Whats the difference between AWD and 4WD? Luxury SUVS are AWD and have transfer cases with locking diffs. G Wagons, Range rovers, Cayennes. The luxury crossovers have limited slip diffs and brake torque vectoring.
Edit: Not sure why i am getting downvoted. Here are the specs to a G Wagon. AWD with front and rear diff locks.

- SkyPuncher 2y agoG wagon is a proper 4WD vehicle. It might be able to drive in AWD modes, but it has proper diffs to do it. There are loads of exceptions, but generally AWD vehicles have weaker or non-existent locking diffs. For example, I believe my AWD vehicle simulates locking diffs with clutch plates. Those clutches can and do slip. They’re effective at keeping the wheels “mostly locked” but not true 4WD. Further, most of the brake based torque vectoring required “slip detection” that’s only possible when a wheel spins. These systems aren’t really perfect in actually locking out motion on a free wheel. They kind of have to let them slip from time to time to check condition. These systems also tend to allow a lot of spin before they kick in - that years up roads.
