This is an extract from a BMW road test report appeared on link below:

...BMW has judged the refinement of the 745i to perfection. At idle this is an exceptionally quiet car, and it remains so at any speed up to 125mph, when the only sound filtering into the cabin is a gentle wind flutter. You simply don't hear the engine unless you rev it out, the assured mechanical hum at the 6600rpm change-up point reminding you that this is a BMW, not a Lexus. ...
I think this is outrageous and another pathetic attempt by BMW to hit at Lexus.
