It sounds like gear/differential whine in 1st/2nd/3rd gears - thought it seemed less noticeable in 3rd and couldn't hear it much at all in 4th/5th/6th. It got quieter when lifting off the trottle to the neutral point (modulating between acceleration/deceleration). This observation is admittedly wholistically unscientific however, didn't want to spend too much time tracing perceived faults in loaner cars .

I was pretty impressed with the 328 though. I sometimes wish I'd gone with a manual 328 as opposed to an auto 335.
