of the trunk.
For luggage of individual travelers, strollers, or bulky boxes, the GLC offers more usable floor space overall.
The Renegade scores in vertical usability: the higher trunk opening and especially the significantly greater depth between the loading edge and trunk floor provide more vertical space or a lower loading floor.
This is advantageous when stacking boxes, transporting taller items, or when the cargo needs to be practically "recessed" deeper into the vehicle. However, the slightly higher loading edge makes lifting heavy loads marginally more strenuous than in the GLC.
Conclusion
In short: Those who need longer and wider cargo or generally a flatter, easier-to-load cargo volume have the practical advantage with the GLC. Those who prefer more vertical storage space and a deeper loading floor for stackable or tall items will find better utility in the Renegade — at the expense of length/width.
