BMW engineers are currently testing the upcoming M6 Gran Coupe at various locations. Recently this high performance four door saloon was spotted on the Nürburgring race track.
Just as the new M5 and M6 Coupe/Cabriolet, the M6 Gran Coupe will use the twin-turbo 4.4 litre V8 with 560 horsepower.
The M6 Gran Coupe features the same front and rear design as the M6 Coupe/Convertible and will have a carbon roof just like the M6 coupe.
The M6 Gran Coupe is expected to debut at the 2012 Paris auto show in September.
