Trunk comparison: Mazda Mazda CX-60 vs Mercedes Benz GLE

Key Differences
The most noticeable difference is the 8.3 in (12%) longer cargo length with folded seats in the Mercedes-Benz GLE. This is the only value with more than a 10% difference and thus undoubtedly the most practically relevant advantage of the GLE.
Other Differences (under 10%)
With the first row of seats upright, the GLE offers a 2.8 in (7%) longer cargo area. The height of the trunk opening is 2 in (7%) greater in the GLE, and the loading edge is 1.2 in (4%) higher.
The depth of the trunk (loading edge to floor) is the same in both models, and the narrowest width and the width of the opening differ by only 0.4 in (≈1%) each.
Impact on Usability
The 8.3 in longer cargo length with folded seats makes the GLE significantly better suited for transporting long items (e.g., slats, boards, furniture parts, skis) without having to load diagonally or partially dismantle the rear seat.
Those who frequently transport long or bulky goods will noticeably benefit from the GLE.
The moderate increase in cargo length with the seats upright (+2.8 in) and the higher opening (+2 in) slightly improve storing tall items but are not major everyday advantages.
The 1.2 in higher loading edge of the GLE can make lifting heavy items somewhat more strenuous, while the same depth and nearly identical widths mean that small to medium-sized items fit similarly well in both vehicles.
Conclusion
For users who regularly transport long or very bulky loads, the Mercedes-Benz GLE is the better choice due to the 12% longer cargo length with folded seats. For typical everyday use with normal shopping, luggage, or occasional cargo, the differences are minor and both models are practically comparable.
