The BMW E30 is the second generation of BMW 3 Series, which was produced from 1982 to 1994 and replaced the E21 3 Series. The model range included 2-door coupe and convertible body styles, as well as being the first 3 Series to be produced in 4-door sedan and wagon/estate body styles. It was powered by four-cylinder petrol, six-cylinder petrol and six-cylinder diesel engines, the latter a first for the 3 Series. The E30 325iX model was the first BMW to have all-wheel drive.
The BMW M3 utilised a widened and heavily redesigned variation of the two-door body style, therefore the M3 shares few body parts with other E30 models. The M3 suspension is also significantly different from regular E30 models, including five-lug wheel bolts.
The first BMW M3 was based on the E30 3 Series and was intended to be a homologation special to satisfy the Deutsche Tourenwagen Meisterschaft and Group A Touring rules, which required a total of 5,000 cars to be built. It was presented to the public at the 1985 Frankfurt Motor Show, and began production from March 1986 to June 1991. The E30 M3 was mainly produced in the coupé body style, but limited volumes of convertibles were also produced.
