(December 2016) (Learn how and when to remove this template message) </Td> </Tr> <P> The main advantage of a limited - slip differential is demonstrated by considering the case of a standard (or "open") differential in off - roading or snow situations where one wheel begins to slip . In such a case with a standard differential, the slipping or non-contacting wheel will receive the majority of the power (in the form of low - torque, high rpm rotation), while the contacting wheel will remain stationary with respect to the ground . The torque transmitted by an open differential will always be equal at both wheels; if one tire is on a slippery surface, the supplied torque will easily overcome the available traction at a very low number . For example, the right tire might begin to spin as soon as 70 N ⋅ m (50 lb ⋅ ft) of torque is placed on it, since it is on an icy surface . Since the same amount of torque is always felt at both wheels, regardless of the speed which they are turning, this means that the wheel with traction cannot receive more than 70 Nm of torque either, which is far less than is required to move the vehicle . Meanwhile, the tire on the slippery surface will simply spin, absorbing all of the actual power output (which is a function of torque provided over time), even though both wheels are provided the same (very low) amount of torque . In this situation, a limited - slip differential prevents excessive power from being allocated to one wheel, and so keeps both wheels in powered rotation, ensuring that the traction will not be limited to the wheel which can handle the minimum amount of power . The advantages of LSD in high - power, rear wheel drive automobiles were demonstrated during the United States "Muscle - Car" era from the mid 1960s through the early 1970s . Cars of this era normally were rear wheel drive and did not feature independent suspension for the rear tires (but instead used a live axle). With a live axle, when high torque is applied through the differential, the traction on the right rear tire is lower as the axle naturally wants to turn with the torsion of the drive shaft (but is held stationary by being mounted to the vehicle frame). This coined the term "one wheel peel". As such, "Muscle - Cars" with LSD or "posi" (positraction) were at a distinct advantage to their wheel - spinning counterparts . </P> <P> Automotive limited - slip differentials all contain a few basic elements . First, all have a gear train that, like an open differential, allows the output shafts to spin at different speeds while holding the sum of their speeds proportional to that of the input shaft . </P>

Is limited slip differential the same as traction control
