Generation:
Third generation 3 Series (E36), introduced in 1991 globally and late 1991/early 1992 in North America. The 328i replaced the 325i for the 1996 model year in North America, though this manual specifically covers the 1994 model year, which was the last year for the 325i in North America and the 328i's European debut year (or closely related models). This manual is highly valuable for understanding the M52 engine which debuted in 1994 in Europe.
Engine Transition:
The M52 engine (M52B28) introduced in the 328i in 1994 (globally) used a more modern aluminum block compared to the M50's iron block, offering weight savings and improved thermal management.
Manufacturing Locations:
Germany (various BMW plants), South Africa
