There have been rumors flying around about the new M5/M6 and one thing seems to be true, they are going with a V8 Twin Turbo instead of the V10 which is going to be interesting and it can be heavily modified. Now this design by Racer-X-Design has changed the look of this machine to a menacing beast, a little wider then the standard M6. They kept the basic design but gave it a different look.
