all i know is that it is a V6 and it's NOT trail rated, but I don't care about that. It is 4 x 4 so it's electronically controlled if the wheels slip the others catch, there is no locking of hubs, and no switch i have to turn, or button to push. Not sure if that helps but so far so good and I'm getting about 17 mpg which is only 3 less then the altima.
