Trunk comparison: Mercedes Benz GLC vs Tesla Model Y

Key Differences

The Tesla Model Y offers a significantly longer loading length: with the seats folded down, the trunk is 7.5 in (11%) longer than the Mercedes‑GLC, and with the first row of seats upright, the Model Y's advantage is even 7.1 in (19%). Conversely, the GLC is 5.9 in (16%) wider at its narrowest point than the Model Y.

Other, smaller differences: the height of the trunk opening is 2.8 in (10%) greater on the GLC, the width of the opening is 3.5 in (9%) greater on the GLC, the depth (loading edge to floor) is the same, and the loading edge height is only 0.4 in (1%) higher on the GLC.

Impact on Usability

The longer cargo area of the Model Y makes it more practical for long items like skis, lumber, or furniture parts; this advantage applies both with the seats folded down and in everyday use with the first row upright when passengers are still seated in the back. The larger narrowest interior space of the GLC, on the other hand, means better room for wide or bulky loads — wide boxes, suitcases, or bulky items fit more easily through the narrowest part of the trunk. The slightly higher trunk opening of the GLC makes it easier to lift tall items in, and the greater opening width (though less than 10% difference) supports inserting wide parts. Because depth and loading edge height are practically identical, both vehicles are similarly comfortable for lifting and vertical cargo space.
