The M6 Gran Coupe was expected to debut early next year at either Detroit or Geneva. But today we get a sneak peak via the interwebs and someone with a sneaky cellphone camera.
The M6 Gran Coupe should debut at dealers this late spring or summer. The S63Tü twin turbo V8 will be powering the car with the well known 7 speed M-DCT motivating it all. Other than the wheels we don ‘t expect many differences between the M6GC and the the standard M6. Except for you know, the four doors.
