The newcomer raises the number of Mercedes SUV models to eight, indicating the significance to the brand of a sector that accounts for a third of its global sales. The GLE Coupé joins an ever-growing segment of style-focused variants of traditional high-riding models and can also count the Porsche Cayenne Coupé, Audi Q8 and Range Rover Velar as competitors.
