Steyr Onbekend

The naming of the 92 series (also adapted for later models of the 91) refers to the vehicle's gross weight, followed by an "S" or "M" for civilian or military versions, followed by a number denoting tens of horsepower. Thus, a 210 PS 16 tonner would be called 16S21. Lighter models used Steyr's own transmissions, while heavier versions received ZF units. The axles were all Steyr's own, axles being a mainstay of Steyr's production.[5] The 92 series cab was also used by Britain's ERF beginning in the late 1980s, for their medium-weight ES series.[6] [Coincidentally, ERF became part of MAN in 2000.
