328I Introduction:
The 328i was introduced for the 1996 model year in North America, effectively replacing the 325i. It featured the larger M50B30 engine, offering increased performance. However, this manual specifically covers the 1993 model, which was a 325i in North America, but BMW may have used the 328 designation in other markets for models with similar engines or during specific production runs leading up to the major facelift. It's important to note the model nomenclature can be region-specific. For North America, the 1993 model would be a 325i (M50B25 engine). The manual title might be for a specific region or a broader E36 coverage that includes early models that might have been badged differently elsewhere. Assuming the manual is accurate for a 1993 E36 328i, it suggests a specific market or production run.
Manufacturing Locations:
Primarily Dingolfing, Germany; also Rosslyn, South Africa, and Spartanburg, USA (for later E36 variants).
