Rides : BMW M6 Gran Coupe To Get 580hp?

According to some internals from BMW the M6 Gran Coupe is on the company’s roadmap.

The third iteration of the 6-Series after the two-door Coupe and Convertible models will most likely be called the 6-Series GT or the 6-Series Gran Coupé and will reach showrooms in the first half of 2012.
At the exterior, the new 6 Series Gran Coupe is quite a bit longer than the 6-series coupe and convertible.
Now, according to 6post.com, the new BMW 6er Gran Coupe will receive the all new and much discussed Tri-Turbo diesel which will be found in the BMW X6xDrive50d with 354PS. Originally intended but dialed back for the M5 due to the conception of the Gran Coupe , Gran Coupe will be the flagship M model.
To achieve its full potential, the engine will be mated to a similar transmission found in the new M5, a 7-speed DCT.
