E320 CDI--whats the engine sound like?
hey! I'm just curious lol...any one who has the new CDI..what does the engine sound like?Like a Mercedes gasoline V6 or totally different??thanks!!
When at crusing speeds you simply cannot tell other than when you hit the throttle you end up in the back seat!!

The engine does "growl" like a diesel under heavy acceleration. When crusing at highway speeds, the engine's sound fades into the background. It is not a significant source of noise compared to other "normal" background highway noises.
So, in answer to your original question, yes, the diesel engine does sound different compared to the gas E's, but that is not to say it's either worse or better, just different.
I think most people would not find the diesel's sound objectionable.
Once underway, I couldn't detect any auditory evidence that I was driving a diesel. I felt the engine was smoother than the gas 3.2, not surprising as the CDI is an inline 6 which is inherently balanced, while the gas 3.2 is a V6.
