Thing is. there is a HUGE difference between real 4 wheel drive, and All wheel drive.
4 wheel drive is when all 4 wheels have power to them. And so when you turn a true 4x4. The difference in wheel speed from the inside to the outside. Binds the axle, unless one tire can slip. Needing a slippery surface to slip on. OR the trany is burned to a crisp.
All wheel drive. Is usually only 2 wheels engaged at a time. One on the front, and one on the back. Should one, or both of those wheels slip. they are instantly disengaged, and the other two are engaged. Should those slip as well. The system tries to engage the other two again. And if that don't work. The system "CAN" disengage all four. No damage done. But the vehicle won't move.
So If you are never going off road / pavement. All wheel drive is usually good enough. But in heavy snow, mud, or sand. Real 4x4 is a must.
