The BMW M3 is a high-performance version of the BMW 3-Series small car BMW M3 BMW M models will be developed branch of the E30, E36, E46 and E90/E92/E93 3-series coupe and sold, sedan and convertible bodies derived. Common upgrades over the “standard” 3-series cars are much more powerful and responding (yet at times smaller) engines, improved handling / suspension, more aggressive aerodynamics / body, and multiple interior / exterior accents with the tri-color “M” ( Motor Sport) badge.

Based on the 1986 model year E30 3-series, the first M3 with a 2.3 L I4 engine S14B23 was introduced (or S14 in shorthand). The engine was on various design BMW genealogy, basic block layout of the M10 4 cylinder (found in 2002 and 320 series) bored on base and reinforced with similar specifications of the BMW M88 inline-6. The fixtures and the main architecture of the BMW M1 and M6 inline-6 cylinder was later adopted for aggressive breathing, which provides excellent performance for the day.

The most striking feature of the E30 M3 (compared to later iterations M3) is its racing pedigree. It was campaigned by BMW as well as other racing teams with Prodrive and AC Schnitzer competition in many forms of racing such as Rally, German, British, Italian, Belgian, French and Australian touring car.

One of the main reasons for the production of the car was the road for M3 Group A gay to stay touring car racing. One of the reasons often cited for establishing it was to compete with the “2.3-16V”-model Mercedes-Benz W201 190E, which was introduced in 1983, but that was only speculative. When the E30 M3 was top-level competition in her last year was the 2.5-liter S14 engine in full race trim a position more than 340 hp (250 kW) naturally aspirated engine.
