The car does not drone. It has a unique sound specific unto itself. Lots of the haters have complained that it is too quiet and doesn't sound like a Ferrari V-12, which it's not.
If you are on the highway, and you don't want to hear the exhaust as much you simply switch down to "Sport" mode and the car essentially drives like a Honda Accord, but the power is lurking if you need to make a quick "spurt" through traffic. If you find yourself in a twisty canyon, you simply switch back to "Sport+" and you're off to the races in a supercar.....
I do NOT consider the car to be plush. It is a FIRM ride, but I expect that in a car designed to perform on the track, so it doesn't bother me at all. I feel every crack in the road, but on a smooth surface it is smooth as silk, and very confidence inspiring cornering whether on the street or on the track.
