Newer vehicles with limited slip differentials may offer some improvement, but more often you’ll find the slipping is not ‘limited’ enough to maintain forward progress. Automatic locking differentials also have their disadvantages. Aside from being noisy when disengaging, they can also upset the on-highway driving characteristics of your vehicle.
