If you dissect what GLE stands for in the Mercedes-Benz lineup, the meaning is quite clear. The "GL" at the beginning of its name indicates that this model is an SUV. You will notice a similarity in the names of other Mercedes-Benz SUVs in this regard. The "E" at the end of its name dictates that this is the midsize model in their SUV lineup, similar to their midsize E-Class sedans.
