Trunk comparison: BMW X1 vs Mercedes Benz GLE

Key Differences
The Mercedes‑Benz GLE offers significantly more cargo length: with the seats folded down, the trunk is +11.8 in (≈18%) longer and with the first row of seats upright, +5.9 in (≈17%) longer than the BMW X1. Additionally, the trunk opening of the GLE is +3.5 in (≈13%) higher, which makes loading tall items easier.
In contrast, the BMW X1 has a considerably greater depth between the loading edge and trunk floor: +1.2 in (≈200%) compared to the GLE.
Impact on Usability
The longer cargo areas of the GLE specifically mean better options for long or bulky items (e.g., slats, skis, long boxes)—both with seats folded down and with normal seating. The higher trunk opening of the GLE also facilitates loading tall items, as less bending or tilting is required.
The greater depth of the BMW X1 (loading edge → trunk floor) creates more vertical space inside the cargo area and can allow bulky items to be recessed somewhat "deeper." At the same time, a deeper loading floor can make lifting and loading heavy objects somewhat less convenient, as they must be handled differently relative to the loading edge.
Small advantages for the GLE in width at the narrowest point (+1.6 in) and width of the opening (+1.2 in) are hardly noticeable in most everyday situations but can be decisive for especially wide loads.
The loading edge height above the road (GLE +2.4 in / ≈8%) slightly increases the required lifting height but is under 10% proportionally and only moderately affects everyday use.
