Trunk comparison: Ford S-MAX vs Mercedes Benz GLE

Key Differences
The Ford S‑Max offers significantly more cargo space comfort in several key areas: the height of the trunk opening is 4.7 in (15%) higher on the S‑Max, and the depth of the trunk (loading edge to trunk floor) is 1.2 in (200%) greater on the S‑Max.
Additionally, the loading edge on the Mercedes‑GLE is 7.9 in (35%) higher above the ground than on the S‑Max.
Smaller differences: the S‑Max has a 1.6 in (2%) longer loading length with the seats folded down and 2.8 in (7%) more length with the first row of seats upright; the GLE is 0.8 in (2%) wider at its narrowest point and the opening width is 1.6 in (4%) larger.
Impact on Usability
Due to the higher trunk opening and greater depth, the S‑Max offers noticeable advantages when loading tall or bulky items: larger boxes, furniture parts, or tall plants can be more easily accommodated in an upright position without hitting the opening.
The lower loading edge on the S‑Max combined with the deeper cargo floor also reduces lifting effort — loading heavy items is physically less demanding than with the GLE.
On the Mercedes‑GLE, the significantly higher loading edge makes handling heavy or awkward loads more difficult; loading requires more physical effort or aids (e.g., a ramp).
The slightly greater width at the narrowest point and the larger opening width of the GLE (each by a few centimeters) barely improve loading wider items in everyday use but do not compensate for the disadvantages in height and lifting effort.
Conclusion: Those who frequently load tall or heavy items and value easy loading and unloading benefit from the higher opening, greater depth, and lower loading edge of the S‑Max. The GLE offers marginally more width but is less practical when handling heavy or tall cargo.
