List of Mercedes-Benz trucks
Mercedes-Benz internal model designations (in-house design codes) were always more or less just consecutively allocated design codes devoid of any deeper meaning. For the passenger cars they are so-called W-numbers, from German word Wagen (=car). For example, W202 is C-class, W220 is S-class etc. This system started in 1926 and the numbers are consecutive continued till now. From the 1970s letter W is used for saloons, while the other letters have been add for the different body types (f.e. W212 is E-class saloon, V212 is E-class limousine, S212 is E-class estate etc.). For the commercial vehicles for early decades letter L was used instead of letter W (German word Lastwagen means a truck). From the 1950s letter L was omitted, resulting in just 3 numbers code. Sometimes word Baumuster (model) or Baureihe (model line) was used, like Baumuster 352 (or in short BM352) or Baureihe 352 (in short BR.352). So, basically, with or without a letter(s) in front, there is unique 3-number code, which determine every Mercedes-Benz car. As for the trucks, 300-i.e. numbers were used till the 1980s to code Mercedes commercial vehicles, 600-i.e. numbers were used in the 1980s and 1990s, and 900-i.e. numbers have been used from the introduction of Sprinter (1995) and Actros (1996).
