The BMW 3 Series is the compact luxury car line of the German automaker BMW since May 1975. Successor to the 2-door sporty sedans of the BMW "New Class", it has been produced in five different generations and in no less than five different body styles.
Because of the success of the
2002, the BMW E21 was developed to fill the 2-door sedan market and became the first BMW 3 Series. Released in 1975, it used 4-cylinder engines: the 1.6-L 316, the 1.8-L 318, the 2.0-L 320 and in late 1975, the fuel-injected 2.0-L 320i. In 1977, the 6-cylinder versions replaced the top models: the 2.0-L 320/6 for the 320, and the fuel-injected 2.3-L 323i for the 320i. In 1979, the 316 was upgraded with a 1.8-L engine while the 1.6-L was given to the new 315. The fuel-injected 318i replaced the 318. Also from 1977 to 1982, Baur converted E21 coupes into "targa"-style cabriolets, the TC1. All models were replaced in 1983 by the next generation of the 3 Series, the
BMW E30.
