 I traded my Ranger Edge in Nov 06 and have never seen such power from a smaller truck. You feel the power on interstate and it does not hesitate off road. All stock, I have pulled out a Silverado and a Jeep and then drove through what they got stuck in.  The push button locker makes a world of difference. For a 4WD it could be a little higher though. Overall, the power is there when you need it and off roading is fun as hell.
