A short brief in history: BMW has launched the idea of a SUV-coupe with the first generation BMW X6 in 2008. With the occassion of the third generation Mercedes ML facelift (W166) in the second half of 2015, Mercedes-Benz has changed the name ML in GLE and launched a SUV-coupe version (C292).

The new BMW X6 is as big as the former generation with a 26 mm increase in length to 4,935 mm and with a 15 mm increase in width to 2,004 mm.

The headroom is bigger at the first contact but the car looks more ugly from the profile.
