BMW carved a niche for itself by introducing the X6 coupe-SUV back in 2008, which was followed by the second-gen model in 2015. While the second-gen X6 is only three years old, BMW has decided to shift it to its CLAR (Cluster Architecture) platform, like it did with the latest X5. While various prototypes of the third-gen model were spotted in the US, the latest images of a heavily camouflaged test mule from Germany give us a better glimpse of the upcoming coupe-SUV.
