Is it safe to assume that the R500 will get the S-class's DOHC 388hp 5.4 liter V8 for 07'? I'd say so being that the Audi Q7 is getting the 350hp FSI V8....

Good listing of engines. I would not be surprised that the new V8 might come mid-year next year...or as soon as they run out of the old blocks.
