There are currently two types of Torsen differentials - the original "Type I" and the newer "Type II". The Type I Torsen uses crossed axis Helical Gears to increase internal friction when one wheel spins faster than the other. The Type II Torsen uses a parallel gear arrangement to achieve a similar effect. The Type I can be designed for higher torque bias ratios than the Type II, but typically has higher backlash and the potential for NVH issues. When a torsen differential is employed, the slower-moving wheel always receives more Torque than the faster-moving wheel. The Torsen does not have a preload so some traction is necessary in order to transfer torque. If one wheel were raised in the air, the Torsen would act like an Open Differential and no torque would be transferred to the other wheel. One of the most famous uses of the Torsen LSD is in many of the various Audi Quattro models, notably excluding the A3 and TT . It is also used, for example, in the Toyota Supra and Toyota Soarer (or Lexus SC430 ), the B5 platform revision of the Volkswagen Passat 4motion (based upon the Audi A4 ), and some versions of the Mazda MX-5/Miata The HMMWV uses two Torsens, front and rear, with a normal manually lockable center differential in the center.
