The BMW M3 is a high-performance version of the BMW 3 Series, developed by BMW's tuning branch BMW M. M3 models have been derived from the E30, E36, E46 and E90/E92/E93 3-series, and sold with coup?©, sedan and convertible body styles. Upgrades over the "standard" 3-Series automobiles include more powerful and responsive (yet at times smaller) engines, improved handling/suspension/braking systems, aerodynamic body enhancements, and interior/exterior accents with the tri-color "M" (Motorsport) emblem.

Based on the 1986 model year E30 3-Series, the first M3 was introduced with a 2.3 L I4 S14B23 engine (also known as S14). The engine design was based on various BMW parts: basic block layout from the M10 4 cylinder (found in the 2002 and 320 series) overbored and reinforced to similar specifications of the BMW M88 inline-6. The valve train and head architecture from BMW's M1 and, later, M6 inline-6 cylinder was adopted for aggressive breathing.

In contrast to later M3 iterations, the E30 M3 was campaigned by BMW as well as other racing teams including Prodrive and AC Schnitzer competing in many forms of racing including rally as well as German, British, Italian, Belgian, French, and Australian touring. The production of the E30 road car was to homologate the M3 for Group A Touring Car racing. It was to compete with the "2.3-16V"-model of the Mercedes-Benz W201 190E that was introduced in 1983. In its final years of competition, the 2.5 liter S14 engine in full race trim was capable of over 250 hp (190 kW) naturally aspirated.

The third car road-going version produced 195 bhp (145 kW; 198 PS) (catalyzed model). Evolution models (not sold in North America) continued with 2.3 liters but adopted revised exhaust-cam timing, increased compression along with the lack of a catalyst producing approximately 215 hp (160 kW). Later the Sport Evolution model production run of 600 (sometimes referred as Evolution III) increased engine displacement to 2.5 L and produced 238 hp (177 kW; 241 PS). An additional 786 convertibles were also produced.

The E30 M3 differed from the rest of the E30 line-up in many ways. The M3 was equipped with a revised stiffer and more aerodynamic body shell as well as "box flared" wheel-arches to accommodate a wider track with wider and taller wheels and tires. The only exterior body panels the standard model 3-series and the M3 shared were the hood, roof panel, and sunroof.

The E30 M3 differs from the standard E30 by having a 5x120 wheel bolt patern. The E30 M3 had increased caster angle through major front suspension changes. The M3 had specific solid rubber offset control arm bushings. It used aluminum control arms and the front strut tubes where changed to a design similar (bolt on kingpins and swaybar mounted to strut tube) to the E28 5-series. This included carrying over the 5 series front wheel bearings and brake caliper bolt spacing. The rear suspension is a carry over from the E30.
