When driving moderatly, this happens at about 55mph/1500rpm. The engine will lug at that rpm and that makes the car vibrate. Above 60mph, you done notice it and I guess its not really a problem. It used to bother me until I figured out what was going on and now I don't even think about it anymore. Great car, otherwise.
I avoided 50-55 mph unless I downshifted into 4th; I never noted much, if any, drop in mpg if I kept a light throttle.
