C55 AMG lighter than M#(according to that article at top)???.....thats wierd, I'm surprised.
I have a question, is the 5.4 liter Amg engine a good engine. I mean, if you compare horsepower to amount of liters, its not impressive at all, but the torque is decent. I think I red that it is tuned for low end power, is this true and does that explain the low hp/liter ratio?
