The Automatic Locking Differential improves handling during acceleration in curves or when one of the driving wheels is on a surface with a different grip coefficient than the others. In short, it ensures the best rotational speed for each of the driving wheels, thus preventing loss of the car’s dynamics during evasive maneuvers or potentially dangerous situations like driving with a lateral set of wheels on a slippery surface.
This is done by “locking” both wheels on a driving axle together as if they were on a common shaft. This forces both wheels to turn in unison, regardless of the traction (or lack of it) available to either wheel individually, making it a very efficient solution for off-roading if found on an all-wheel driven vehicle.
