Noise Level under various condition (GL350 BT vs GL450)
Does any one have tested both GL350(Diesel) and GL450(GAS) in terms of noise level during idle, highway, low speed?
Thanks

Drive them both to compare for yourself - but you need to decide which model to drive 1st..
The way that works is this..- if you drive the GL350 1st - and then the GL450 - the GL450 will sound a "little quieter"...end result GL350 will be very impressive..
..if your drive the GL450 1st - then drive the GL350 next - you will hear the "slight" increase in running noise at idle and low/street speed..and you will be impressed by the GL450..
Psychoacoustics thing...

I drove both and the only difference I noticed was the way the 450 drove compared to the 350. I LOVE the way the 450 drives but I hate the way it sucks up gas so i opted for the lesser powered diesel option of the 350. Most people can't even tell it's a diesel and it's very quite from the interior honestly.
