I am not very mechanically inclined, so I was hoping someone could answer this for me. If a WS6 and R/T both have a 5.7L engine, eventhough the R/T is a hemi, what makes the car comparable to the WS6? The WS6 must be much lighter and aerodynamic than the Charger, right? Does the hemi part really make up the difference? I mean I hear that the R/T is about 350 hp and the WS6 is about the same (actually, not what it was rated). Someone please explain.
