A limited-slip differential (LSD) is a type of differential gear train that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction, a brand name owned by General Motors and originally used for its Chevrolet branded vehicles.

The Volkswagen Type 82 Kübelwagen, or simply Kübel, contractions of the original German word Kübelsitzwagen, is a military light utility vehicle designed by Ferdinand Porsche and built by Volkswagen during World War II for use by the Nazi German military. Based heavily on the Volkswagen Beetle, it was prototyped and first deployed in Poland as the Type 62, but following improvements entered full-scale production as the Type 82. Several derivative models, such as the Kommandeurswagen, were also built in hundreds, or in dozens.
