The AMG 5.5 engine is no where near as entertaining as the other two IMO. I'm not a fan of turbo set ups in general. Although it is a VERY fast engine and is easily tuned, I prefer the feel, responsiveness, revving ability and sound of both the S65 and AMG 6.2.
..any opportunity I have to jump in the 6.2 I will take and then be able to discuss more intelligently. I just responded to the thread as I feel that what BMW has accomplished with the S65 is simply amazing. Come Spring time I may very well be back in one.
