This is the first photo with the upcoming 2013 BMW M6 GranCoupe without wearing any sort of camouflage. To be launched in 2013.

We saw several batches of spy photos with the upcoming 2013 BMW M6 GranCoupe but this is the first picture where we see the four-door coupe without any sort of camouflage. Wearing blue M brakes, futuristic wheels and more aggressive side skirts, this photo was taken in what appears to be a work shop. There’s another one in the background that has yellow ceramic brakes.

It can be considered as a four-door version of the standard M6 coupe and most likely it will be powered by the same V8 4.4-liter twin-turbo engine found under the hood of the new M5, but chances are that BMW’s engineers will squeeze more ponies from that engine, somewhere around the figure of 591 hp (441 kW).

Expect an official reveal next year when the car is scheduled to go on sale.

Thanks to Kevin for the tip!
