BMW 1600 was one of the cars included in the so-called "new class". The new class consisted of a line of compact sedans produced by BMW and leading its report since 1962. Cars of the new class were equipped with engines from 1500 cmยณ to 2002 cmยณ. The BMW 1600 had an engine size of 1573 cmยณ (rounded 1600), as its name suggests.
