All that and more!  Really!
 Feels rocket fast because of the low end torque. 0 to 60 is only 0.6 sec. slower then the gas guzzling 4.8 liter gasoline version. I average 22.4 mpg. and I drive it like a sports car. The comfort stability and ride quality still astound me. For the first time I always want to drive... and everyone else asks to. The thing corners like a sports car and feels soooo smooth doing 100mph on the straight.  Sound system is superb. You can hear the engine if the sound system is not on but it's not intrusive. I don't have the sport package with the expensive wheels so the visual is an understatement but the highway ride quality is actually a lot better without the fat tires...go figure.
