BMW M2/M3/M4

The BMW M3 is a high-performance version of the BMW 3 Series, developed by BMW's in-house motorsport division, BMW M GmbH. M3 models have been produced for every generation of 3 Series since the E30 M3 was introduced in 1986. The initial model was available in a coupé body style, with a convertible body style made available soon after.

Engine

The E30 M3 used the BMW S14 four-cylinder engine, a high-revving DOHC design with a head closely based on that of the BMW S38 six-cylinder engine and the block from the BMW M10 four-cylinder engine with a 7,250 rpm redline.

Special Editions

In 1987 an "Evolution" model (also called "EVO1") was released. Although not designated by BMW as an Evolution model, these had a revised cylinder head (designated by an "E" stamp) to improve performance. Power was unchanged from the standard M3.

Motorsport

The M3 E30 competed in many forms of motorsport and was highly successful in touring car racing. In full race trim, the 1988 M3's 2.3 L (140 cu in) naturally aspirated engine was rated at approximately 221 kW (300 PS; 296 hp).

Special editions

In 1994, BMW produced the limited-edition M3 GT as a racing homologation special for Europe, in order to compete in the FIA-GT class II, IMSA GT and international long-distance races. A total of 356 cars were produced, all in left-hand drive for mainland Europe.

Production

Production of the E36 M3 began in September 1992 and was discontinued in August 1999. The majority of cars were produced at the BMW Regensburg factory in Germany; however, a small number of low compression right-hand drive cars were assembled at BMW's plant in Rosslyn, South Africa. In total, 46,525 coupés, 12,114 convertibles, and 12,603 saloons were produced.
