It's really not much of a contest, is it ? There is no doubt that the last ten years (if not more), have witnessed tremendous engine technology improvements. Yet, I am still happy with 6.9 liters of 'slow coach' acceleration. The torque figure is still more than adequate. Noise wise - AMG have tuned a toxic exhaust noise into their system - it is quite exhilarating and certainly puts a smile on your face. Regards Styria
